Istio Rate Limiting Simplified | Envoy Filter CRD | Rate Limiting | Demo | IMESH

Explore Istio rate limiting and see a tutorial on how to set up Istio rate limiting per IP at Ingress.

Services in Kubernetes can become overwhelmed with requests because of multiple reasons. It can be due to a spike in legitimate traffic, DDoS, application misconfiguration, and so on. If not checked in time, it can lead to cascading failures and cause a bad user experience.

Rate limiting is a mechanism to prevent such scenarios from happening and to protect K8s services from being overwhelmed with requests. Istio service mesh can help DevOps and architects implement rate limiting for services in the mesh, using Envoy filter CRD.

In the video, we’ll go through Envoy filter CRD in detail and explore the types of Istio rate limiting: global and local. You’ll see when to use Istio local or global rate limiting. Finally, we’ll see a demo on how to set up rate limiting per client IP at the Ingress using Istio global rate limiting.
