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

• 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.
