Container Journal “etcd data store project key to scaling Kubernetes clusters”

The etcd distributed key/value store is starting to play a key role in the management of fleets of Kubernetes clusters in the enterprise.

Currently an incubation-level project being advanced under the auspices of the Cloud Native Computing Foundation (CNCF), the open source etcd project was originally launched by IBM. Since it became a CNCF, the etcd data store is being more widely employed to provide a single, consistent source of truth about the status of a Kubernetes environment, including all clusters and pods and the application instances within them at any given point in time. The Kubernetes application programming interface (API) server stores each cluster’s state data in etcd, which Kubernetes clusters employ to reconfigure themselves when changes occur.
