It's relatively easy to write and deploy a microservice these days, but no microservice is an island, and that's what slows you down. It turns out there are emergent patterns of modern cloud-first architectures which amount to "non-functional" requirements that you otherwise didn't have. Aspects of some problems are unsolvable (consistency, latency), but brittleness and manageability can be addressed with generic, boiler plate patterns, and that's the sort of stuff that you can end up re-inventing.

In this presentation we anatomise the common patterns of distributed systems and show how you can make life easier by employing off the shelf tools to address the problems you encounter (e.g. Netflix OSS and Spring Cloud).
