What is Kubernetes and why should you care?

What is KubernetesIf you have even a passing interest in containerization, you’ve probably heard a lot about Kubernetes.

With the focus in cloud development shifting to containers, this technology has exploded in popularity. But what is Kubernetes and why does it matter to your business?

The problem

Businesses and their customers are pushing for flexibility, faster time to market and software that runs seamlessly across different environments.

The obstacle many enterprises face, however, is that different software environments have different restrictions and complexities. For example, if your development team wrote the software with one operating system in mind, you might have trouble running it on a different operating system. This can also be true for the underlying hardware or cloud environment.

This creates conflict between different parts of your organization. The development team may write a piece of software that causes difficulties for operations, for example. It can also mean performance issues when you deploy your applications in new environments. Even small differences can cause large problems.

Containers: The solution to the problem

One solution to this problem is something called a container.

A container is a packaged piece of software that includes everything required to run it: all of the code and all of its dependencies. This separates the software from its underlying infrastructure. Even the operating system is virtualized. No matter where you run a containerized application, it will function the same way.

Kubernetes: The solution to the solution

All of this might sound like a perfect solution, but using containers also creates an issue of its own. How can you manage and deploy all of your containerized applications? Large enterprise systems could include a huge number of containers.

That’s where Kubernetes comes in. Kubernetes is an open source solution for managing, automating and deploying containerized applications.

Here’s what that could mean for your business:

  • Cost savings. Kubernetes clusters are known for being low maintenance. Your team won’t have to write its own container automation scripts. Team members also won’t have to choose between reinventing the wheel or passing up the advantages of a shared infrastructure. You might also be able to reduce hardware costs by making more effective use of your current hardware.
  • Faster time to market. Kubernetes is perfect for DevOps. Good container management means that so long as the software runs, the deployment will almost always be painless. This means quicker deployment.
  • IT flexibility. In the modern enterprise, software runs on any number of private and shared infrastructures. Having a container management solution means you won’t have to sacrifice performance or make major adjustments to move your applications. You can run software wherever your business needs it. That makes your team more nimble.

If you’re interested in using a Kubernetes solution for your business, start by knowing how an open approach for managing applications across different cloud environments can help.
