What are microservices ?

“Microservices are small, autonomus services that work together.”.

  • Small and focused on doing one thing well
  • Autonomous, services need to be able to change independently of each other

Key benefits ?

  • Resilience, if one component of a system fails, you can isolate the problem while the rest of the system can carry on working
  • Scaling
  • Ease of deployment
  • Organizational alignment, microservices allow us to better align our architecture to our organization
  • Composability, microservices can be consumed in different ways for different purposes
  • Optimizing for replaceability
