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. ▬▬▬▬▬ Timestamp ▬▬▬▬▬▬ 00:35 Agenda 01:15 Rate Limiting: Introduction 03:40 Istio rate limiting using EnvoyFilter CRD 04:59 Example of an EnvoyFilter 09:54 Descriptors and Actions 13:22 Local Rate Limiting 14:57 Global Rate Limiting 16:17 Local vs Global Rate Limiting 18:05 Demo 20:35 Demo: Global Rate Limiting config 23:45 Demo: Global Rate Limiting EnvoyFilter 26:15 Demo: Global Rate Limiting in action 28:33 Demo: Istio IngressGateway client IP address Access the code used for the video here: https://github.com/imesh-ai/webinar/tree/main/Istio%20Rate%20Limiting%20Simplified ▬▬▬▬▬ Additional resources ▬▬▬▬▬▬ ➡️ How to configure Istio local rate limiting: https://imesh.ai/blog/istio-rate-limiting-local/ ➡️ How to configure Istio global rate limiting: https://imesh.ai/blog/istio-rate-limiting-global/ ➡️ Learn Istio service mesh from scratch in 3 hrs: https://www.udemy.com/course/istio-service-mesh-hands-on-fundamentals-for-devops-and-sre/learn/ ➡️ Looking for Istio at scale, without any of its operational complexities?
