Kubernetes is an open-source platform for automating deployment, scaling, and operations of application containers across clusters of hosts, providing container-centric infrastructure.

With Kubernetes, you are able to quickly and efficiently respond to customer demand:

  • Deploy your applications quickly and predictably.
  • Scale your applications on the fly.
  • Seamlessly roll out new features.
  • Optimize use of your hardware by using only the resources you need.

Our goal is to foster an ecosystem of components and tools that relieve the burden of running applications in public and private clouds.

Kubernetes is:

  • portable: public, private, hybrid, multi-cloud
  • extensible: modular, pluggable, hookable, composable
  • self-healing: auto-placement, auto-restart, auto-replication, auto-scaling


A number of PaaS systems run on Kubernetes, such as Openshift, Deis, and Eldarion. You could also roll your own custom PaaS, integrate with a CI system of your choice, or get along just fine with just Kubernetes: bring your container images and deploy them on Kubernetes.

Since Kubernetes operates at the application level rather than at just the hardware level, it provides some generally applicable features common to PaaS offerings, such as deployment, scaling, load balancing, logging, monitoring, etc. However, Kubernetes is not monolithic, and these default solutions are optional and pluggable.

Additionally, Kubernetes is not a mere “orchestration system”; it eliminates the need for orchestration. The technical definition of “orchestration” is execution of a defined workflow: do A, then B, then C. In contrast, Kubernetes is comprised of a set of independent, composable control processes that continuously drive current state towards the provided desired state. It shouldn’t matter how you get from A to C: make it so. Centralized control is also not required; the approach is more akin to “choreography”. This results in a system that is easier to use and more powerful, robust, resilient, and extensible.

What does Kubernetes mean? K8s?

The name Kubernetes originates from Greek, meaning “helmsman” or “pilot”, and is the root of “governor” and “cybernetic”. K8s is an abbreviation derived by replacing the 8 letters “ubernete” with 8.


The Kubernetes project was started by Google in 2014. Kubernetes builds upon a decade and a half of experience that Google has with running production workloads at scale, combined with best-of-breed ideas and practices from the community
