Full-stack automated operations

Red Hat OpenShift 4 offers automated installation, upgrades, and life cycle management for every part of your container stack.

  • Single-step installation for Kubernetes applications
  • Centralized administrative control for over-the-air updates and performance tuning with Kubernetes operators
  • Continuous security through built-in authentication and authorization, secrets management, auditing, logging, and integrated container registry

Support for developer productivity

Code in production mode for any infrastructure. Red Hat OpenShift 4 supports well-known developer tools and helps streamline your build and delivery workflows.

  • Develop and test with a minimal, preconfigured OpenShift cluster on your laptop with Red Hat CodeReady Containers
  • Support for your choice of languages, databases, frameworks, and tooling
  • Streamlined workflows like automated container builds, built-in CI/CD, and application deployments

Built-in service mesh for microservices

Microservices architectures can cause communication between services to become complicated to encode and manage. The OpenShift service mesh abstracts the logic of interservice communication into a dedicated infrastructure layer, so communication is more efficient and distributed applications are more resilient.

  • Installed and updated via Kubernetes operators
  • Incorporates Istio service mesh, Jaeger (for tracing), and Kiali (for visibility) on a security-focused, enterprise platform
  • Frees developers from being responsible for service-to-service communication

A unified Kubernetes experience on any infrastructure

Red Hat OpenShift 4 is a consistent, managed Kubernetes experience for on-premises and cloud-based deployments.

With unified ops and admin controls, workloads are decoupled from infrastructure, meaning less time spent on system maintenance, more time coding critical services.
