Service Mesh
An infrastructure layer that handles communication between microservices.
Detailed Explanation
A service mesh is a dedicated infrastructure layer that controls service-to-service communication, often implemented via sidecar proxies. It abstracts away retries, encryption, observability, and load balancing from the application code.
Why It Matters
As microservice architectures grow, managing network policies and mutual TLS inside the application code becomes an unmaintainable nightmare. A mesh shifts this burden to the infrastructure.
Common Failure Mode
Practical Example
Production Manifestation
A sidecar container running next to every pod in a Kubernetes cluster, intercepting all network traffic to enforce security policies and generate distributed tracing telemetry.
Frequently Asked Questions
What is Service Mesh in short?
An infrastructure layer that handles communication between microservices.
What is the most common failure mode?
Introducing a complex service mesh into a small architecture prematurely, resulting in operations teams spending more time debugging the mesh configuration than the actual application.
