ABSTRACT
Event driven architecture helps companies build highly scalable, distributed applications. By decoupling application integrations, applications become more durable and easier to manage. In this session, learn common integration patterns seen in the wild and how to decouple them. Discover how you can use AWS messaging services to connect microservices and coordinate data flow using minimal custom code.
Finally, you will learn how to reduce duplicate events and build in resiliency when your application has a failure by understanding and planning for idempotency. [...]

So good ❤

[@seNick7]

A routing logic inside EventBridge looks a bit like a long forsaken SOA's ESB. Btw: this is a very introductory talk.

5:54 oh goddammit

[@madmanX1314]

Dad jokes are great.

[@jorgetovar621]

EDA = something happen and we react :) really good!

[@aldhal202]

Not everything must be event driven or handled as fire and go. If there is a contract between 2 parties and services need immediate response or data or action, fire and go is the wrong choice for such scenarios

[@virtimus2]

For me "services need immediate response" generally by design ... 90% cases need just additional "wait state" ...
