Cloud Computing 101: Master the Fundamentals

Why become a cloud engineer?

The first and biggest reason is how quickly you can pick up cloud computing with a software background.

If you’re already a developer, you’re already halfway there. Going from software development to cloud engineering is only a slight pivot in terms of skills. In fact, many job offerings have overlaps between software and the cloud. If you are proficient in Java, Python, or SQL, you already fit a large portion of the hiring requirements for this position.

What's the market like?

This is the second reason: the demand for cloud engineers is big and only getting bigger.
Cloud usage is on the rise meaning there are more job openings and security for cloud-capable engineers. The whole field of Cloud is opening and expanding.

In a recent Burning Glass survey, “Cloud Computing” ranked as the most requested skill for tech/development positions, appearing in over 90 thousand job listings - that’s more requested than both “Python ” and “Java” skills combined! This marks cloud computing as the best skill to increase your hireability in the modern tech climate.

This spike in demand has led to some very appealing salaries. According to Glassdoor’s most recent survey, Cloud Engineers across the industry make on average nearly $130k per year, about $40k more than Senior Software Developers.

Solve real-world problems

On top of the market demand for cloud engineers, it’s also an exciting and fulfilling field. Cloud engineers get to solve real-world problems that affect people around the world.

Some cloud engineers work with large companies on security, storage, and accessibility, while others improve the daily lives of day-to-day people. In fact, cloud engineers are a huge contributor to the ease and accessibility of work-from-home lockdowns, making our world safer for people of diverse lifestyles.

On top of that, cloud computing involves creative and varied skills that branch off of software development. A job in cloud engineering utilizes skills in DevOps, web security, disaster recovery, containerization, networking, machine learning, and system design. You won’t be stuck in one domain and can explore the diverse facets of the cloud as a whole.

What types of jobs are there

Cloud engineering jobs generally fit into one of three categories Cloud Architecture, Cloud Development, and Cloud Support. Below we’ll go through each category in depth.

Cloud Architecture

These are big-picture engineers that oversee large portions of a cloud network. Positions in this category deal with the planning and management of all cloud components, including hardware, software, or applications. If a company wishes to expand its services, the architect is in charge of deciding what services are needed to meet the company’s needs. They also evaluate cloud performance regularly and develop technical solutions to overcome challenges from any of the cloud’s components that interfere with cloud usage.

Cloud Architect is the broad title for an engineer in this category. Salaries in this role average $107k per year.

Cloud Development

These programming jobs focus on developing the cloud architect’s vision into code on their respective platforms. They combine traditional development skills with cloud-specific knowledge to build, deploy, and optimize applications through the cloud. Cloud developers get to use their traditional software development skills alongside computer networking, app development, UI, and UX, amongst others

Some job titles in this category would be:

  • Cloud Engineer, $128k annually
  • Cloud Developer, $98k annually
  • Cloud Software Developer, $76k annually

Cloud Support

This is a more service-related category, and the actual jobs tend to vary more than the others. These jobs involve working directly with cloud clients to help meet their needs and maintain individual cloud components. In cloud support, you get to be an expert on a specific cloud technology or hosting service and work with clients to ensure their success. Some cloud support positions also get to explore new technologies and troubleshoot solutions alongside cloud architects to resolve customer issues on a larger scale.

Some job titles in the category would be:

  • Cloud Support Engineer, $55k annually
  • Cloud Security Engineer, $97k annually
  • Cloud Systems Technician, $45k annually

What are the most popular cloud providers and platforms?

There are many companies that provide cloud services for SaaS, PaaS, IaaS. Despite this, the world of cloud computing is generally run by a small group of cloud providers or services that host data. The cloud provider and platform you work with depends on the company you work for, with the most common being Amazon with AWS, Microsoft with Azure, and Google with the Google Cloud Platform.

Below you’ll find the cloud market share for each company, what their platform does well, and some notable companies that use the platform.

Necessary topics to learn for cloud engineers

Now we know the basic steps you’ll need to take to become a cloud engineer. To help you along with this roadmap, we’ll break down just a few of the key concepts in detail from Step 2 and look closer at DevOps.

Cloud Basics and Terms

Before jumping into more advanced cloud concepts, it’s essential to have a foundational understanding of what problems cloud computing was designed to solve, what components make up a cloud network, and the meaning of cloud terms often used in professional settings.

As a brief refresher, the cloud is a system of out-sourced data centers connected to an array of devices and users through the internet. This allows companies to have more centralized data and avoid set-up and maintenance costs.

