Microservice Patterns

Architectures based on microservices introduce new challenges for architects and developers. New patterns emerge and existing are updated to be aligned to this relatively new architectural style.

This session presents 7 patterns commonly used in microservice based architectures. Each pattern will be in explained and demoed live in a down-to-earth and easy understandable way.
