      <description>&lt;p&gt;When it comes down to choosing a cloud storage provider, it’s essential to consider an AWS EC2 backup solution that’s simple and easy for both servers and at the application level. It’s vital to understand how to back up the Amazon Web Services (AWS) EC2 server correctly because of the risks involved in improper restore in case of a disaster.&lt;/p&gt;

&lt;p&gt;&lt;a&gt;Table of Content&lt;/a&gt;&lt;/p&gt;

&lt;ol&gt;
    &lt;li&gt;
&lt;ol&gt;
    &lt;li&gt;
Backup Solution for Raw AWS EC2 Server
&lt;ol&gt;
    &lt;li&gt;First Method - EBS Snapshot&lt;/li&gt;
    &lt;li&gt;Second Method: Amazon Machine Image&lt;/li&gt;
    &lt;li&gt;Third Method: EC2 Backup to S3&lt;/li&gt;
    &lt;li&gt;Fourth Method: Simple Backup&lt;/li&gt;
&lt;/ol&gt;


&lt;/li&gt;
    &lt;li&gt;
Cloudways Makes AWS EC2 Backups Easy

&lt;ol&gt;
&lt;/ol&gt;


&lt;/li&gt;
&lt;/ol&gt;
&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Consider the example of an agency. Agencies often have multiple clients, and they usually handle a massive volume of data on behalf of these customers. To speed up data backup, the agencies often backup entre servers. This way, they’re able to consolidate all the data in a handy archive that can be used in case of a disaster or server migration.&lt;/p&gt;

&lt;p&gt;On the other hand, agency customers often have a much smaller number of active applications. They prefer application-level backups because they are not concerned with server-level operations.&lt;/p&gt;

&lt;p&gt;Since AWS EC2  is a leading IaaS provider, I would describe how to an AWS EC2 backup is performed on an unmanaged server and go into the simplicity of backing up a Cloudways &lt;a href="https://www.cloudways.com/en/amazon-cloud-hosting.php" rel="noopener"&gt;managed EC2 server&lt;/a&gt;.&lt;/p&gt;

&lt;h2 id="backup"&gt;Backup Solution for Raw AWS EC2 Server&lt;/h2&gt;

&lt;p&gt;Unmanaged EC2 backup on the server can get complicated, even for experienced users. To make things easier, Amazon offers various AWS EC2 backup solutions. Here, I’ve highlighted four of these AWS backup strategies.&lt;/p&gt;

&lt;h3 id="ebs-snap"&gt;Elastic Block Storage&lt;/h3&gt;

&lt;p&gt;Elastic Block Storage (EBS) is designed for an EC2 instance for intensive workloads at any scale. EBS is a high-performance block storage service which can handle a broad range of workloads such as:&lt;/p&gt;

&lt;ol&gt;
    &lt;li&gt;Enterprise Applications&lt;/li&gt;
    &lt;li&gt;Relational &amp;amp; Non-relational databases&lt;/li&gt;
    &lt;li&gt;Big Data Analytics Engines&lt;/li&gt;
    &lt;li&gt;Media Workflows&lt;/li&gt;
&lt;/ol&gt;

&lt;h3&gt;First Method - EBS Snapshot&lt;/h3&gt;

&lt;p&gt;One way of using EBS for backup is to create a snapshot of EBS volume used by EC2. EBS snapshot works as an external storage device. The user saves the instance at a given time and can restore it later (if the need arises).&lt;/p&gt;

&lt;p&gt;The process is quite straightforward but and requires the machine to stop processing user requests. This can be an issue for users communicating with the hosted application(s). The working EBS volume is unmounted for the backup process as it’s not possible to backup a volume that is still in use.&lt;/p&gt;

&lt;p&gt;To start the process, log in to the EC2 console and select the EC2 snapshot tool. Follow the on-screen instructions. Note that the snapshot creation can take several hours, depending on the volume of the data on the EBS.&lt;/p&gt;

&lt;p&gt;Once the snapshot has been created, it can be used to restore data in case of disaster recovery or for other data retrieval purposes.&lt;/p&gt;

&lt;p&gt;Thought EBS volume snapshot appears to be a smooth process; there are three significant issues:&lt;/p&gt;

&lt;ol&gt;
    &lt;li&gt;
&lt;ol&gt;
    &lt;li&gt;The process is manual and could take a lot of time.&lt;/li&gt;
    &lt;li&gt;The machine needs to be stopped, and the volumes need to be unmounted. This can affect user interaction with the applications deployed on the server.&lt;/li&gt;
&lt;/ol&gt;




&lt;/li&gt;

&lt;/ol&gt;

&lt;h3 id="ami"&gt;Second Method: Amazon Machine Image&lt;/h3&gt;

&lt;p&gt;Amazon Machine Image (AMI) provides the required information for launching an EC2 instance. An AMI is a master image that comprises templates, a preconfigured operating system, configuration files, and other supporting software. In effect, the AMI determines the working environment for the user and the applications.&lt;/p&gt;

&lt;p&gt;A typical AMI comes with:&lt;/p&gt;

&lt;ol&gt;
    &lt;li&gt;
&lt;ol&gt;
    &lt;li&gt;All the necessary permission to use the AMI for launching instances from authorized AWS accounts&lt;/li&gt;
    &lt;li&gt; An operating system, application server environment &amp;amp; the main application (Template for the root volume instance)&lt;/li&gt;
    &lt;li&gt;A block device mapping which ensures specified volume is attached to the launched instance&lt;/li&gt;
&lt;/ol&gt;




&lt;/li&gt;

&lt;/ol&gt;
&lt;br&gt;&lt;br&gt;
AMI can be used for EC2 backup. Once a custom-built AMI is deployed on EC2 instance, it can be used to create a clone of the server. In case of disaster, this clone can be used to restore the application environment and data.

