If Your Business Isn’t Already Using Docker, You’re Missing Out On a Lot: Here’s Why

If Your Business Isn’t Already Using Docker, You’re Missing Out On a Lot: Here’s Why

If you haven’t already heard of things like Docker and Containerization, then chances are that your business might not be running as efficiently as it could. These two concepts are two of the hottest developments in the realm of Computer Science and only rightly so.

The fact of the matter is that containerization is a prime example of what disruptive technology is and well, like every disruptive technology, it has a true potential to replace whatever we currently have that’s is equivalent.

It can be likened to how the car has permanently replaced the horse-drawn carriage as our land transportation of choice. And that is not an exaggeration.

The Virtual Machine, Explained

So, what’s all this hype about? Well, we need to know what exactly is the current technology that containerization might replace, and that technology is none other than the virtual machine.

A virtual machine is defined as “an operating system that is installed on software that imitates the way dedicated hardware would function.”

So, in essence, an end user would have the same experience as one would with dedicated hardware.

The virtual machine was developed in order to address the concern that computers were being under-utilized. Back then, the computer-savvy people were worried that running multiple servers and processes on a single computer would result in a virtual tug of war for computer resources between the two processes, which will ultimately result in having one or both of these processes crash.

And this proved to be a costly limitation for computers. To put things into the correct perspective, assume a single server would cost $8k to run and maintain, and that you need 3 servers for your system.

Sure, you could shell out the $24k straight up and get your system online, but there’s a big chance that your computers may only be running at 30% of their true capacity. That, and think of the electricity bills that come with powering 3 computers!

With a virtual machine, you are then able to make full use of your computer’s potential. So, instead of running your system on three computers, each running at 30% capacity, and costing you a total of $24k for maintenance and operation, you can do the same thing on a single computer running at 90% capacity and costing only $8k.

Who doesn’t want to save $16k after all?

Docker and Containerization, Explained

Containerization runs on the same concept as the virtual machine, but it takes that concept to an entirely different level. So, if virtual machines are meant to emulate dedicated hardware, containers are able to do the same on a single virtual machine (or instance) rather than having to create a new instance for each process.

So, you can essentially run several container images on a single instance of Windows.

Now, Docker is the most popular container program and it allows developers to run any application as a lightweight, self-sustaining package. It essentially allows you to make more efficient use of your hardware, especially in this age where computers are more powerful than they have ever been.

But, like all tools, you need to be able to learn how to use Docker properly. Pro Docker Training provides some of the most comprehensive training programs on the market. Besides, if you don’t adopt Docker soon, your competition will.