The cloud is best understood if we divide it into the frontend (the client’s computer) and the backend (the cloud system). The backend consists of monitoring, databases, block storage, networks, computing power, queues, containers, runtime, and object storage. On the backend, there are multiple data storage systems and servers that host applications.

Data servers connect a user to their services through the internet, and a user can access, send, and modify files that are then forwarded to multiple servers. These storage resources can be accessed in multiple ways.

  • End users with a web interface that pay for the cloud per-transaction
  • A service provider dynamically issues resources on a pay-per-use basis
  • Users with a specific capacity prepared for them by the service

Cloud client companies purchase specific cloud functions like storage, cloud environments, and cloud applications, called services from cloud providers such as Amazon, Microsoft, or Google.

Groups of services called service models are used to define to what extent the client company uses the cloud: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Deployment models

In our previous article, we briefly covered deployment models by looking at private and public clouds. These are just two of the types of deployment models. Now we’ll look at hybrid clouds, multi-clouds, and community clouds.

Hybrid clouds combine the use of public and private clouds, running some modules with on-premise private clouds and others through public clouds. This allows companies to store sensitive data in private clouds while still using the benefits of public clouds for the bulk of their data.

Some companies, like LinkedIn and Facebook, get services from two or more cloud providers. This is called a Multi-Cloud environment. This is a common practice used by larger companies, as they can ensure they’re always using the provider’s strongest in the current task. These clouds can be all-public, all-private, or a mix of both.

The final deployment model, community cloud, is when a cloud is specially designed for a set of businesses that all need similar services. For example, a group of hospitals may need a cloud that supports a highly responsive, sortable, and encrypted medical record database hosted on the cloud. Community clouds ensure a level of standardization across a field of business and reduce the cost for each through a greater scale.

Cloud Computing 101: Master the Fundamentals


Auto-scaling is a cloud feature that allows a program to dynamically spin-up more application instances in response to workload intensity. Cloud engineers are responsible for setting the auto-scaling configuration that decides when new instances are spun up and the maximum number of instances allowed.

Speed vs. CPU Cost

As a single application instance handles more workload, it gets slower like other programs. Another instance of the application can be spun up to split the workload and thus maintain the speed of service. These instances cost CPU, which taxes the server hardware and has a limit of how much can be used. Cloud engineers always try to maximize speed and minimize CPU, so they’re constantly working toward the optimal balance between the two.

All configurations use scheduled auto-scaling. This is where a cloud engineer sets a maximum number of instances or CPU usage to prevent new instances from being created if reached. This helps to manage costs, as computing power is expensive, and without this ceiling, our auto-scaler could call for an unlimited number of instances, each drawing considerable computing power.

Besides setting the scheduled auto-scaling ceiling, cloud engineers also determine which type of auto-scaling is most efficient for their company’s needs, either predictive auto-scaling or dynamic auto-scaling.

Predictive auto-scaling

Predictive auto-scaling
involves using machine learning and previous data to anticipate how many instances will be required to handle the workload at any given time. This is best used if your cloud’s workload has consistent periods of peak workload, as more instances don’t have to be spun up on the fly.

The downside is, if the workload is smaller than predicted, you pay more upkeep than is needed, or if the workload is too big, you must slow the product to spin-up more instances.

For example, when designing the auto-scaling policies for Netflix, it would be good to use predictive auto-scaling if you find that the application is consistently used more on weekends than on weekdays.

Dynamic auto-scaling

Dynamic auto-scaling, on the other hand, spins up instances on the fly based on target metrics decided by the cloud engineer. Some common metrics are CPU usage, requests per minute on the program, or container resource usage. Most high level dynamic auto-scaling implementations utilize all of these metrics to ensure a sufficient number of instances.

This is best used when the cloud workload has no foreseeable pattern or remains mostly constant. The upside of this type of auto-scaling is that you’ll never have more instances than needed.

For the downside, the creation of instances on the fly can slow performance as current instances are overworked while the new one is spinning up. Also, if a key metric is missed, the program would not create a new instance when needed and run slowly as a result.

DevOps is a development strategy prevalent in cloud development teams that brings together the traditionally separate development and operations departments into a single team. The underlying goal of this strategy is to speed up application and service outputs by allowing operation feedback to come directly to the developers. This means that cloud engineers are expected to follow their application through its entire lifecycle, from conception to post-launch monitoring.

Another trend in DevOps teams is the automation of operations monitoring to streamline data collection and organization through software developed by the cloud engineers.

Therefore, in interviews, you should expect more critical thinking questions about disaster control or feedback response as well as questions on automated data management.