&lt;p&gt;As stated above, when backing up an AWS EC2 instance or an EBS instance, the machine instance needs to be stopped. However, there are a few exceptions in this case. If a user has opted for the XFS file system, it freezes while taking backups without the requirement of stopping the entire instance.&lt;/p&gt;

&lt;p&gt;However, according to expert opinion, stopping the instance is preferred before taking the backup as it minimizes the chances of data corruption.&lt;/p&gt;

&lt;p&gt;To start the process, log in to the AWS console and stop the instance you wish to back up.&lt;/p&gt;

&lt;p&gt;Navigated to Actions &amp;gt; Image. Click Create Image and follow the onscreen instructions for creating the new AMI.&lt;/p&gt;

&lt;p&gt;Although it looks simple, it’s slightly more complicated when compared to taking snapshots because of the more detailed process. There is no doubt AMI backups provide the convenience of configuration data along with operating system packages into a single image. Still, this backup method relies heavily on manual work and could get very time intensive.&lt;/p&gt;

&lt;h3 id="s3"&gt;Third Method: EC2 Backup to S3&lt;/h3&gt;

&lt;p&gt;Simple Storage Service (S3) is a storage facility designed for web-based enterprise-level applications. In many cases, S3 is the ideal solution for online backup/archiving of application data. AWS S3 provides a simple interface for storing and retrieving any volume of data, from anywhere on the web, at any time.&lt;/p&gt;

&lt;p&gt;Unlike the previous methods (that are manual), EC2 Backup to S3 processes can be automated with the help of a command-line interface (CLI). The automation is based on several bash scripts.&lt;/p&gt;

&lt;p&gt;Here is an example of bash scripting for the backup process:&lt;/p&gt;

&lt;h1&gt;
  
  
  !/bin/bash
&lt;/h1&gt;

&lt;pre class="EnlighterJSRAW"&gt;aws ec2 create-snapshot --volume-id vol-xxxxx --description "Backup: `date`."&lt;/pre&gt;

&lt;p&gt;The script creates a snapshot volume command on AWS CLI, setting up a snapshot of the EBS volume.&lt;/p&gt;

&lt;p&gt;To use the AMI Image approach, swap ‘create image’ for ‘create snapshot’ and the script will look like this&lt;/p&gt;

&lt;h1&gt;
  
  
  !/bin/bash
&lt;/h1&gt;

&lt;pre class="EnlighterJSRAW"&gt;aws ec2 create-image --instance-id i-1234567890abcdef0 --name "Image Backup" --description "Backup AMI"&lt;/pre&gt;

&lt;p&gt;The only complication in the process is the need to remember these bash scripts. To back up multiple EC2 instances, &lt;a href="https://www.cloudways.com/blog/schedule-cron-jobs-in-php/" rel="noopener"&gt;set up a cron job on the server&lt;/a&gt; with script deployed properly.&lt;/p&gt;

&lt;h3 id="simple"&gt;Fourth Method: Simple Backup&lt;/h3&gt;

&lt;p&gt;At some point, a user desires just to back up specific data rather than the entire instance. This is a right approach as it can minimize storage costs. Similarly, instead of placing data on an online storage service, an offline backup can be recommended. However, offline backup has significant risks such as a system crash, virus or malware intrusion and/or data leaks, etc.&lt;/p&gt;

&lt;p&gt;This approach works best when the system does not have a vast amount of custom configuration settings. Although, recovery during an emergency situation may get complicated since a new instance needs to be built instead of recreating one from an existing AMI or EBS Snapshot.&lt;/p&gt;

&lt;p&gt;Furthermore, this method also negatively affects the business bottom line as AWS backup pricing is an additional cost to the business. Every AWS EC2 backup request has a price attached to it; hence, that’s an important consideration when choosing cloud storage providers.&lt;/p&gt;

&lt;h2 id="cloudways"&gt;Cloudways Makes AWS EC2 Backups Easy&lt;/h2&gt;

&lt;p&gt;Rounding up the four methods of backing up the AWS EC2 backup, it’s important to note that these methods are time-consuming and need a good knowledge of AWS server operation. In a scenario where someone new to the platform needs to create a backup, the process is not intuitive and can appear to be a huge hassle.&lt;/p&gt;

&lt;p&gt;On the other hand, Cloudways makes the process of creating EC2 backups simple and straightforward. There’s no requirement to code. It’s as simple as &lt;a href="https://support.cloudways.com/how-to-backup-my-server/" rel="noopener"&gt;following a few steps&lt;/a&gt; and et voila!&lt;/p&gt;

&lt;h3 id="app"&gt;Application Backup&lt;/h3&gt;

&lt;p&gt;To simplify the backup process, Cloudways also allows users to back up individual applications. The process is straightforward.

