Kubernetes Cluster

Kubernetes Engine is a managed, production-ready environment for deploying containerized applications. It brings our latest innovations in developer productivity, resource efficiency, automated operations, and open source flexibility to accelerate your time to market.

Launched in 2015, Kubernetes Engine builds on Google's experience of running services like Gmail and YouTube in containers for over 12 years. Kubernetes Engine allows you to get up and running with Kubernetes in no time, by completely eliminating the need to install, manage, and operate your own Kubernetes clusters.
