AWS EventBridge
Serverless applications need a backbone and EventBridge is the backbone for AWS severless architecture.
Breaking a monolithic application down to microservices is only one step to modernizing applications for the public cloud. The application is still a monolith if the microservices are tightly coupled in a synchronized chain. Do you find yourself hardwiring error states from downstream services? You may have a monolith on your hands.
AWS Eventbridge is the message queue router for building distributed async applications. One of the things that I learned is that SaaS providers can integrate with Eventbridge. For example, MongoDB Atlas can publish to a customer’s Eventbridge enabling consumers such as Lambda to pick up and act on database changes.