      <title>IaaS vs PaaS: Infrastructure as a Service VS Platform as a Service</title>
      <dc:creator>Salman Saleem</dc:creator>
      <pubDate>Thu, 07 Nov 2019 08:12:34 +0000</pubDate>
      <link>https://dev.to/salmansaleem920/iaas-vs-paas-infrastructure-as-a-service-vs-platform-as-a-service-5e0g</link>
      <guid>https://dev.to/salmansaleem920/iaas-vs-paas-infrastructure-as-a-service-vs-platform-as-a-service-5e0g</guid>
      <description>&lt;p&gt;To begin with, many businesses are going online. They are relying heavily on the cloud to facilitate their clients, which demands to collect, storing, and processing a vast amount of data before it can be presented to the end-user as information. This is where cloud-based web applications come in to play. In this article, we’re going to discuss IaaS vs. PaaS in detail so that you can grasp a better understanding of how cloud-based services can help you scale your business.&lt;/p&gt;

&lt;p&gt;They help you store, process, and retrieve data and then present it as information – forms, interactive content management systems, shopping carts, word and spreadsheet processing apps, and so on – before your clients so that you can scale your business with minimum effort.&lt;/p&gt;

&lt;h2&gt; Introducing Web Applications&lt;/h2&gt;

&lt;p&gt;Web applications let you integrate your data and consolidate everything into a single place, which minimizes the chances of human error and makes data management more efficient. You can launch them in a browser window and access them from any device or operating system. This greater accessibility, coupled with convenient scalability and maintenance, means that web applications are the way to go.&lt;/p&gt;

&lt;p&gt;Web applications require a server to run, and the majority of them rely on the cloud. Cloud-based applications can be thought of as web applications that can also be accessed when you’re offline.&lt;/p&gt;

&lt;p&gt;Now that you’ve established a better understanding of web applications, let’s move on to understanding IaaS vs. PaaS carefully. But first, what is IaaS and PaaS?&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;IaaS = Infrastructure as a Service&lt;/li&gt;
&lt;li&gt;PaaS = Platform as a Service&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;Differences Between IaaS vs. PaaS &lt;/h2&gt;

&lt;p&gt;There are some stark differences between IaaS and PaaS. Unlike PaaS, IaaS offers its customers direct access to its cloud servers and storage. It offers more flexibility, scalability, and networking layers. You don’t have to buy and install underlying infrastructure because you can outsource it instead. You can demand and acquire resources and pay for them as you go.&lt;/p&gt;

&lt;p&gt;When you compare cloud infrastructure as a service vs. platform as a service, IaaS can be more resilient than PaaS. The resilience is purely dependent on the vendor you choose. The same goes for security, as well. Typically charged per hour upon the usage of the services, IaaS costs can climb up because of the precise nature of billing.&lt;/p&gt;

&lt;p&gt;On the other hand, PaaS lets you tackle advanced high-level programming by streamlining and simplifying the process. This makes the development of apps more cost and time effective. The price, however, climbs up with the upscaling of your application. Once you commit to a PaaS provider, you’re locked in the environment and interface you have selected. That’s one of the differences between IaaS vs. PaaS.&lt;/p&gt;

&lt;p&gt;With the core differences between IaaS and PaaS mentioned, we can now proceed to grab an in-depth understanding of both.&lt;/p&gt;

&lt;h2&gt;What is IaaS?&lt;/h2&gt; 

&lt;p&gt;Picking the right Infrastructure as a Service from a number of cloud providers can be a bit tricky. Hence, we’re here to help you select a cloud infrastructure that can prove to be the right fit for your business.&lt;/p&gt;

&lt;p&gt;But first, when it comes to IaaS vs. PaaS, you must know the three significant milestones in its evolution.&lt;/p&gt;

&lt;h3&gt;Starting From The Beginning with Dedicated Servers&lt;/h3&gt;

&lt;p&gt;The root of all cloud hosting infrastructure stems from data centers filled with servers, switches, routers, storage options, and gears for other networks. IaaS or PaaS both come from the same hood, i.e. many servers in a huge room.&lt;/p&gt;

&lt;p&gt;By adding layers of abstraction, they assist in making management more manageable and help businesses by automating manual or slow tasks so that they can scale seamlessly.&lt;/p&gt;

&lt;p&gt;Here’s an overview of the pros and cons of dedicated servers.&lt;/p&gt;

&lt;h4&gt;The Pros&lt;/h4&gt;

&lt;p&gt;&lt;b&gt;Performance&lt;/b&gt; &lt;br&gt;
You can use the computer without any extra overheads of abstraction layers.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Reliability &lt;/b&gt;&lt;br&gt;
With no layers of abstraction or virtualization, there are fewer things that can go wrong.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Resource Utilization&lt;/b&gt;&lt;br&gt;
Dedicated servers don’t allow processes to fight with other virtual machines or methods for resources such as CPU, memory, or bandwidth.&lt;/p&gt;

&lt;h4&gt;The Cons&lt;/h4&gt;

