The “cloud.” What was once a trendy, science fiction–sounding buzzword has become an inescapable part of our everyday personal and professional lives. Even though we understand what the cloud does, the way it works and how it is evolving is a far more complex subject. This list of cloud computing statistics will give you an idea of just how significant it really is.
- The “cloud” is a vital online technology that is used all over the world.
- Since the COVID-19 crisis, the cloud computing market has been on a rapid upward trajectory when it comes to cloud adoption, infrastructure, spending and development.
- We’ve put together a list of 26 of the most interesting, relevant and revealing cloud computing statistics that demonstrate how big the cloud is and how it’s predicted to evolve.
Of course, it is impossible to predict with 100 percent accuracy how the future of cloud computing will look — COVID-19 showed us that everything can change — but certain patterns concerning cloud technologies and cloud infrastructure have emerged and they warrant analysis. Even if we disregard these, current cloud computing stats speak volumes about the state of cloud computing and where it’s headed.
The three major types of cloud computing are: Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). If you are interested in learning more about these terms, we invite you to read our cloud terminologies article, which explains how they function in greater detail.
It’s huge. In 2020, the global cloud computing market was valued at $371.4 billion, and it is estimated that by 2025 it will rise to a staggering $832.1 billion. 
With 94 percent  of all enterprises using cloud services in some form or another, it’s safe to say that cloud computing is here to stay and will only get even bigger in the future.
Simple Cloud Computing Facts You Need to Know
What we refer to as “the cloud” actually exists as a physical network of servers. These servers host data that you can access via an internet connection. That’s the basis of all cloud software, and one could argue that’s how the internet works as a whole. Since all you need is an internet connection, cloud computing is super convenient for both business and personal use.
Simply put, cloud computing is all about using the internet to connect to online services hosted on the cloud. These services include everything from simple cloud storage to cloud infrastructure platforms, like AWS. Plus, all of your favorite online streaming content is hosted on cloud servers, whether it’s a Netflix series, your Spotify playlist or a YouTube channel.
While cloud computing is an integral part of every modern organization (typically taking up a large portion of IT infrastructure spending), personal users also depend on cloud services. For example, if your default email client is Gmail, or if you’ve ever shared a file through Dropbox, you’re already using the cloud, even if you’re unaware of it.
Public Cloud vs Private Cloud vs Hybrid Cloud
There are three main types of cloud computing deployments: public cloud, private cloud and hybrid cloud.
Public clouds are owned and operated by third-party service providers and are the most common. This includes cloud storage providers like Sync.com and pCloud, as well as large platforms like Microsoft Azure. The advantages of using a public cloud include lower costs, no need for maintenance, high reliability and almost unlimited scalability.28
Private clouds are used by just one organization. Consequently, the cloud infrastructure of a private cloud (the physical servers that host the private cloud) is maintained by that organization. These are often used by government agencies and large organizations. Their advantages are better control and privacy, as well as increased flexibility.28
Hybrid clouds combine the advantages of public and private clouds. With a hybrid cloud solution, you can, for example, only use public cloud resources when you really need them, saving you a lot of money in the meantime.
Are Personal Cloud Computers the Future?
What was once considered science fiction could soon become reality. Microsoft has already started rolling out its Windows 365 service, which offers virtual personal computers running Windows 10 or 11.
The service gives you access to a Windows cloud computer that works exactly like a physical one does. The virtual computer can be streamed to any device you choose, which promises to bring a revolution in cloud computing, if everything works as planned.
