Deploying An Ubuntu Image with Nginx Server in Amazon EC2 Instance.

Joseph Igwe — Thu, 08 Feb 2024 04:18:13 +0000

Amazon EC2 instance is an Infrastruture as a Service(Iaas) in the cloud computing model. Amazon Elastic Compute provides resizeable compute capacity in the cloud. EC2 allows users to rent virtual machines, known as instances, and run applications on them.

These instances are available in various configurations, allowing users to choose the amount of virtual CPUs, memory, storage, and networking capacity that best suits their needs.

In the next few steps we will deploy an Ubuntu instance in EC2 ,and install nginx server.

PREREQUISITES:

To start ,we will need an aws account www.aws.amazon.com.
Secondly is a Webterminal,for example GitBash in this exercise.
STEPS
1 Log into your console , on the search panel above type ec2 and select it from the drop-down menu.

2 In the window that opens after step 1 , select Launch Instance.

3 Provide a unique name for your EC2 virtual machine Hagital,in the name and Tag section.

4 In the Application And OS Images,click on the browse more AMI and type Ubuntu in the search window.

5 Scroll down and select "Ubuntu Server 22.04 LTS (HVM), SSD Volume Type"

6 Scroll down , in the instance type leave as default t2.micro free tier as shown .

7 Scroll down to key pair login section,and select create a new key pair. We will create a key pair to grant us access when we try SSH into th machine from our web terminal.

8 Provide a unique name for the key,and leave the remaining settings as default. Click on the create key button below. Your unique private key will download into your host machine.

9 In the Networking Settings, leave default to create security group selected.Select all checkboxes to "Allow SSh from","Allow HTTPS traffic from the Internet" , and "Allow HTTP traffic from the Internet".

10 We leave all other setting as default and click on the lauch Instance button to create the machine.

If suucessfully launched, we get the below message

USING A WEB TERMINAL TO ACCESS THE EC2 INSTANCE AND CREATING A WEBSERVER(nginx)

1 Click the hamburger icon on the left and select Instance. Select the instance created and it opens to a new window.

2 In the new window,click and select connect

3 We can connect using EC2 instance manager,Session Manager,SSH clent or EC2 serial console. we are using SSh client to connect.Select SSH client and follow the below steps to connect.

4 Open GitBash web terminal,and locate your private key downloaded ealier in the exercise. using the commant cd

. Our is located at the download folder.

5 Run this command, if necessary, to ensure your key is not publicly viewable.
chmod 400 "hagital-key-pair.pem"

6 Connect using the command below into your instance "ssh -i "hagital-key-pair.pem" ubuntu@ec2-3-85-111-48.compute-1.amazonaws.com"

CONFIGURE NGINX WEBSERVER
1 run the command sudo su to get admin access
2 run apt update to upgrade the instance.

3 Install Nginx using the command apt install nginx.When prompted type yes and continue.

4 Verify the Ip address of your machine using the command :"Ip addr"

5
Copy the Ip Address an paste in a browser the see your newly created webserver.

In conclusion , Amazon Ec2 is widely used for various purposes including hosting of websites,running applications,processing data and more. It forms a fundamental building block of many AWS solutions and is a vital solution.

Creating A Function App In Azure, Pushing to GitHub and formatting Readme using VS code.

Joseph Igwe — Sat, 15 Jul 2023 16:54:17 +0000

Azure Function is a serverless platform as a service (PaaS) in Azure that runs small, single-task code without requiring new infrastructure to be spurn up.

To understand it better, I will define what a serverless is , it is a cloud computing execution model in which the cloud provider allocates machine resources on demand taking care of servers on behalf of their customers.

In this guide we need to know some basic definition to provide us with a foundation to understanding what a function app is in azure, we will be covering the below mentioned objectives

Creating a Function App in Azure.
Using Visual studio to create a simple calculator App
Testing the Calculator App and on our web browser
Pushing files to GitHub and formatting our ReadMe to be readable.

Steps to Create A Functional App in Azure.

