It is configured with a protocol and a port for front-end (client to load balancer) connections, and a protocol and a port for back-end (load balancer to back-end instance) connections. The following diagram is from the original ALB ingress controller announcement to show benefits such as ingress path-based routing and the ability to route directly to pods in Kubernetes instead of relying on internal service IPs and kube-proxy. Storage resource. HTTP load balancing is often dubbed the most flexible type of load balancing because it allows you to form distribution decisions based on any information that comes with an HTTP address. Far more sophisticated and complex configurations are common.| Figure 5: OCI public load balancer architecture. Deploying multiple servers also eliminates a single point of failure, making the website more reliable. The reason load balancers must be more sophisticated to handle application information is that the data itself is more complex. However, this can be the source of problems in a scenario where all nodes in the load balancing pool are redlining and we insert a new node into the pool (as you’d see in a scale-up event).
