What is a Service Mesh? Key Features, Benefits & Examples
· via Spacelift
Summary: Service meshes deliver mTLS, traffic control and telemetry without touching application code, at the price of running a mesh. The sidecar model is the core idea: proxies own the network so services do not have to. Below a certain service count the mesh costs more than it gives, and ingress plus libraries covers more cases than vendors admit.
Who should read it: teams at the microservices scale where network concerns repeat per service, and anyone evaluating Istio and friends.
