Presentation: Managing Data in Microservices

This session is about the hard stuff -- managing data in microservices -- and about sharing proven patterns that have been successful at Google, eBay, and Stitch Fix. It begins with a quick tour of some prerequisites for being successful with microservices -- an organization of small teams with well-defined areas of responsibility; processes for test-driven development and continuous delivery; and a DevOps culture of "You Build It, You Run It."

The majority of the session is spent on managing data. It covers the need to isolate a microservice's data store behind the service interface, as well as the various persistence mechanisms for managing data. It discusses using events as a first-class tool in our architectural toolbox. It covers techniques for service extraction from a monolithic database. Then it composes those building blocks to build up patterns for handling shared data, joins, and transactions in a microservice world.

It concludes with lessons learned, as well as suggestions for how you can implement these ideas successfully in your own organization.
