This document discusses service meshes for microservices. It describes the challenges of implementing common microservices patterns manually, such as service discovery and routing. A service mesh offers consistent approaches to these patterns without requiring a shared infrastructure component. Popular service mesh pioneers like Istio provide a control plane and data plane that intercept and manage traffic between services. While adding overhead, service meshes allow developers to focus on business code by handling concerns like tracing, security, and failure handling across the distributed system. The document outlines example architectures and invites attendees to future talks on related topics.

Implement our
own

6. Hard things happen
• Big Ball of Mud
microservice
• Hard to start
• Hard to debug
• Hard to deploy

7. How about this?

8. Any solution
so far ?

MESH offers
consistent
discovery, security,
tracing, monitoring
and failure handling
without the need for a
shared asset such as
an API gateway or
ESB.

12. Service Mesh - Pros and Cons
• Pros:
- Developers can focus on business code
- Solved most of the problems in MSA like distributed
tracing, logging, security, access control etc.
- Real polyglot approach, e.g. PHP, Java, .NET Core,
NodeJS, Golang,…
• Cons:
- Adding extra hops
- Immature
