CONTAINER DISCOVERYVIA REGISTRY
ORCHESTRATION WITHKUBERNETES
Red Hat works with the open source community to drive standards for containerization.
ISOLATION WITH LINUX CONTAINERS
CONTAINER FORMAT WITH DOCKER
Atomic Host - a container-optimized, minimal footprint OS powered by Red Hat Enterprise Linux
Telemetry - logging and metrics for pods/containers, services and underlying infrastructure to make informed decisions
Runtime and Packaging Format - standardized container packaging format and runtime, powered by Docker (and OCI)
Automation and host configuration management via Cockpit to dynamically provision and configure container host clusters
Orchestration - for complex multi-container services, powered by Kubernetes
Networking - scalable, multi-host container networking, powered by Open vSwitch, that runs anywhere Red Hat Enterprise Linux runs
Cluster Services - Scheduling for services across a container host cluster, powered by Kubernetes
Storage, with persistent storage plugins to enable running of stateful services in containers
Atomic Registry - integrated storage and management for sharing container images
Security to prevent tenants from compromising other occupants
