What is OpenShift master?
Similarly, it is asked, what is ETCD in OpenShift?
An etcd server: OpenShift uses etcd to store system configuration and state. Controllers: Controllers are the components that run with the masters that makes sure the running system matches the desired state as stored in etcd. For example a DeploymentController watches for new Deployment objects and processes them.
Thereof, why should I use OpenShift?
OpenShift enables efficient container orchestration, allowing rapid container provisioning, deploying, scaling, and management. Cutting down on time that would otherwise be spent managing containers improves your company's productivity and speeds up application development.
Etcd is used successfully in production environments by large cloud providers such as AWS, Google Cloud Platform, and Azure. Etcd's job within Kubernetes is to safely store critical data for distributed systems. It's best known as Kubernetes' primary datastore used to store its configuration data, state, and metadata.
