Demystifying Load Balancing in Istio - Shivanshu Raj Shrivastava, Independent & Jimmy Song, Tetrate

Istio is a widely adopted service mesh transitioning to the graduated project in CNCF. Multiple traffic management strategies are provided out of the box in istio by leveraging envoy proxy’s native APIs. Managing istio in a multicluster setup means a deep understanding of every istio config. As your production environment scales, your networking requirements change, and it's better to adopt new strategies to achieve resiliency in your networking infrastructure. A multicluster setup may become complex, you may want to introduce a mixture of gateways routing to multiple clusters and then routing to services; configuring layer 4-6 load balancing effectively can help you leverage most out of your infrastructure. We aim to discuss different load-balancing strategies available in istio, such as locality load balancing and other algorithms available and demonstrate via demos when and how to leverage each of the load-balancing strategies to get the most out of your distributed infrastructure.
