While the concept of virtualization is as old as the internet itself, cloud computing as a service only took off in the early 2000s with the launch of Amazon’s cloud computing infrastructure followed by Amazon Web Services (AWS). Over the past 20 years, more and more companies have committed to migrating their infrastructure, platforms and software to cloud services.
While that migration was well underway prior to the COVID-19 pandemic, the paradigm-shift brought about by the subsequent lockdown has only served to accelerate it. A 2021 O’Reilly survey on cloud adoption found that 90% of respondents used cloud computing, an increase over the previous year’s 88%. Moreover, almost half (47%) reported that they were pursuing a “cloud first” strategy, rather than utilizing it as a backup.
With cloud computing fast becoming the default IT operation, if you’re interested in working with technology, then cloud computing is going to affect you, one way or another. So, let’s take a look at the essentials of cloud computing, some of the best cloud computing online courses for learning the basics and how you can build up your cloud computing bonafides.
Why Is Cloud Computing Knowledge an Essential Skill?
Cloud computing continues to gain traction as the preferred means of IT services. Gartner predicts that spending on public cloud computing services will grow 20.7% from $490 billion in 2022 to $591.8 billion in 2023. That report on cloud services shows that AWS is still the market leader, with a 38.9% share of worldwide revenue in 2021. However, competitors are continuing to catch up, with Microsoft Azure gaining a 21.1% share, followed by Alibaba at 9.5% and Google Cloud at 7.1%.
This steady level of growth is for all areas of cloud services, including:
- Infrastructure as a service (IaaS) — This cloud service provides access to IT infrastructure, such as servers and virtual machines (VMs), as well as data storage and operating systems. Gartner forecasts a 26% growth rate for IaaS from 2022 to 2023.
- Platform as a Service (PaaS) — A cloud service that offers an on-demand environment that can be utilized for developing, testing and delivering software applications. There is a predicted 23% growth for PaaS in 2023.
- Software as a service (SaaS) — Perhaps the most common and well-known form of cloud services, these are licenses for software applications, which include regular updates, upgrades, security patching and other ongoing maintenance. Being a more established service, there’s a projected growth of 17% for SaaS in 2023.
The reason for this continued growth? Whether it’s entirely located off-site, or as a hybrid system that’s partially onsite, cloud systems provide several benefits over older, entirely “on-premises” system that organization of all sizes can benefit from:
- Reduced costs: Hosting your own on-premise hardware requires the purchase and maintenance of servers, networks and storage. That’s in addition to developing, installing and updating the required operating system and other software. Although cloud services are licensed and come with a subscription fee, all-in-all it often amounts to lower rates than what it costs to support traditional on-premise hosting.
- Greater scalability: Arguably the greatest asset of cloud systems is their scalability. Expanding or adding on to an older, on-premise system would require purchasing new hardware, replacing and upgrading technology and finding the physical space to store it all. Expansion through cloud services can happen rapidly, with little-to-no downtime or interruption in service to the end-user.
- More flexibility and better utilization: With a cloud subscription, an organization only has to pay for the amount of space and services that it needs. There’s no risk of having unused space and idle services using up CPU power or memory, or wasting electricity. There’s also no hassle of having to operate during prescribed hours of operation, as a cloud service can be accessed when and where it’s needed best.
- Increased productivity: Managingon-site data centers and updating proprietary software requires an internal IT team to manage operations such as hardware setup and software patching. These chores can eat up valuable time, whereas shifting those responsibilities to a cloud service provider can allow an IT team to focus on larger, more important business goals.
- Improved security: Even on-premise systems are subject to security breaches, and updating software to remove vulnerabilities requires constant testing and patching. Cloud providers constantly monitor their services to discover and immediately react to any breaches or data loss. They also frequently update software and security measures as part of their efforts to protect data, infrastructure and users.
Top 5 Online Cloud Computing Courses for Beginners
Whether you’re hoping for a better understanding of how cloud computing works from a business perspective, you’re looking to get into writing code for cloud platforms, or you’re exploring ways that your enterprise can leverage cloud services, it’s a critical advantage to at least familiarize yourself with cloud computing.

Course length — Single 1.7 hour course.
Cost — Available via free trial or $29 a month subscription.
At just over an hour, this single course provides a helpful overview of cloud platforms, covering the major ones such as Amazon Web Services and Microsoft Azure in addition to private clouds. This is very much a non-technical course for those who need to learn the fundamentals of cloud computing.
If you’re interested in a surface-level introduction to cloud computing, this is a quick and inexpensive way to start.
Course length — 23 hours over four weeks.
Cost — Students can audit for free, but earning a certification requires a Coursera subscription.
The first of a six-part Cloud Computing Specialization, this course goes a little deeper in teaching fundamental cloud computing concepts such as distributed algorithms and design concepts. While it’s considered a beginner-level course, there are some programming assignments that require experience with the C++ programming language. It is a self-paced course that includes quizzes and graded assignments with peer feedback.
Consider this course if you’re familiar with the basics of cloud computing but want to dig deeper into how the systems work while trying your hand at programming.
Course length — 13 hours over four weeks.