&lt;p&gt;&lt;b&gt;Unable to Clone&lt;/b&gt;&lt;br&gt;
You can’t clone a dedicated server easily. There is no concept of AMI for a dedicated server.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Cost&lt;/b&gt;&lt;br&gt;
In most cases, you’ll pay for the hardware upfront as well as pay to house it in a colocation facility, or you’re leasing them from a hosting provider. Either way, you cannot quickly terminate the server when you’re not using it to save costs, so you need to be careful about your financial planning.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Management Hassle &lt;/b&gt;&lt;br&gt;
Every process or application that is running on a dedicated server is running on the same operating system. To run everything on the same server makes it difficult to optimize the OS for use in each case. For instance, for scalability, generally dedicated servers handle a single task, like either being a web server or a database server.&lt;/p&gt;

&lt;h3&gt;Virtualization – Making Things Easier &lt;/h3&gt;

&lt;p&gt;Despite the pros of dedicated server hosting, the cons greatly outweigh them, amongst which its cost is a significant factor. With the increasing speed of deployments and companies fighting to outperform their competitors, virtualization became a natural next step in the evolution of data centers.&lt;/p&gt;

&lt;h3&gt;What is virtualization?&lt;/h3&gt;

&lt;p&gt;In simple terms, virtualization is a process that lets you split up your dedicated server into smaller virtual servers that only have access to a part of the total resources of the physical server.&lt;/p&gt;

&lt;p&gt;You can take a physical server with two quad-core CPUs and 16GB RAM, and turn it into eight virtual machines with 1CPU and 2GB RAM each.&lt;/p&gt;

&lt;p&gt;Some examples of virtualization technologies you may have heard before, including Xen, KVM, VMware, and Hyper-V, etc.&lt;/p&gt;

&lt;h4&gt;The Pros&lt;/h4&gt;

&lt;ul&gt;
&lt;li&gt;You can clone virtual machines as per your needs.&lt;/li&gt;
&lt;li&gt;You can backup virtual machine images for safekeeping or disaster recovery.&lt;/li&gt;
&lt;/ul&gt;

&lt;h4&gt;The Cons&lt;/h4&gt;

&lt;ul&gt;
&lt;li&gt;Using virtualization means added overheads and potentially degraded performance.&lt;/li&gt;
&lt;li&gt;VMIs aren’t portable across hosting providers.&lt;/li&gt;
&lt;li&gt;Dealing with virtual machines is still a manual effort, and requires a lot of management time and expertise.&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;Evolution — Virtualization becomes IaaS&lt;/h3&gt;

&lt;p&gt;Whenever people talk about “cloud,” they are technically referring to IaaS – Infrastructure as a Service. So what is IaaS? In simple terms, it is the virtualization of someone else’s hardware, managed via Application Platform Interface (API). It offers code-based access to cloud computing, storage, network configuration, and resources.&lt;/p&gt;

&lt;p&gt;It treats data center resources as a utility. When needed, it lets you request a new virtual machine. You can terminate it whenever you’re done with it and pay only for what services you consume. Amazon pioneered it with the launch of Amazon Web Services (AWS) in 2006. It gave developers superpowers:&lt;/p&gt;

&lt;p&gt;They were able to conceive an idea and launch it immediately. If it’s a success, they were able to grow their server footprint quickly, and in case of a failure, they were able to shut it down and incur nominal costs.&lt;/p&gt;

&lt;p&gt;Datacenter automation became more powerful. Fully automated infrastructure became an achievable reality and gave rise to the concept of Infrastructure as Code. Although autoscaling was not possible in the past, now IaaS can help businesses autoscale as per their demand.&lt;/p&gt;

&lt;p&gt;Automating different areas of a data center followed shortly, with storage, networking, and other systems that need specialized skillset in order to get the API treatment, and opening up stronger possibilities to the developer community across the globe.&lt;/p&gt;

&lt;h3&gt;Pros and Cons of IaaS&lt;/h3&gt;

&lt;p&gt;Infrastructure as a service drastically changed how businesses implement and use technology to scale. Many startups cannot invest or accommodate on-site equipment that allows them to size. Thence, smart entrepreneurs opt for cloud infrastructure and prepare for the future.&lt;/p&gt;

&lt;p&gt;IaaS saves businesses the cost and effort of installing in-house hardware and on-site virtual environment, which makes it ideal for companies looking to share their temporary workload. To put it simply, it provides more flexibility than traditional IT models, as it eliminates the need for onsite data center's usual IT infrastructure demands.&lt;/p&gt;

&lt;p&gt;Apart from flexibility, it offers scalability too. As your business grows, you can scale your IT resources along with it. Conversely, you can scale it down, also, if the situation calls for it.&lt;/p&gt;

&lt;p&gt;IaaS might not be the best fit for you if you have already invested in on-premises infrastructure, or if you have a team of IT experts at your disposal, and don’t require additional manpower. In the long run, renting will add up to a sizable amount of costs; costs which you could save if you opt for an IaaS platform.&lt;/p&gt;

&lt;h3&gt;Which Companies Operate on IaaS&lt;/h3&gt;

&lt;p&gt;Many famous industry titans run on IaaS. Some of the honorable mentions are:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Google Cloud Engine&lt;/li&gt;
&lt;li&gt;Microsoft Azure&lt;/li&gt;
&lt;li&gt;IBM cloud&lt;/li&gt;
&lt;li&gt;Amazon Web Services&lt;/li&gt;
&lt;li&gt;Rackspace&lt;/li&gt;
&lt;li&gt;Verizon Enterprise&lt;/li&gt;
&lt;li&gt;Oracle cloud&lt;/li&gt;
&lt;li&gt;VMware&lt;/li&gt;
&lt;li&gt;Adobe&lt;/li&gt;
&lt;li&gt;Phoenix NAP&lt;/li&gt;
&lt;li&gt;Red Hat&lt;/li&gt;
&lt;li&gt;Kamatera&lt;/li&gt;
&lt;li&gt;IaaS Security&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;The primary focus of this model is to manage virtual machines. The priority of a chief security officer is to overlay an administrative framework and allow the organization to put controls in place and assist in avoiding open access and potential costly wastage.&lt;/p&gt;

