The Path to Cloud Native
Google spent over ten years developing, applying and refining the principles of cloud native computing. A cloud-native application is:
- Container-packaged. Applications are composed of hermetically sealed, reusable units across diverse environments;
- Dynamically scheduled, for increased infrastructure efficiency and decreased operational overhead; and
- Microservices-based. Loosely coupled components significantly increase the overall agility, resilience and maintainability of applications.
These principles have enabled us to build the largest, most efficient, most powerful cloud infrastructure in the world, which anyone can access via Google Cloud Platform. They are the same principles responsible for the recent surge in popularity of Linux containers. Two years ago, we open-sourced Kubernetes to spur adoption of containers and scalable, microservices-based applications, and the recently released Kubernetes version 1.3 introduces a number of features to bridge enterprise and cloud native workloads. We expect that adoption of cloud-native principles will drive the same benefits within the OpenStack community, as well as smoothing the path between OpenStack and the public cloud providers that embrace them.
Making OpenStack better
We hear from enterprise customers that they want to move towards cloud-native infrastructure and application patterns. Thus, it is hardly surprising that OpenStack would also move in this direction , with large OpenStack users such as eBay and GoDaddy adopting Kubernetes as key components of their stack. Kubernetes and cloud-native patterns will improve OpenStack lifecycle management by enabling rolling updates, versioning, and canary deployments of new components and features. In addition, OpenStack users will benefit from self-healing infrastructure, making OpenStack easier to manage and more resilient to the failure of core services and individual compute nodes. Finally, OpenStack users will realize the developer and resource efficiencies that come with a container-based infrastructure.
OpenStack is a great tool for Kubernetes users
Conversely, incorporating Kubernetes into OpenStack will give Kubernetes users access to a robust framework for deploying and managing applications built on virtual machines. As users move to the cloud-native model, they will be faced with the challenge of managing hybrid application architectures that contain some mix of virtual machines and Linux containers. The combination of Kubernetes and OpenStack means that they can do so on the same platform using a common set of tools.
We are excited by the ever increasing momentum of the cloud-native movement as embodied by Kubernetes and related projects, and look forward to working with Mirantis, its partner Intel, and others within the OpenStack community to brings the benefits of cloud-native to their applications and infrastructure.
