Building application resiliency using load balancing

Load balancing is another technique to improve application resiliency. Istio load balancing policies help you maximize the availability of your application by distributing network traffic efficiently across the microservices or underlying services. Load balancing uses destination rules. Destination rules define the policy that controls how the traffic should be handled by the service after routing has occurred.

In the previous chapter, we used destination rules for traffic management purposes. In this section, we will go through various load balancing strategies provided by Istio and how to configure them using destination rules.

Deploy another envoydummy Pod but with an additional label of version:v2 this time and an output of V2----------Bootstrap Service Mesh Implementation with Istio----------V2. The config is available in Chapter5/envoy-proxy-02.yaml:

$ kubectl apply -f Chapter5/envoy-proxy-02.yaml