Sign up to Azure or login if you already have an existing account.
On the search bar, type "Function App", and select funtion app from the listed services below. Then create.
On the window that opens, in the basic task pane select an existing subscription, resource group or create a new one, if no resource group exists.
In the instance details, provide a name for the function app Leave radio button code selected as default. in the do you want to deploy code or container? 5.scroll down ,under Runtime stack click the drop down button and select .NET
for operating system, leave window as default.
For Hosting consumption model is selected.
Click the Review+ create button below.
Click create button
When the deployment is complete click on the open resource button.

Steps To Creating A Calculator App Using Visual studio

Steps

Launch Visual studio from your local machine. At the right pane, select create a new project.
In the search bar type "Azure function", or select from the list below and click on the Next button below.
In the window that opens next, give the azure function a Project name. Then click the create button below.
In the window that opens, select HTTP trigger. At the right pane select the storage account dropdown button, select browse
An azure storage account appears, create a new one on the existing subscription and click ok.
click the create button.

We can see above that we have successfully created our Function App in visual studio. We will start the process to coding our simple calculator app that is triggered on the browser.

Coding the Calculator App

To code the calculator app, we follow the below steps

In line 15,Function App name change it to "JoeCalcFunctApp".
Delete from line 22, to line 30. 3.Enter code as shown below to build a simple calculator app.
At the right pane, Right click on the Calculator function app created and select Build from the options.
Our Calculator Function app was built successfully. Publishing Our Function App to Azure

To publishing our calculator app to azure, follow the following steps below.

At the right pane, Right click on the Calculator function app created and select publish from the options.
In the Publish target, select Azure and click Next.
In the "Publish specific target" ,select Azure function(windows), and click next. 4.In the function Instance window, your existing subscription name will be shown, for group leave as default, then for the function app, click the folder with an arrow in front, in the drop down select your function app created in azure. Finally click the finish button below.
The next window that appears its the ready to publish window, if satisfied click the publish button.
When the publish button is clicked , the function has been successfully published to azure cloud.

Testing Your Function App on The Browser.

Alright its been an amazing journey so far, we are now going to test our calculator app on our browser to ensure its working properly. Follow this steps below to achieve this process.

Open the Azure portal and select function app from the home screen.
At the left pane, scroll down to Function and select. We can see the calculator app created.
Click the App to open it and copy the get function URL.
On a browser address bar paste the copied URL. 5.The above window shows "this page is not working". To test our code at the end of the pasted URL, after "==", type &x=n&y=n. Note: n is an integer.

Pushing Files To GitHub and formatting Readme

In the below steps i will guide you on how to push our calculator application to GitHub and format our files in human readable format.
We are required to have an existing GitHub account to do this successfully.

Login into your GitHub account, on the dashboard click on new
In the create repository window , give your file a name and below ,make sure the add a Readme file is selected.
Click the create repository button below.
On the azure portal ,select the Calculator function application, on the left pane, scroll down to Deployment, select deployment center.
In the Source, click the drop-down arrow and select** GitHub** from the options provided, then click the Authorize button.
In the next window, an authorization window opens, click on the Authorize Azure App services button below.
Enter your password and click on the confirm button.
The Function App opens a second time, your GitHub username is shown by default. In the Repository, click the drop-down arrow and select the function app deployed. For Branch, select Main , and click on the save button above.
Clicking the notification button above it shows that GitHub setting up and deployment was completed.
On the Function app on GitHub account, open main and click to see our deployed . Alright, we are done with the deployment of our Application from Azure to GitHub, next we proceed to formatting our GitHub to be human readable.

CREATING LINUX MACHINE IN AZURE PORTAL

Joseph Igwe — Sun, 02 Jul 2023 15:49:09 +0000

The steps above can be used to create our Linux Virtual Machine but with slightly different variation. We can proceed to creating our machines using SSH or Password. In this guide I will show creating your VM using only Password. To start follow the steps below.

1 Select 'create a resource' as shown in the example above.

2 From the Create a resource window, select virtual machine.

3 Follow the steps stated while creating a windows machine as above for subscription, availability options, resource group and Image. Provide a name for your machine. Here we are using 'azurelinux01' as virtual machine name.

