Kata Containers is a merge of 2 hypervisor based container runtime efforts: Hyper’s runV and Intel’s Clear Containers. With Kata Containers, each container is hypervisor isolated just like an EC2 or GCE instance. It is an OCI compatible runtime and as such can seamlessly work with containerd or hyperd. Moreover it fully supports the Kubernetes CRI APIs and thus can run and manage hypervisor isolated Kubernetes pods through CRI-O, containerd-cri or frakti. Finally, Kata Containers is a multi architecture project as it supports x86, ARM, Power and s390x platforms.During this talk we will describe the Kata Containers architecture and how it drastically reduces the virtualization overhead in order to be as fast as a namepace based container runtime while being as secure as a legacy VM. We will also run a multi tenant Kubernetes demo in order to show how Kata Containers could become the cornerstone of a secure, infrastructure free, container cloud.
