Kubernetes Ingress is a vital component for managing external access to services within a Kubernetes cluster, acting as a centralized entry point that routes incoming HTTP and HTTPS traffic based on predefined rules such as host or path. It simplifies traffic management by eliminating the need for individual load balancers or public IP addresses for each service, offering features like load balancing, SSL/TLS termination, and name-based virtual hosting. While it shares some similarities with traditional load balancers, Ingress is specifically tailored for Kubernetes environments, enabling advanced routing and traffic management for containerized applications. The Ingress Controller processes the routing rules defined in the Ingress resource, ensuring that traffic is directed appropriately within the cluster. The Kubernetes Gateway API is emerging as a more feature-rich and standardized approach to network management, addressing some of Ingress's limitations by supporting additional protocols and advanced traffic management features. While Ingress and egress manage incoming and outgoing traffic, respectively, they are both crucial for maintaining efficient communication in a Kubernetes environment.