4 Just as we did in creating our Windows VM earlier, our Linux VM would be given a Username and password. these details will be required when login into the created machine. The port selected is SSH 22.

5 We leave others menu items as default, now we move to the Monitoring menu, under diagnostics and disable it. We are doing it just for this practical only.

6 In this step we select the 'Review create button'. We wait until we get validation passed. Once validation passed, click on create button.

7 In this step, we are done creating our VM, what is seen is Deployment complete. Next, select the 'go to resources' button.

8 in this step we proceed to increase our public ip timeout to prevent the VM from timing out, here we select it to be 30 minutes. Then save changes.

9 After we proceed by selecting our Linux VM machine created.

10 select connect, take note of the connection instructions, open windows power shell or any terminal of your choice.

11 Here we are using MobaXterm as our terminal. use ssh Azureuser@20.106.237.88 to connect.

12 provide your password, don't worry if you cant see it as you type, proceed.
13 your Linux VM is now ready.

it is recommended as a rule of thumb to always delete resources not in use. The cloud is expensive, and you cannot leave resources running unused. To delete this VM proceed as follow.
Steps to Delete Linux VM
1 On the Linux vM home page ,select delete among the menu listed

2 then proceed to selects the different resources created and ticks all boxes, finally select delete.

We have covered a lot of important things you need to know in this practical, if you find it interesting, please share your comments below.

Creating Azure Web App using CLI

Joseph Igwe — Sun, 02 Jul 2023 08:02:28 +0000

in this blog spot we will create a web app in Azure using the command line interface. According to Wikipedia definition ,azure web app is a cloud computing based platform for hosting websites, created and operated by Microsoft. It is platform as a service which allows publishing Web Apps running on multiple frameworks and written in different programming languages, including Microsoft propriety ones and 3rd party ones.

Things Required

Install Azure CLI
GitHub Account
Install Git Bash

Follow the steps below to get started

On your windows machine open PowerShell
To login into your Azure account type az login and press ENTER

Create A Resource group using the command az group create --name ( group name) --location (region)

Create a web app service plan using the command appservice plan create --name(plan name) --resource-group (resource group name)

Create a web App next using the below command az webapp create --name (name of your webapp) --resource-group (resource group name) --plan (name of plan created already)

STEPS TO DEPLOY WEB APP

Go to your Git Hub account ,and click on the repository that contains your website files(HTML, CSS, JavaScript)
Click on the Code and copy the URL,HTTPS is selected by default, copy it.

3 Go back to PowerShell and type the following command

az webapp deployment source config --name "webApp name" --resource-group "resource group name" --repo-url "url copied from GitHub" --branch "branch of the repo" --manual-integration

In this case we are using webapp name of "pluralsite", resource-group name "Buchiw", repo-url "The copied url from your GitHub above", and branch "master".

Go to your Azure portal and open your resource group, then App service plan, under settings select the Apps . select and click the App created,"pluralsite".

The web app gives us an overview of

From the above created web app, label1 is the resource group containers where all the services and resource are stored, label2 is the default domain, the URL of your website and label3 is the Repository from GitHub. It holds every content of your websites.
Clicking on Deployment centre at rightside under Deployment gives you a summary of your entire page

We can also view our web page by copying and pasting the domain name on our browser.

SCALEUP AND SCALEOUT
Scalability is the ability to quickly and easily increase or decrease the size or power of an IT solution or resources
Vertical scaling or scaling up or down is used when we need to react quickly to fix performance issues that cannot be resolved using classic database optimization techniques. It involves adding more RAM and Storage.

Horizontal scaling or scaling out or in, it involves you adding more databases or divide your large database into small pieces using a partitioning technology called sharding. Sharding is separating different rows of information from table and storing them in different databases. It is used in most notably non-relational No SQL databases. It enables them to handle large indeterminate and rapidly changing data.

STEPS TO SCALE UP

Go to on app service plan,
under settings click on scale up, choose a desired capacity from Production, the next window shows you a confirmation window to confirm your selection.