&lt;h3&gt;When to use IaaS&lt;/h3&gt;

&lt;p&gt;Whether you’re a startup or a business giant and need a “pay-as-you-go” model of cloud computing, IaaS is for you. If you’re trying to scale up your business while keeping an eye on your expenses, or if you have a vast amount of data that needs processing and storage, you can count on IaaS to do precisely that for you.&lt;/p&gt;

&lt;p&gt;If you’re worried about your in-house infrastructure suffering from a disaster and data loss, you can put your mind at ease, knowing your data is not on the website but a remote data center. Also, IaaS services include networking, which you can benefit significantly from.&lt;/p&gt;

&lt;p&gt;You can contrast IaaS vs. PaaS, in the fact that it is a rudimentary model of cloud computing. The vendors provide servers, storage, and networks while the responsibility of managing applications, servers, data, middleware, and operating systems falls squarely on your shoulders.&lt;/p&gt;

&lt;p&gt;Essentially, you’re purchasing physical hardware and virtual resources, you have to install your OS on it, and on top of that, the web applications you need to deploy.&lt;/p&gt;

&lt;h2&gt;What is PaaS?&lt;/h2&gt;

&lt;p&gt;Platform as a Service or PaaS is a model where the vendor handles the hardware, databases (where all your data is stored), and the environment required to run your web application. You simply provide them with your developed web application and data, and then they deploy the app for you.&lt;/p&gt;

&lt;p&gt;This model might be the right choice for you if your business entails custom web applications. Besides, installing, running, and maintaining the infrastructure won’t be your headache. Still, the third-party’s, leaving you free to focus solely on application development while PaaS services take care of the rest.&lt;/p&gt;

&lt;h4&gt;Pros of PaaS&lt;/h4&gt;

&lt;ul&gt;
&lt;li&gt;Convenient and easy-to-use&lt;/li&gt;
&lt;li&gt;Cloud Infrastructure accessibility from any web browser.&lt;/li&gt;
&lt;li&gt;Eliminates the need for in-house hardware installation&lt;/li&gt;
&lt;li&gt;Cost-effective model due to the Pay-As-You-Go model.&lt;/li&gt;

&lt;/ul&gt;

&lt;h4&gt;Cons of PaaS &lt;/h4&gt;

&lt;ul&gt;
&lt;li&gt;Lacks resilience because if unfortunately, the IaaS infrastructure gets disrupted or faces an outage, it causes hiccups in productivity and services. &lt;/li&gt;
&lt;li&gt;Ideal cloud PaaS services providers can leave you feeling frustrated. To make PaaS worth your while, you need good speed, reliability, and support, or else it can become costly.&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;Best PaaS Providers&lt;/h2&gt;

&lt;p&gt;Now that you’re aware of what is PaaS and if you find this model attractive and viable, several popular vendors offer Platform as a Service infrastructure. For instance:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;a href="https://wwww.cloudways.com"&gt;Cloudways&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Cloud Oracle &lt;/li&gt;
&lt;li&gt;Google Cloud Services &lt;/li&gt;
&lt;li&gt;Microsoft Azure &lt;/li&gt;
&lt;li&gt;Amazon Web Services &lt;/li&gt;
&lt;li&gt;SalesForce &lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;These are some well-known and reputable vendors who offer free trials of their PaaS services so they can ensure that you’re choosing the right vendor.&lt;/p&gt;

&lt;h2&gt; PaaS Security &lt;/h2&gt;

&lt;p&gt;This model primarily focuses on protecting the data. This is significantly important in the case of storage as a service. An essential element to consider within this model is the ability to plan against the possibility of an outage from a cloud infrastructure provider.&lt;/p&gt;

&lt;p&gt;Another ability to consider is the encryption of data while it is stored on a third-party platform, and to be aware of the regulatory issues that may apply to data available in different parts of the world.&lt;/p&gt;

&lt;h2&gt;Why PaaS?&lt;/h2&gt;

&lt;p&gt;If you want to scale your business, or if you need to develop and run web applications but don’t want to break your bank, setting up backend software and hardware infrastructure, and take on the whole responsibility for it, you can opt for PaaS cloud services.&lt;/p&gt;

&lt;p&gt;Also, if you want your developers to focus on building applications and not on running security patches, for instance, it’s time you start using PaaS. It will save you cost, effort, and time.&lt;/p&gt;

&lt;h2&gt;What to look for in a Cloud-based Infrastructure?&lt;/h2&gt;

&lt;p&gt;You must take into account the number of visits to your website every day – the traffic – and opt for the processing power and storage, best suited to the amount of traffic your website receives. If it’s not suited to the amount of traffic, either it’ll crash due to lack of processing power needed to serve too many visitors, or you’ll choose an extensive cloud infrastructure when your site traffic is relatively low, and that’ll put a dent in your wallet. The other two factors that you should take into consideration before choosing your cloud provider are downtime and migration.&lt;/p&gt;

