Reactive Summit 2017

So you're going to build a microservice system. And this is not just any system. This system is going to process a ton of traffic, and it cannot go down - no excuses! This session covers techniques and tools that you can use to scale individual microservices up or down as traffic rates change. We also look at hardening your system eliminating single points of failure and automatically recovering when various outages occur. The cornerstone of this approach is Event Sourcing and CQRS (Command Query Responsibility Segregation). ES and CQRS provide the platform for both scale and resilience. We will see how this is done using Java, the Akka toolkit, the Play framework, and the Lagom microservice framework.
