Frequently asked questions

What is a service mesh and what problems does it solve?

A service mesh is an infrastructure layer designed to manage communication between services in a microservices architecture, addressing challenges like observability, security, and traffic management.

How does a service mesh improve the security of my microservices?

Service meshes enhance security by enabling mutual TLS (mTLS) for secure communication between services, along with granular access control policies to restrict network traffic.

What is mTLS and why is it important in a service mesh?

mTLS stands for Mutual Transport Layer Security, which provides strong encryption and authentication for communication between services within the mesh, significantly improving security.

Can you explain how a service mesh impacts application performance?

While service meshes introduce some overhead – typically less than 1ms per hop and memory usage from sidecar proxies – they are designed to minimize latency and provide granular control for optimizing application performance.
