Global Distributed Consensus: The Missing Piece in Kubernetes
Kubernetes runs on etcd, which uses the Raft consensus algorithm. It's a proven model for what it was designed to do: keep a single cluster's state perfectly consistent. When you create a deployment or a pod dies, every node in the cluster agrees on the new state of the world almost instantly.

Implementing Resource Versioning in Conveyor CI
So we have to then take into consideration our data store and investigate if it's able to handle this form of incrementation. Conveyor CI uses etcd, a key-value store, it is reliable and highly performant. As we investigated further into the architecture of etcd, we realized that internally etcd uses Multi-Version Concurrency Control (MVCC) which allows reads at specific revisions of a record or key. This means for every update to an etcd key you make, etcd stores the previous version of that record and you can query or read it later on. So technically, rather than having to create a new record each time we update a resource, we can rely on etcd’s internal MVCC to store revisions. Another upside to this is that etcd also uses the incremental revision numbering format so we can also rely on that.

A Complete Guide to etcd: The Distributed Key-Value Store Powering Cloud Infrastructure
etcd is a distributed key-value store designed for reliability, high availability, and consistency. It is a Cloud Native project that powers much of the tools utilized in the Cloud Ecosystem today. It is used projects like Kubernetes, CoreOS, OpenShift, Cloud Foundry any many more. It is primarily used to store configuration, state and metadata in Cloud Systems. This article will take you through a complete guide to understanding etcd to the point of being able to integrate it into your project. We shall cover how to install it, setup a cluster, store and query etcd, operating and managing etcd and many more concepts. By the end of this blog article, you will have a solid understanding of etcd.