SCALE OUT

Go to the App service plan page,
Under setting select scale out. In the Scale out, we have Pricing plan and Scaling options. In pricing plan you can select from a range of different prices. For Dev/Test(less demanding workload), you may pick from Free F1 to Basic B3, and for Production Standard S1 to Premium V2 P3V2. On the scale out , we can choose manual, automatic or rule based.

In conclusion, as production increases and more and more traffics comes to our websites we will always need to scale up and scale out. I hope you were able to provision your web app following these steps.

Using a Linux machine for beginners.

Joseph Igwe — Fri, 30 Jun 2023 17:44:59 +0000

Linux is an open source operating system, unlike windows, its environment, is constantly being updated by contributors. Developers can easily access the Linux source code for customization. Linux offers a higher degree of security, stability , and require little disk space. It has powerful networking capabilities and gives the user power over the machine. Linux is so popular that Android used on mobile are built on its framework.

In this guide I will show you some of the few basic commands to know to get started.
To begin, you will need to download and install Linux on your workstation. Be reminded that Linux comes in different distributions such as Ubuntu, CentOS, Debian, Fedora, Xubuntu, Arch etc.

1 sudo su - This is the first command that gives you root access over you machine , without it you cannot not run any command on you machine. Depends on the configuration it may require you for password. sudo su

You will see we do not have permissions to install a web server nginx without doing sudo su.

2 apt update - It is used to update the package index files in the system which contains information about available packages and their version. apt update

3 mkdir - The function creates a new empty directory /folder in windows machine, whose name is defined by path. You supply the name as an argument. The rmdir is used to remove directories, only when there is no file inside it. To remove dir classrep,

4 list: This is a very powerful and commonly used command. ls, without any options list files and directories in plain format without displaying much information, like file types, permissions, modified date and time etc. Some of these options includes:

4.1 list in reverse order : ls -r
4.2 To list permission of files and other attributes such as folder name, size and modified date and time. ls -l
4.3 Using this syntax further modifies your listing to become human readable.it becomes easy to understand. ls -lh,To learn more about more,click

5 Print working directory : This command displays the path of the working directory starting from the root. Its a shell in-built command.pwd
Pwd [options]
5.1 "L": Path resolves symbolic link and prints the path of the target
5.2 "P": Displays the actual path without resolving the symbolic link.

6 Creating text files(touch): When we want to create text files , use the command touch file_name'. It is used to creates a file without any content. to create a file with a content, use 'cat command'.
The touch command can also create multiple files in one command

touch file1.txt file2.txt file3.txt

Note
use one space as the separator.

7 concatenate (cat) - This is a very useful command in Linux, it helps us view, create and concatenate files. Concatenate is reading data from file and giving their content as output.
Some useful cat commands are below
7.1 View the content of filename1:

cat file_name1

7.2 This is used to view multiple files:

cat file_1 file_2

7.3View content of a file preceding by number line :

cat -n file_1

7.4 This command creates a new file :

 cat > file_1

In the next graphic we can see how we view content of a file, click the link to learn more

8 copy (cp) - This is the copy command in Linux, used to copy files and directories from one location to another.
cp [source] [destination],to do this navigate to the folder where the file to be copied is located , and specify its filename and the path where it is to be stored.

8.1 copying multiple files - We do this using the command

cp text1.txt text2.txt text3.txt /home/user/destinationfolder/

The above diagram shows us when we are copying the files ,file1txt,file2.txt,file3.txt from their source folder "Businessclass" to destination folder "learn".

9 Change directory cd - This command changes the current working directory to another one specified cd
9.1 changing to previous: Adding a dash(-) returns you to your previous directory. cd -

9.2 Home directory: The absence of the current directory path shows you are at the home directory. Use the command cd to go to home, also when you use the command cd ~ it takes you to the home directory.

As you see above there is no path. Using cd ~ does the same thing as above.

We can use the cd command to do a lot in Linux workspace
10** exit** : It takes a parameter[N], and return the status as [N], if it is not provided, it returns back to its previous status.

File Editors in Linux
We have many text editors in Linux like vi, vim, GNU Nano, gEdit and more. In this exercise we will focus on using vi.

To create and edit a file using vi

On your machine follow this step
1 type vi filename , It opens a file with the name specified or creates a new file .

