New conference talks on asynchronous microservices: implementing Sagas and CQRS (#GotoChgo, #microcph)
I recently gave talks at a couple of conferences.
GOTO Chicago - Not Just Events: Developing Asynchronous Microservices
The first talk was at GOTO Chicago. This talk described how to solve distributed data management problems in a microservice architecture using asynchronous messaging. I described how to implement transactions using the Saga pattern and implement queries using the CQRS pattern. Both patterns rely on asynchronous messaging between services.
MicroCPH - Managing data consistency in a microservice architecture using Sagas
My second talk was at MicroCPH in Copenhagen, Denmark. It focussed on implementing transactions that span services using the Saga pattern
