Here's a simple explanation

Kata Containers

Traditional Virtual Machines are secure but not as fast as Containers. Kata Containers Project is like a Virtual Machine as lightweight as a Container. In other words, Kata Containers solved the low speed problem of VMs.

gVisor

Containers running inside a sandbox named gVisor (there's a sandbox per container)