2 Press i on your keyboard to start editing ,

3 After editing Press ESC to exit insert mode.
Then use “:wq!” to save and exit editor or “:q!” to exit editor without saving.
Using vi to create a text file and saved in a folder Hagital
1 Create the directory "Hagital" with mkdir command.

Creating an Azure resource, using Azure Resource Manager(ARM).

Joseph Igwe — Thu, 29 Jun 2023 11:49:31 +0000

...A fast and easy route to start your journey in Azure.

In this guide I will show you one of the fastest and easy methods to use when creating new resources in azure in less than a minute! don't fret!

I mean its just a finger-tip away. Azure Resource Manager (ARM) is an azure service you can use to manage and deploy resources using Infrastructure as a code paradigm. it enables you to modify and delete resources using a variety of resources including access control, tags, and locks, in azure management.

From Microsoft documentations, we know that with move to the cloud, many teams have adopted agile development methods ,these team iterate quickly they need to repeated deploy their solution to the cloud.

Why choose ARM template

Declarative syntax - It gives you the ability to create and deploy an entire azure infrastructure (virtual machine, network infrastructure, storage in one command.
Repeatable Results - in your development lifecycle ,you need to deploy resources consistently is vital. You develop one template that represents your required state and use it multiple times.
Built-in -validation - Your template is deployed only after meeting required metrics.
Security - ARM is secured, you can use a variety of security features with your resources such as role based access controls(RBAC) and OAuth authentication.

Getting started to creating an azure database using ARM...

Create an azure account ,and login using your email and password
In the search bar type "azure template", select "Deploy a custom template".

In the window that opens, you can create your own template using the editor, but in this exercise ,from the common templates choose creating an SQL database

In provisioning a Database, in the project details choose a subscription, resource group or create a new one. Under instance details, choose a region, and provide a username and password. Continue to the next page "Review+create".

Wait for some seconds, If "validation passed" is shown, then select the "create button".

Wait for the Deployment in Progress process to complete, here the machine is setting up your environment. Once done , select Go to resource icon below.

We have successfully created our database in azure using ARM. Its as quickly and fast.

Finally always remember to delete resources created after use in azure to save cost, unless they are for production environments.

Step to delete Created resources

One of the fastest way is to delete the resource group that service is created on. A second way is to delete the resources individually.
to delete without affecting the resource group, firstly the name box, all the resources under it becomes highlighted and selected.
Select, delete at far right corner

then type delete in the box provide, or you can remove items selected if you want, finally
press delete,a warning pops up.

Thank you for reading, I hope you found this manual helpful as you continue to learn more about cloud services.

Adding Data Disk To Your Vitual Machine

Joseph Igwe — Sun, 18 Jun 2023 15:24:00 +0000

Azure virtual machine comes by default, comes with as OS Disk when created, but this provisioned disk cannot hold storage apart from the Image (Operating system) installed on it. To expand this storage and make it ready for production we need to add a new disk, data disk. In summary, picture an on premises physical disk sitting on your server, but virtualized. In azure available disks are ultra disks, premium solid-state drives (SSD), standard solid-state drives (SSD), and standard hard disk drives (HDD).
In the below guides, we are guided on how to get started...
1 Create a windows 11 virtual machine, follow the link highlighted to get started.
2 On the left side pane, under settings, click on "Disk". A new window opens, under data disks click the "Create and attach disk button" to start.

3 Provide a name, for the new disk, we are going to select a "standard disk SSD", under storage type, for this experiment, but it's recommended to use premium for a production environment. Then click the save, button.

4 Now our data disk has been created successfully as shown below.

5 Click the connect button, at the left side-pane, then download RDP to gain access to your Virtual machine. Open the downloaded RDP file and put your username and Password as used while creating the VM.

6 In the virtual machine, right-click on the window icon, and select and open disk management.

7 As seen above we can see "disk2", the new created disk. Select ok and continue.

8 Right-click on "disk2" and select "new simple volume".

9 Continue clicking next, leave as default. When at the "Format Partition" window, format this volume button is selected by default. Choose a volume name, allocation size, and file system as it is suitable to your needs.
Note: We are changing the default name to "disk2" for this experiment.

