Unlike NodePort or LoadBalancer, Ingress is not actually a type of service. Instead, it is an entry point that sits in front of multiple services in the cluster. It can be defined as a collection of routing rules that govern how external users access services running inside a Kubernetes cluster.
Hereof, does ingress have load balancer?
Ingress is a Kubernetes resource that encapsulates a collection of rules and configuration for routing external HTTP(S) traffic to internal services. On GKE, Ingress is implemented using Cloud Load Balancing.

Similarly one may ask, how do I choose API Gateway vs ingress controller vs service mesh?
So how do you decide which tool is right for you? We’ll make it simple: if you need API gateway functionality inside Kubernetes, it’s usually best to choose a tool that can be configured using native Kubernetes config tooling such as YAML. Typically, that’s an Ingress controller or service mesh.
Is ingress controller a load balancer?
An Ingress Controller is: A service of type Load Balancer backed by a deployment of pods running in your cluster. (Ingress Objects can be thought of as declarative configuration snippits of a Layer 7 Load Balancer.)
Is ingress same as API Gateway?
The ingress controller service is set to load balancer so it is accessible from public internet. An api gateway is used for application routing, rate limiting, security, request and response handling and other application related tasks.
Is Istio a service mesh?
Istio is a service mesh—a modernized service networking layer that provides a transparent and language-independent way to flexibly and easily automate application network functions.
Is Kubernetes a service mesh?
A Kubernetes service mesh is a tool that inserts security, observability, and reliability features to applications at the platform layer instead of the application layer. Service mesh technology predates Kubernetes.
Is Kubernetes ingress an API Gateway?
Gloo is a Kubernetes Ingress that is also an API gateway. It is capable of providing rate limiting, circuit breaking, retries, caching, external authentication and authorisation, transformation, service-mesh integration and security.
What is the difference between ingress and service Kubernetes?
While the Kubernetes Ingress also handles external access to the services, it is not a Service, like the other options, but rather an API object. This works differently than Services in that it creates an Ingress resource that routes traffic based on a set of rules.
Why do we need service mesh in Kubernetes?
Why do I need a service mesh? If you are building applications on Kubernetes, then a service mesh like Linkerd provides critical observability, reliability, and security features with one big advantage: the application doesn’t need to implement these features, or even to be aware that the service mesh is there!
Why do we need service mesh?
A service mesh is a software infrastructure layer for controlling and monitoring internal, service-to-service traffic in microservices applications. Service mesh provides some of the middleware and some of the components that enable service-to-service communication, such as dynamic discovery.
