Service Mesh
Definition
A service mesh organizes and monitors communication between individual software services.
An infrastructure layer for controlling, securing, and observing communication between services.
Simply explained
Like a shared traffic lane, it regulates how different parts of an application communicate with each other.
Why it matters in practice
The term contributes to secure, maintainable, and high-performance web applications as well as resilient technical decisions.
Example from business
A mesh enforces mTLS, traffic rules, and telemetry between internal services.
Limits and pitfalls
- Underestimating complexity, viewing the mesh as a substitute for application security, or overloading the data path.
Origin & history
Service meshes originated in microservice architectures and often use sidecar or ambient proxies.
Use in mid-sized companies
- Possible example: A mesh enforces mTLS, traffic rules, and telemetry between internal services.
