Service Meshes ● A service mesh is a dedicated infrastructure layer for making service-to service communication safe, reliable, observable and configurable ● Valuable as we move from deployment of complicated monoliths/services to orchestration of complex “cloud native” microservices and functions CLOUD COMMUNITY DAYS 

Sample Microservice Architecture CLOUD COMMUNITY DAYS 

CLOUD COMMUNITY DAYS Don’t microservices already do this? 

Traditional service-service communication ● Over REST or GRPC ● Manual Traffic Control Settings such as retry, timeout, circuit breaking, etc. ● Explicit Load balancing either client-side or server-side ● You may or may not service map ● All of this is repeated in every service in their way CLOUD COMMUNITY DAYS 

How does it work ? Array of network proxies CLOUD COMMUNITY DAYS 

CLOUD COMMUNITY DAYS • Automatic load balancing. • Fine-grained control of traffic behavior with routing rules, retries, failovers etc. • Pluggable policy layer. • Configuration API supporting access controls, rate limits and quotas. • Service discovery. • Service monitoring with automatic metrics, logs and traces for all traffic. • Secure service to service communication. With service mesh on your cluster, you can achieve:
