Kata Containers Overview

In this blog, we will share an overview of Kata containers Overview and its functionalities.

 

WHAT IS MEAN BY KATA CONTAINERS?

  • Kata containers is an open source project which provides lightweight virtual machines that will perform like containers.
  • In other words, It provides the container agility in VMs.
  • Unlike VMs, containers are smaller and faster which scale up in a matter of seconds.
  • When comes to security, containers are not considered as a secure as VMs.
  • VM applications are running in an isolated mode whereas containers are running in a shared mode which leads to security and privacy concerns.
  • Kata Containers are trying to overcome the security and performance issues.

 

KATA HIGH-LEVEL ARCHITECTURE

 

Kata Containers Overview

 

  • As the current container model, It has shared the kernel with the isolated namespace.
  • But whereas in kata containers, each container is hypervisor isolated which like secure VM.
  • It improves the security and performance of the container.
  • This Kata containers model will provide dedicated namespace for each tenant in an isolated environment.

 

KATA ECOSYSTEM

  • Kata container projects are combination of two existing open source projects named Intel Clear containers and Hyper runV.
  • These two technologies will help KATA to provide speed and security.
  • Intel Clear containers are focusing on the performance and enhanced security. They are planning to boot the KATA containers less than 100ms.
  • Hyper runV will take care of CPU architectures and hypervisor types.
  • This will eliminate the difference between containers and VM’s.
