Microservices: Lessons from the Trenches

Microservices are all the rage. They are the silver bullet of architectural styles. But what does it take to implement them and make them work? What are the foundations to build using this architectural style. In this session, you will learn about microservices from a pragmatic standpoint, based on about 2 years of experience in consulting on the architectural style. Rather than look at the purist approach, as outlined by Martin Fowler, and others, you will learn what works and what doesn’t, based on experience in the field.

Session includes
* Foundational topics necessary to implement microservices
* Basics on the architectural style as they apply to real world problems.
* Necessary It and shifts to implement microservices in the Enterprise
