What do you think of when you hear "microservices?"
How do I design a system with microservices?
-
RESTful APIs
-
Autoscaling
-
Orchestration (Kubernetes, etc.)
-
Aggregated logging
-
Unified notification system
-
Integration testing
What about software architecture patterns?!?
Microservices basics:
Dev
Ops
Loose Coupling
A change to one service should not require a change to another.
High Cohesion
We want related behavior to sit together, and unrelated behavior to sit elsewhere.
Orchestration vs Choreography
Point-to-point connection between services
vs.
Each service is observing its environment (message bus) and acts on events autonomously

A confused deputy is a computer program that is innocently fooled by some other party into misusing its authority.
