Containerization Basics: The Most Compelling Reason You Might Want To Use It For Your Programming Needs

The tech industry is an environment that is ever-changing and almost unpredictable. You never know when a new breakthrough might surface and you never know when a new use for current tech can be found. The thirst for knowledge and the drive to innovate have always been our defining traits as human beings, after all.


The realm of programming is one that is particularly in demand. There will always be an urgent need for more efficient and more powerful hardware, and more streamlined and more resource-efficient software. The ability to process and share big files is one that is highly valued. 

Containerization is part of the latter and it is one of the most anticipated forms of virtualization that we currently have at our disposal. It has so many advantages over the use of virtual machines that we might as well discard virtual machines altogether in favor of containerization. The only problem is that not many people are well-versed in the subject of containerization. And this causes people to miss out on the significant benefits of this new tech. 

This article is intended to give readers a basic understanding of what containerization is and how it can be of use to them in the programming field. So, first things first:

What Is Containerization?

Containerization is a lightweight alternative to the use of virtual machines. It works by containing an application or program within its own operating environment. This environment includes all the resources necessary to allow the program or application to work independently, and it allows it to run on any suitable machine without taxing its resources.

What Are The Benefits Of Containerization?

  • High Scalability – Because you’re only working with components, companies are able to scale just the functions that they want to adjust without impacting the entire application. You can think of this as a modular program where you only touch the parts that you want to make adjustments to without affecting other components.
  • Rapid Deployment – Because containers are packed with all the resources they need to run, you can run these programs in any suitable environment without the need for a virtual machine. The deployment of a container often lasts just a few seconds. So, you can essentially run as many programs as you need in order to meet demands. 
  • Process Isolation – process isolation greatly improves security because of the fact that an application’s major resources are placed in a separate container. This reduces the risk for dependencies and security breaches.
  • More Accurate Testing – because changes are easily tracked and because containers run on their own, there are almost no extraneous variables that could complicate testing. All tests are essentially carried out in an environment that’s as controlled as it possibly can be,  allowing software developers to thoroughly test an app before adding final touches.

There’s a very good reason why major players in the IT industry are investing heavily on containerization. And while this is merely the tip of the iceberg, there are plenty of resources, like this programming podcast, that could give you a deeper understanding of containerization and other related topics.

Technology is nothing less than an arms race. Those who are able to get earlier access to the latest technologies are able to develop their systems for it in order to maximize the benefits that newer technologies yield. Containerization is one of those technologies and while you may not completely understand it right now, being able to utilize it could grant you an edge over your competitors. A great example of this is how Apple is able to leverage many iPad features over its Android counterparts.