&lt;h2&gt; By and large, &lt;/h2&gt;

&lt;p&gt;To wrap this post up, if you want to keep up with the changing standards, you must invest in cloud computing. Not only will it help you serve your customers better, but it will also help your business grow.&lt;/p&gt;

&lt;p&gt;It will iron out the kinks and limitations traditional IT infrastructures pose. Once you’ve decided on that, you can choose whether you must opt for IaaS or PaaS, depending on how you wish to run your cloud-based applications.&lt;/p&gt;

      <description>&lt;p&gt;Cloud hosting has become the gold standard of hosting solutions these days. All popular ecommerce stores, such as Snapdeal, Alibaba, and Amazon, runs on cloud hosting solutions.&lt;/p&gt;

&lt;p&gt;In this article, I will demonstrate why AWS ecommerce solutions are leading the market and why AWS is the best for mid-level and high-traffic stores.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;The Impact of Hosting on Ecommerce Success
Just ten years ago, when ecommerce store owners went shopping for a hosting solution, their prime considerations were traffic load management and affordability. This was one of the reasons why ecommerce stores started with shared hosting solutions (the price factor) and then upgraded to Virtual Private Servers (VPS) to deal with growing traffic load. This used to be the typical journey of ecommerce stores.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Time has evolved, and now the competition in the ecommerce industry has heated up. Hosting solution that powers the store has become a decisive edge. To deal with the competition, the selection criteria for hosting solution has changed to reflect the current situation. In particular, the factors that affect the selection of a specific hosting solution include the following pointers.&lt;/p&gt;

&lt;p&gt;i. Server Uptime&lt;br&gt;
In the ecommerce industry, downtime directly translates into a loss in revenue and customers. This is why uptime is often the first factor when selecting the hosting provider for an ecommerce store.&lt;/p&gt;

&lt;p&gt;ii. Scalable Resources&lt;br&gt;
During the Holiday Season, all ecommerce stores experience a significant increase in traffic and user requests. This significantly increases the demands for server resources (RAM, Bandwidth, and Storage). As such, a hosting solution that offers scalable server resources is ideal for ecommerce stores.&lt;/p&gt;

&lt;p&gt;iii. Simple Backup Processes&lt;br&gt;
Ecommerce store owners know that the most critical asset in their store is the product and customer data. Thus, server backup processes that provide both automated and on-demand backups with onsite and off-site storage are an essential component of store management and disaster response strategies.&lt;/p&gt;

&lt;p&gt;iv. Extendible Platform&lt;br&gt;
Digital marketing for ecommerce stores now requires the use of a host of native and third-party tools. Several tool categories, such as performance measurement tools, email marketing, and social media management tools and CRM (Customer Relationship Management), have become integral to store operations. A hosting solution that supports the problem-free integration of these tools is always preferred over the competitors.&lt;/p&gt;

&lt;p&gt;v. Pay for Consumption Billing&lt;br&gt;
Running an ecommerce store can get costly. The popular payment model for ecommerce hosting used to be fixed monthly installments, regardless of the level of consumption of server resources. However, many store owners now prefer the pay to consume model in which they only have to pay for the resources they consume. This simplifies the billing cycles and allows ecommerce stores to remain viable during the downtime.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;How AWS Ecommerce Solutions Are Taking over the World
Popular retailers and ecommerce stores such as Nordstorm, Instacart, and Snapdeal host their core applications on AWS ecommerce architecture. Since Amazon Web Service (AWS) is a pioneer in the cloud industry, it hosts several favored brands, including Unilever and Airbnb.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;The most important reason behind this decision is the robust architecture that ensures that the ecommerce stores can leverage the AWS platform’s reliability to interact with the visitors and achieve the sales target. Additionally, the ability to scale server resources in minutes and (almost) unbeatable multi-level AWS security offers ecommerce stores a robust and globally-compatible infrastructure that is second to none.&lt;/p&gt;

&lt;p&gt;AWS platform has the benefit of improving its ecommerce architecture and services in the light of the experiences of operating Amazon, the world’s largest ecommerce platform. This has led to the development or several industry-leading technologies that have made AWS ecommerce solution the best ecommerce platform out there.&lt;/p&gt;

&lt;p&gt;To give you a hint of these features that have made AWS ecommerce an awesome solution, let me introduce the Catalog Service that is powered by another innovative technology, NoSQL (a fast and scalable database capable of handling large volumes of traffic by adding in more servers). Every ecommerce store owner understands the importance of a powerful catalog component that is central to store inventory management and related areas.&lt;/p&gt;

&lt;p&gt;As you might have guessed, NoSQL is a popular DBMS that is very popular in a range of domains and application scenarios.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Why Cloud Hosting Is Best for Ecommerce in Contrast to Traditional Hosting
i. Handling Peak Hour Traffic
Ecommerce stores can’t afford to crash during peak season. That where scalability comes in. It helps ecommerce stores deal with a lot of traffic and increase customer activity in a dynamic way. As user activity increases, stores on cloud solution scale up the resources simultaneously to cater to the load.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;ii. No Fear of Losing Data&lt;br&gt;
When files storage is on a physical hard drive, and it gets corrupted, recovery of data is nearly impossible. Such a risk can’t be afforded when it comes to crucial day to day dealings in business operations data. Therefore, by hosting ecommerce business on the cloud, system failures or physical damages will not hurt the daily business operations. Servers will be functional at all times while ensuring smooth customer activity.&lt;/p&gt;

