Pattern: Service mesh

Context

You have applied the Microservice architecture pattern and architected your system as a set of services.

Problem

You must implement numerous cross-cutting concerns including:

  • Externalized configuration - includes credentials, and network locations of external services such as databases and message brokers
  • Logging - configuring of a logging framework such as log4j or logback
  • Health checks - a url that a monitoring service can “ping” to determine the health of the application
  • Metrics - measurements that provide insight into what the application is doing and how it is performing
  • Distributed tracing - instrument services with code that assigns each external request an unique identifier that is passed between services.

Forces

Solution

Use a service mesh that mediates all communication in and out of each service.
