At the core of the modern cloud-native application movement is an open-source technology that is perhaps not as well known as it should be. That technology is the open-source etcd project, which provides a distributed key-value store that is used by all the major public cloud providers and is at the core of the Kubernetes container orchestration system.
“Etcd has become successful beyond our wildest aspirations when we started the project five years ago,”Brandon Philips, co-founder of CoreOS and currently working in the office of the CTO at Red Hat, told eWEEK. “Today every major cloud provider has etcd employed, it’s a critical part of Kubernetes and it is becoming a critical part of a lot of cloud-native projects.”
