Loosely coupled services

Loosely coupled teams

“ One of the biggest changes is that we no longer have an official ‘architecture’ team. Instead, we have made ‘architecture’ an ‘ingredient’ on each of our teams.”

Coping with complexity remains a challenge

•  Cascading failures •  Circuit breaker •  Feedback loops

•  Monitoring changes •  Cattle v pets •  Queue depth, dependencies •  Self-healing infrastructure

•  Don’t NIH the platform

How? DevOps What? Microservices Why? Survival
