Cloud taking over IT has become a reality - Linux cloud computing
IT is gradually migrating to the cloud. So what drives the cloud? The answer is Linux. When even Microsoft's Azure is embracing Linux, you should know that all has changed.

Accept it or not, the cloud is taking over IT has become a reality. We've seen the rise of cloud in on-premises IT over the years. So what drives the cloud? The answer is Linux.

A recent Uptime Institute survey of 1,000 IT decision makers found that around 50 percent of senior enterprise IT decision makers believe that in the future most IT work should be on the cloud or on hosted websites. Twenty-three percent of people in the survey believe this change will happen within the next year, while 70 percent believe it will happen within four years.

This is not surprising at all. Many of us are still enthusiastic about our physical servers and racks, but generally running a data center of our own doesn't yield any economic benefits.

It's simple, just compare your capital expense (CAPEX) running on your own hardware with your operating expense (OPEX) of using the cloud. But that's not to say you should outsource everything, but in most cases you should move a lot of work to the cloud.

Accordingly, if you want to get the most out of the cloud, you need to understand Linux cloud computing.

Amazon's AWS, Apache CloudStack, Rackspace, Google's GCP, and the core of OpenStack all run on Linux. So how did it turn out? As of 2014, applications deployed on Linux servers reached 79 percent of all enterprises, while those deployed on Windows servers fell to 36 percent. Since then, Linux has gained more momentum.

Even Microsoft itself understands this.

In just the past few years, Microsoft has gone from a quarter of its Azure virtual machines running on Linux to nearly a third of its Azure virtual machines running on Linux, Azure's technical director Mark Russinovich has said.

Just imagine. Microsoft, a company that is gradually turning the cloud into its main source of revenue, relies on Linux for a third of its cloud industry.

Even so far, it's hard to imagine Microsoft's transformation from a commercial software-based software company to an open-source, cloud-based service enterprise for those who like it or don't.

Linux has penetrated even deeper into these dedicated server rooms than when it first started. For example, Docker recently released its public beta on Windows 10 and Mac OS X. Does this mean that Docker will be porting its namesake container service to Windows 10 and Mac? not really.

On both platforms, Docker just runs inside a Linux virtual machine. It's HyperKit on Mac OS and Hyper-V on Windows. The GUI may look like another Mac or Windows application, but the container inside it is still running on Linux.

So, just like a lot of Android phone and Chromebook users don't even know they're running Linux. These IT users will also quietly migrate to Linux and the cloud.
