AWS re:Invent 2021 - Building next-gen applications with event-driven architectures

Many difficult problems in modern enterprise workloads can be solved with event-driven architectures. It can also be challenging to work with large amounts of data in different data stores and locations. Teams building microservices architecture often find that integration with other applications and external services can make their workloads more monolithic and tightly coupled. In this session, learn how to use event-based architecture to decouple and decentralize application components. You can use AWS messaging services to connect microservices and coordinate data flow, using minimal custom code.

The final part of the Taco Bell segment resonates. Serverless does make it easier to involve more people in a meaningful and productive fashion on a project.

Really cool to seeing Middy being mentioned here! 🎉

I would say the choreography approach (in this case) had poor cohesion rather than being too loosely coupled. It seems like the order process would need to have some sort of cohesive/centralized state to protect any invariants.  For instance, can an order ever be delivered before it's placed? Can an order be both cancelled and delivered? Can an order be delivered three times?


Out of curiosity, do you store the state of the order outside of Step Functions?

26:06 - If every message needs to call Database to check if it's duplicated, isn't it a limit of efficiency?
