What Is Containerization? A Definition

Want to make your application infrastructure more agile, automated, and resilient? A cloud native architecture based on containers and containerization, plus orchestration tools like Kubernetes, allows you to scale up and down easily, whether in the cloud or on premises. These technologies empower your development teams to release updates more frequently and efficiently, ultimately leading to more innovation and less operational overhead. Let’s look at one enabling technology.

What Is Containerization?

Containerization is a method of encapsulating an application and its runtime environment—including libraries, dependencies, and configuration files—into a self-contained unit called a container.

The purpose of containerization is to make applications portable, consistent, and, in many instances, easier to scale up by adding more containers. Docker is a popular platform for creating containerized applications, which are often then managed using Kubernetes.
