ISTIO Gateway

Istio Gateway is another configuration model offered by ISTIO along with the capabilities that provide support for Kubernetes Ingress. An ISTIO gateway is a concept that provides more extensive customization and flexibility than Ingress and allows ISTIO features such as monitoring and routing rules to be applied to the traffic flowing into the Kubernetes cluster.

Purpose of an ISTIO Gateway

The main purpose served by an ISTIO Gateway is to act as a network-ingress point and to guard and control access to the cluster of the traffic that originates outside of the cluster. Moreover, Istio's Gateway also takes care of load balancing and virtual-host routing.
