Why Red Hat Quay?
Container registries are the backbone of any modern container platform. Container runtimes and orchestration systems do not have long-term storage and image distribution capabilities. Container platforms rely on a registry as a critical part of the initial deployment before a container can run. Beyond the initial deployment, the life cycle of running containerized workloads on modern platforms requires a reliable and highly fault-tolerant registry.
Many events in an OpenShift cluster, or other Kubernetes environment, involve the registry. For example, rolling out configuration changes, reacting to scaling events, handling node maintenance or downtime, or rolling out updates all require interaction with the registry. Even minutes of downtime of a registry can disrupt developers and production applications.
In a multicluster environment spanning multiple sites and cloud services, a resilient central registry is even more important. Red Hat Quay provides a purpose-built, central, scalable registry platform with a proven track record using the same code base as the public Quay.io service that delivers millions of images daily.