10 the next window shows, an overview of what we have done, when satisfied select and click finish button.

11 Finally, our data disk has been created as seen below and ready for deployment.

As a rule of thumb, remember to delete every resource created after usage to minimize on cost except they are very important. Please leave your comments below.

Creating Azure Blob Storage: What you need to know to get started

Joseph Igwe — Fri, 16 Jun 2023 03:56:03 +0000

The Azure storage platform is Microsoft answer to modern data storage on the cloud. its highly available, scalable, durable and secure storage for a variety of storages in the cloud. Imagine yourself coming home from the grocery store and you need to store food items in your kitchen, you will need to separate items based on their nature, some in the fridge, others in open spaces. Azure cloud storage are accessible from anywhere in the world over HTTP or HTTPS or REST API.

Azure blob storage is a massively scalable object store for text and binary data. For example, photos, documents, videos or software can be stored into it. Other Azure storage includes:
Azure files, Queues, Tables, Elastic SAN and Managed disks.
In the following steps we will create our Blob storage and explain the different tier options in Blob storage.
1 Prerequisite
2 Create your storage account.
3 Explain tiers in blob.

To get started you are required to open one of the different accounts provided to start you journey in Microsoft Azure.

Creating Your storage account
Sign into your account on Azure portal and search for "storage account"

2 On the storage account click "create", it brings up the "Basic" page.
3 In project detail, choose a "Subscription".
4 Click on "Create new" or choose an existing Resurce group.

4 Next, Instance details, select a unique name for "storage account name", select a Region where your storage account should be deployed.
5 Select "standard" for performance option and, for redundancy we use "Geo-Redundant-Storage" (GRS). it stores your data in two regions, first the primary region, and a secondary for redundancy.

6 Click "Advanced", next, scroll down to Blob storage section, pick "hot" to always access your data at all times.

7 Next, Networking, under network connectivity, select "Enable public access for all networks."

8 Scroll down, network routing, leave the "Routing preference" as default.

9 Next, Data Protection, we leave it at its default.

10 Next, Review, the click create.

After we have clicked "create" we wait for the deployment to complete and once done click on the "Go to resource" button to view our storage created.

A storage account is more like an empty space, we need to create compartments inside it called containers to store our files. Follow this step to create a container and a Blob storage that can hold our non-binary data.

Creating A Container And Blob storage

1 Inside the storage account, at the left pane, under Data storage, select "container."

2 in the window that opens, select "+Container", a right pane opens, input a unique name, and under public access level, click the drop-down arrow and select Blob.

3 We have created our container successfully; next we are going to upload a file into it.

4 Select the created container, click to open it.

4 Click on the Upload button at the top, a right panel window opens, click the browse for a file button, from your local computer select a file to upload.

5 After uploading the file, we proceed to copy the url of the file and paste on the browser to see it.

Access Tiers in Azure Storage

In Azure storage services, we have three (3) different tiers of storage, Hot, Cool, and Archive.
Hot tier
It is optimized for storing data that requires frequent access, it has higher access cost but lower storage costs.

Cold tier
Data in the cool and cold tiers has slightly lower availability but offer the same higher durability. Data stored for a minimum of 90 days.it has lowest storage cost and higher access cost.

Archive tier
An offline tier optimized for storing data that is rarely accessed. and has flexible latency requirements, on the order of hours. Data in the archive tier should be stored for a minimum of 180 days.

Steps to create azure virtual machine for windows on the portal.

Joseph Igwe — Tue, 13 Jun 2023 04:42:14 +0000

Azure virtual machine offers users to create their own office space on the go. its highly secured, offers developers a quick and easy way to create a computer with specific configurations required to code and test an application. Following these steps creates a Linux,and windows virtual machine.

CREATING AZURE WINDOWS VIRTUAL MACHINE.
1 login to azure website www.portal.azure.com create an account

2 Select create a resource.

3 From the Create a resource window, select virtual machine.

4 The next window that opens is the create a virtual machine. In Basic Menu bar, highlighted, these are some sections under it.
