Service Meshes- The Ultimate Guide
3 likes293 views
The document provides an ultimate guide to service meshes, which manage service-to-service communication in distributed systems using sidecar proxies. Key benefits of service meshes include dynamic service discovery, traffic management, security, and observability, but they also introduce complexity and resource demands. Popular service meshes like Linkerd and Istio, as well as associated technologies such as Envoy and Kiali, are highlighted, along with a timeline of significant developments in the space.

- 3. A service mesh manages all service-to- service communication within a distributed (potentially microservice- based) software system. It accomplishes this typically via the use of “sidecar” proxies that are deployed alongside each service through which all traffic is transparently routed. KEY TAKE AWAY NO 1 I N F O Q .

- 4. Proxies used within a service mesh are typically “application layer” aware (operating at Layer 7 in the OSI networking stack). This means that traffic routing decisions and the labeling of metrics can draw upon data in HTTP headers or other application layer protocol metadata. KEY TAKE AWAY NO 2 I N F O Q .

- 5. A service mesh provides dynamic service discovery and traffic management, including traffic shadowing (duplicating) for testing, and traffic splitting for canary releasing, incremental rollout, and A/B type experimentation.

- 6. A service mesh also supports the implementation and enforcement of cross cutting requirements, such as security (providing service identity and TLS) and reliability (rate limiting, circuit-breaking).

- 7. As a service mesh is on the critical path for every request being handled within the system, it can also provide additional “observability,” such as distributed tracing of a request, frequency of HTTP error codes, global and service-to-service latency.

Service mesh technology is rapidly becoming part of the (cloud native) application platform “plumbing.” The interesting innovation within this space is happening in relation to the higher-level abstractions and the human-focused control planes.

Supporting technologies within this space include: Layer 7-aware proxies, such as Envoy, HAProxy, and NGINX; and service mesh orchestration, visualization, and understandability tooling, such as SuperGloo, Kiali, and Dive.
