What are the differences between Ingress and Load Balancer in Kubernetes?

Question

Accepted Answer

Ingress is a layer 7 HTTP routing mechanism while Load Balancer is a layer 4 TCP/UDP load balancer in Kubernetes.

Ingress is used to expose HTTP and HTTPS routes to services inside the cluster, while Load Balancer is used to distribute traffic across multiple nodes.
Ingress provides features like SSL termination, path-based routing, and name-based virtual hosting, while Load Balancer focuses on distributing traffic based on IP and port.
Ingress is a resource that manages external access to services in a cluster, while Load Balancer is a service that exposes services to the external network.
Ingress controllers like Nginx, Traefik, or HAProxy are used to implement Ingress rules, while Load Balancer services are typically provided by cloud providers like AWS ELB or GCP Load Balancer.