&lt;p&gt;iii. Bandwidth Issue&lt;br&gt;
Cloud-based solutions are perfect for ecommerce businesses that have fluctuating bandwidth requirements. When the bandwidth requirement increases, it is pretty easy to scale up the resources immediately with no fear of slowing the main website/webpage down.&lt;/p&gt;

&lt;p&gt;iv. Reliability&lt;br&gt;
The main driving force for any business in achieving its business goals is almost always teamwork. The same sort of relationship can be seen when we talk about cloud hosting services. When the load is distributed evenly among the cloud server, the website functions at an optimal level. So it’s safe to say that your site has a continuous backup system that can always be used to restore to.&lt;/p&gt;

&lt;p&gt;v. Full Root Access&lt;br&gt;
Cloud hosting provides its users with complete control over their hosting platform. Having full root access means that the user can easily install updates and the latest applications on their server, which ensures smooth operations of their website.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Why Ecommerce Stores Migrate to AWS Ecommerce Platform?
Retailers and Ecommerce stores such as Nordstorm, Instacart, and Snapdeal have migrated to AWS architecture and now have their core applications on Amazon Web Services (AWS) Cloud. There are two reasons for this. The first pertains to staying ahead of the technological curve where in this interconnectivity requires technology to interact, engage, and achieve sales. The second reason is for these brands to opt for more secure, reliable, flexible, and globally compatible infrastructures that let them scale after they migrate to AWS architecture.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Being the pioneer in the cloud computing industry, it now hosts the application of major brands such as Unilever and Airbnb since AWS is the market leader when it comes to the cloud industry, although Google’s GCE hosting and Microsoft Azure have joined the fray to succeed in the race.&lt;/p&gt;

&lt;p&gt;Most service providers by the AWS platform are from the learnings of their Amazon technology team, who have been managing some of the world’s largest ecommerce stores. To give you an example of one of their best work, they designed a NoSQL database technology to develop a very efficient product known as a ‘Catalog Service.’ This Catalog service is the fundamental technology component to power an ecommerce store. If you are wondering what a NoSQL database is and why is it considered an achievement, it's a fast database that is scalable and can handle large amounts of traffic by adding in more servers.&lt;/p&gt;

&lt;p&gt;Just like the way NoSQL technology is embraced by many developers across a wide variety of application domains and uses cases, Similarly AWS ecommerce solution for ecommerce stores and online retail shop is an ideal cloud solution which is embraced by the entire business community because of strong AWS monitoring and security processes.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;What Architecture Does AWS Ecommerce Platform Provide for Ecommerce Applications?
i. Efficient Catalog Service
Effective cataloging is the backbone for any ecommerce store to be successful. Updating the ecommerce regularly with a variety of product catalogs along with the customer base can be a daunting task. On top of all that, the inventory needs to be indexed and searchable. Every individual page should consist of rich information such as customer review, images, and the info of the product which a user desires to seek.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;In an increasingly interconnected digital world, the online demand of a store can reach a new peak through social media awareness, for example, giveaways, offers, or deals. Customers (visiting users) are impatient, and their demand for easy, swift access to the product catalog is increasing daily. Any glitch in performance here can severely impact the reputation of a brand.&lt;/p&gt;

&lt;p&gt;The most important consideration when running an ecommerce business store on cloud services is its robust architecture and application engineering, which allows the computing resources to simultaneously scale up and scale down as per need of the hour to avoid unnecessary billing cost. With this proper auto-scaling feature management, ecommerce store will be able to handle millions of catalog view along with tons of transaction of orders, seamlessly to meet top-line objectives.&lt;/p&gt;

&lt;p&gt;AWS Catalog Indexing&lt;/p&gt;

&lt;p&gt;The needs of the ecommerce business are to get the necessary configurations and architecture. AWS ecommerce platform provides its users with ready-to-use ecommerce architecture and blueprints in the form of AWS Cloud formation templates. These templates are provisioned to highly scalable and available infrastructure for hosting online stores.&lt;/p&gt;

&lt;p&gt;Ecommerce web apps and platform providers such as Magento have noticeably published versions of their software to finetune to AWS architecture and integrate AWS monitoring and security processes.&lt;/p&gt;

&lt;p&gt;With AWS architecture, it’s now a piece of cake to build an ecommerce website with a dynamic product catalog that scales with your business.&lt;/p&gt;

&lt;p&gt;ii. An Innovative Checkout Process&lt;br&gt;
The next critical building block for an ecommerce store is checkout service. Keeping the checkout service in proper order involves many workflows and steps which need to be coordinated. In addition to this, things like the purchase history of a user and credit card transactions are subject to specific regulatory requirements. Above all that, customers now expect their private data such as credit card information, personal information, order history to be kept secure on compliant application stack,  and managed secure infrastructure.&lt;/p&gt;

