ABSTRACT
At Atlassian, we are in the midst of an architectural shift towards microservices to provide a scalable and flexible platform for our cloud services. In order to achieve this safely with no risk of losing customer data, we are investigating ‘event sourcing’ for representing our domain models i.e. capturing streams of immutable events to represent data instead of the traditional update-in-place paradigm.
With event sourcing, old versions of data can be easily restored and audit trails are available by default to help with debugging. In combination with the command-query responsibility separation (CQRS) pattern, we can seamlessly bring online new functionality requiring schema changes or new query patterns, and re-architect later for more scale simply by replaying and reinterpreting events into new microservices and ephemeral data stores.
In this talk, I will describe in detail what event sourcing and CQRS are, why we are using this approach, and a walk through of our implementation in Scala (leveraging scalaz-streams) in an AWS environment using #DynamoDB, #Kinesis and #Lambdas. [...]
