Pod Networking --> OpenShift uses a software-defined networking (SDN) approach to provide a unified cluster network where every Pod gets its IP address. This enables communication between pods across different nodes without NAT.
Network Policies --> Administrators and developers can use network policies to control the flow of traffic at the pod level within an OpenShift cluster.
Services --> Services in OpenShift act as an abstraction layer, providing stable IP addresses and DNS names to manage access to the set of pods that make up an application.
Ingress and Routes --> OpenShift has built-in support for managing external access to services in the cluster through routes and Ingress controllers, allowing users to reach services from outside the cluster.
Egress IP and Egress Network Policies --> These features allow the control of outbound traffic from pods and the assignment of additional IP addresses to nodes for this traffic.
Multitenancy --> OpenShift provides network isolation by dividing the cluster into multiple virtual networks for different tenants or groups.
Service Mesh --> OpenShift includes a service mesh layer for managing microservices-based applications, providing capabilities like traffic management, security, and observability.
Network Plug-ins --> OpenShift supports different CNI (Container Network Interface) plug-ins for various networking use cases, like OpenShift SDN, OVN-Kubernetes, etc.
