Hello everyone and welcome back to the Cognixia podcast. Every week we discuss a new topic in our episodes to help our audience learn something new and we are loving all the feedback and suggestions we are getting from you.

What is Containerization?

The simplest way we can put it is that Containerization is the building of applications using containers. 

This begs the question – What are containers?Containers are the solution to the constant challenge developers face of getting the software to run reliably when it is moved from one computing environment to another, say from the developer’s desktop to a testing environment, or from a staging environment to a production environment, or even from a physical machine in a data center to a virtual machine on the cloud. 

Containerization and virtualization are two different processes but they have some similarities. Containerization and Virtualization both enable total isolation of applications to help them be operational in multiple environments. The key differences between containerization and virtualization lie in the size and the probabilities they deal with. Virtual machines are much larger than containers, running into gigabytes, while containers are much smaller running into megabytes. 

What is Kubernetes?

Kubernetes is an open-source container orchestration platform that helps manage distributed containerized applications at large scales. It is, hands-down, the most popular tool for container orchestration in the world, usually the number one choice for most developers. 

Cognixia's Docker and Kubernetes training that covers all the important aspects of working with containers, and focuses on the two most popular tools for working with containers – Docker and Kubernetes. It is 100% online, live, and instructor-led, the sessions take place over the weekends and are delivered by highly experienced instructors.
