New open source project ‘Kata Containers’ combines technology from Intel Clear Containers and Hyper runV and is compatible with standard container interfaces  

AUSTIN, Texas—December 5, 2017—The OpenStack Foundation today announces a new open source project, Kata Containers™, which aims to unite the security advantages of virtual machines (VMs) with the speed and manageability of container technologies. The project is designed to be hardware agnostic and compatible with the Open Container Initiative (OCI) specification, as well as the container runtime interface (CRI) for Kubernetes. Kata Containers offers the ability to run container management tools directly on bare metal without sacrificing workload isolation. When compared to running containers on virtualized infrastructure (which is the standard practice today), benefits include increased performance, faster boot time and cost efficiencies.  

Intel is contributing Intel Clear Containers technology, and Hyper is contributing runV technology to initiate the project. In addition to contributions from Intel and Hyper, the following companies are supporting the project at launch: 99cloud, AWcloud, Canonical, China Mobile, City Network, CoreOS, Dell/EMC, EasyStack, Fiberhome, Google, Huawei,, Mirantis, NetApp, Red Hat, SUSE, Tencent, Ucloud, UnitedStack and ZTE., China’s largest eCommerce platform by revenue, currently offers a container service powered by runV, the technology from that will form the basis for Kata Containers. The service exposes an easy-to-use, Docker-like workflow, so developers who know Docker are able to jump in and deploy apps immediately.  

“With virtualized containers, the basis for Kata Containers technology, we are able to provide a container service for our customers to deploy applications in a simple, fast, secure and cost-effective manner,” said Lijing Guo, general manager of JD Cloud Product Management at “Development speed is 3x to traditional IaaS, but with 50 percent cost reduction. We look forward to seeing a community form around this technology to drive it forward.”  

The Kata Containers project will initially comprise six components, including the Agent, Runtime, Proxy, Shim, Kernel and packaging of QEMU 2.9. It is designed to be architecture agnostic, run on multiple hypervisors and be compatible with the OCI specification for Docker containers and CRI for Kubernetes.  

By combining two of the most well-integrated virtualized container open source code bases and moving the project to open governance, the Kata Containers community will focus on attracting contributors, supporting diverse hardware architectures and driving technology adoption. Contributors can expect to work upstream across multiple infrastructure and container orchestration communities, including Kubernetes, Docker, OCI, CRI, CNI, QEMU, KVM, HyperV and OpenStack.  

Called Kata Containers, the new project suggests the Greek word, Καταπίστευμα (“ka-ta-PI-stev-ma”) that translates as “trust something to someone.” The word Kata in Japanese also means a detailed choreographed pattern of movements performed by individuals.  

Kata Containers at the OpenStack Foundation
Kata Containers is a container infrastructure project managed by OpenStack Foundation, the home of open infrastructure. While OpenStack users may benefit from the new technology, Kata Containers is an independent project with its own technical governance and contributor base. The Kata Containers community expects to collaborate and target all popular infrastructure providers and container orchestration frameworks in addition to OpenStack-powered clouds.  

The OpenStack Foundation provides access to a diverse, global community of 82,000+ members across 187 countries, with the ability to leverage shared administrative and scalable resources, including community management, event management, and dev/test infrastructure.

“The Kata Containers Project is an exciting addition to the OpenStack Foundation family of projects. Lighter, faster, more secure VMs technology fits perfectly into the OpenStack Foundation family and aligns well with Canonical’s data center efficiency initiatives. Like Clear Containers and previously, Kata Container users will find their hypervisor and guests well supported on Ubuntu.”
—Dustin Kirkland, vice president, Product, Canonical  

“It's China Mobile’s honor to join the Kata Containers project and project launch. It’s very well aligned with China Mobile’s Cloud Computing product. Kata Containers is a good complement for OpenStack. China Mobile has built IaaS product software stack based on OpenStack, and has a strong R&D team now, and we want to make a bigger investment in containers in the future. We think Kata Containers is a good choice for us.”
—Junwei Liu, assistant general manager of Cloud Computing Department, Suzhou R&D Center, China Mobile  

“Cloud infrastructure is rapidly evolving, and City Network is committed to offering the most innovative services to our financial services customers while also meeting industry regulations and business constraints.
