Definition

Kata Containers is an open-source project that provides lightweight virtual machines (VMs) to run container workloads. It combines the speed and flexibility of containers with the security advantages of VMs, offering an additional layer of isolation between containerized applications. Kata Containers are compatible with the Open Container Initiative (OCI) and Kubernetes, making them suitable for environments requiring enhanced security without sacrificing performance.
