But if you don’t want to implement a service mesh into your infrastructure at this time, you can also use an ingress controller like NGINX to help manage traffic. Traditionally, Kubernetes has used an Ingress controller to handle the traffic that enters the cluster from the outside. Gateway describes a load balancer operating at the edge of the mesh receiving incoming or outgoing HTTP/TCP connections. Istio instead makes use of their own custom resource for managing ingress traffic. Ingress gateways allow one to define entrance points into the service mesh that all incoming traffic flows through. Modify the Istio ingress Gateway, inserting your own domains or subdomains in the hosts section. REST API calls) into a Kubernetes application normally requires a Kubernetes Ingress. It does this by implementing a sidecar approach, running alongside each service (in Kubernetes, within each pod) and intercepting and managing network communication between the services. As more developers work with microservices, service meshes have evolved to make that work easier and more effective by consolidating common management and administrative. An Istio Gateway configures a load balancer for HTTP/TCP traffic at the edge of the service mesh and enables Ingress traffic for an application.