&lt;p&gt;Keeping these views into consideration and to help ecommerce stores accomplish regulatory compliance and security, AWS security provides secure and certified cloud infrastructure for ecommerce applications. Now, ecommerce store owners get better cloud security of lower layers of the system like storage, compute, and network since AWS allows them to build an application layer over it. It’s, for‌ ‌this‌ ‌reason, AWS security has obtained multiple cloud security certifications relevant to ecommerce business, including the Payment Cards Industry (PCI) and Data Security Standard (DSS), on these lower system layers.&lt;/p&gt;

&lt;p&gt;AWS Security&lt;/p&gt;

&lt;p&gt;When it comes to application-level security of any system built on AWS, as per its Shared Responsibility Model, AWS is not responsible, but, however, AWS does provide many tools to facilitate the enforcement of AWS security best practices protocols. Some of these are audit tools like web-application-firewalls and compliance ‘checkers.&lt;/p&gt;

&lt;p&gt;Also, AWS ensures to regularly publish security best practice documentation based on its customer experience. One can build a secure checkout service which would manage the purchasing workflow from order to fulfillment from the tools AWS provides.&lt;/p&gt;

&lt;p&gt;Though search, catalog, and checkout services are the main building blocks for ecommerce businesses. It is the business logic that differentiates them from one another. To ensure the smooth functioning of the ecommerce store, one has to almost always create a custom software component.&lt;/p&gt;

&lt;p&gt;Additionally, developer-oriented tasks such as server management, and culture is very critical for the ecommerce store as new features are on deployment schedule every day to support the user’s demand and needs.&lt;/p&gt;

&lt;p&gt;AWS offers an ecosystem that places control in the hands of users. They have introduced a mechanism for AWS monitoring of server, which provides essential metrics for infrastructure and ecommerce applications. They have access to a foundation that opens up pathways to apps and websites. AWS for ecommerce stores provides users with the flexibility of accommodating configurations to achieve these business milestones.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Migrating to Managed Cloud Hosting for AWS
Though search, catalog, and checkout services are the main building blocks for e-commerce businesses. It is the business logic that differentiates them from one another. To ensure the smooth functioning of the ecommerce store, one has to almost always create a custom software component.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Although AWS offers an ecosystem that places control in the hands of users and they have access to an infrastructure that opens up pathways to applications and websites. Still, developer-oriented tasks such as server management, and culture is very critical for the ecommerce store as new features are on deployment schedule every day to support the user’s demand and needs.&lt;/p&gt;

&lt;p&gt;Store owner hires in-house DevOps team to manage server related issues, with the hope of investing more time on marketing activities. However, gradually, they realize the inhouse team does not justify ROI (Return on investment) as when compared to outsourcing it to an agency. However, there is always a fear of credential leaks and private data sharing. To address these concerns, store owners go for migrating their ecommerce applications to managed AWS Cloud hosting.&lt;/p&gt;

&lt;p&gt;Managed AWS Cloud hosting makes life easy for many ecommerce store owners who don’t have or can’t afford in-house DevOps teams to manage their servers. By migration to managed AWS cloud, ecommerce store owners outsource the most technical aspect of server management while improving site performance and security.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Managed Hosting Simplifies Your Ecommerce Projects
Third-party providers build an infrastructure on top of AWS, making it easier for the user to run operational tasks. Furthermore, this removes complexities of directly dealing with AWS Ecommerce architecture as the outsourced development team handles this.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Services like these assist most of AWS operations such as server creation, server security, and everything in between. In most cases, server providers also specialize in web applications like WordPress, Magento, and Larval for their customers.&lt;/p&gt;

&lt;p&gt;Cloudways, a managed AWS Cloud Platform, makes AWS for ecommerce store owners a piece of cake. Store owners can easily set up the server and deploy their favorite ecommerce applications such as Magento or WooCommerce easily within few minutes. Cloudways makes sure that store owners don’t get their hands dirty with server management. Therefore, they are provided with managed UI Interface to perform a server-level operation such as to install SSL, Varnish, etc.&lt;/p&gt;

&lt;p&gt;&lt;a href="https://www.cloudways.com/en/amazon-cloud-hosting.php"&gt;AWS Managed hosting&lt;/a&gt; is a simple process of setting up the server and deploying a suitable web application within a few minutes. However, it’s important to note that the customer using the managed AWS ecommerce solution may not directly deal with the server but instead interacts with a custom browser or software-based interface to perform server-level operations.&lt;/p&gt;

&lt;p&gt;The third-party provider continues to put forth feature-rich tools, plugins, caches, syscaches, and database options that continuously improve the website’s experience for the visitor. Apart from that, the third party is also partially responsible for the security of the server. Though this may not be directly their responsibility, however, to ensure that the business keeps running, they continue to offer AWS security features to give their customers a sense of protection from frequent cyber attacks. These tools include Intruder Detection System (IDS), firewalls, and other related functions.&lt;/p&gt;

&lt;p&gt;All in all, these third-party providers aim to give their customers a rich experience of running their business without losing out on much time.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Conclusion
AWS ecommerce provides security, universal, scalable infrastructure, and core features to online retail companies that they can then work on. As the company sales increase and growth milestones are completed, the AWS infrastructure provides more scalable features.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Similar to AWS ecommerce architecture. Cloudways also provides a clutter-free experience for the server owner. Sometimes, it gets too complicated to run a simple task, so with a premium, Cloudways reduces the clutter and makes it easy to run most operations that AWS’s platform also provides. Furthermore, they have a technical team available round the clock to help in case of any complications.&lt;/p&gt;
