Getting Benefit From “The Async”, From a Circuit Breaker in a REST Architecture to an Orchestrated Saga

Over these years of my career I had the opportunity to experienced the architecture evolution from monoliths to microservices and most recently I had witnessed how event oriented solutions had became more relevant. During those years, being part of multidisciplinary teams, I had the opportunity to build architecture solutions to solve business needs of different nature, and make technical decisions understanding the trade offs involved. I would like to share some real examples of architectures we created with those teams where we got benefit from the sync”: a REST microservices solution where we used only a little piece of event oriented functionality to improve the end user experience and handle edge scenarios; and a second example of an orchestrated saga solution designed upfront following DDD principles to define the boundaries of each microservice. And finally how in both scenarios the technology choice provided a benefit considering the nature of the business problem.
