Service Mesh
A dedicated infrastructure layer for handling service-to-service communication in microservices. Manages load balancing, encryption, and observability automatically.
What is Service Mesh?
A dedicated infrastructure layer for handling service-to-service communication in microservices. Manages load balancing, encryption, and observability automatically.
Service Mesh is a intermediate-level concept that sits in the Microservices Architecture area of system design. Engineers reach for it whenever they need to reason about real-world trade-offs in that space — not just for textbook correctness, but because real production systems at companies like Netflix, Amazon, and Google make these decisions every day.
If you want to go deeper than this definition — with diagrams, code, and a quiz to lock it in — work through the "Service Mesh" lesson linked below. It walks through the why, the mechanism, the trade-offs, and how the giants actually use it in production.

Microservices
An architecture where an application is split into small, independent services that communicate over the network. Each service owns its own data and can be deployed separately.
Service Discovery
The mechanism by which microservices find and communicate with each other. Services register themselves and others can look them up by name.
Kubernetes
An orchestration platform that automates deploying, scaling, and managing containerized applications. K8s is the operating system for your cloud.
