Security
Kata Containers offer enhanced security by providing hardware virtualization, which creates a secure boundary around each container. This isolation helps in protecting against attacks and vulnerabilities that might affect other containers.
Performance
Kata Containers are designed to have low overhead compared to traditional virtual machines, allowing them to run with performance akin to native containers while still benefiting from hardware-based isolation.
Compatibility
Kata Containers are compatible with the OCI container runtime specification, making it possible to integrate them with existing cloud-native tools and ecosystems like Kubernetes without significant changes.
Flexibility
They offer a flexible choice for deploying containerized workloads that require the security of virtual machines, allowing organizations to meet both performance and security requirements effectively.

Although the documentation also mentions "youki", that is mentioned as a "drop-in replacement" of the default runtime basically doing the same, so let's stick with runc. The second runtime will be Kata runtime from Kata containers, since it runs small virtual machines which is good for showing how differently it uses the CPU and memory. This also adds a higher level of isolation with some downsides as well. And... - Source: dev.to / 6 months ago
Ronen: Our case study with Alibaba revealed they were using shared Linux namespaces between containers, such as their management container and our container. Sharing Linux namespaces can be dangerous. When designing a system that shares namespaces or resources between management and regular user containers, constantly carefully assess and be aware of the risks involved. Container technologies like GVisor and Kata... - Source: dev.to / 10 months ago
