This talk is distillation of what makes microservices different from normal services. While this talk can serve as an introduction to microservices the real goal is to help tease out the key areas of what is a very broard topic.

There has been lots of buzz around Microservices over the last year, but there has often been a lack of clarity as to what Microservices are, or how to implement them well. I've been working to distill down the principles of Microservices to help ensure that we don't just end up repeating the mistakes we made during the last 20 years of service oriented architecture. I'll talk about the history of where Microservices came from, what they are, the benefits and downsides, and the core principles to stick to do to them well.

This is a shorter 60min version of the presentation

  8. 8. @samnewman#ndcoslo Strategic Goals Architectural Principles Design and Delivery Practices Enable scalable business More customers/transactions Self-service for customers Support entry into new markets Flexible operational processes New products and operational processes Support innovation in existing markets Flexible operational processes New products and operational processes Reduce inertia Make choices that favour rapid feedback and change, with reduced dependencies across teams. Eliminate accidental complexity Aggressively retire and replace unnecessarily complex processes, systems, and integrations so that we can focus on the essential complexity. Consistent interfaces and data flows Eliminate duplication of data and create clear systems of record, with consistent integration interfaces. No silver bullets Off the shelf solutions deliver early value but create inertia and accidental complexity. Standard REST/HTTP Encapsulate legacy Eliminate integration databases Consolidate and cleanse data Published integration model Small independent Services Continuous deployment Minimal customisation of COTS/SAAS
