Event-Driven Microservices: Beyond the Fairy Tale -- January 2023 Houston Java User Group Meeting
Показать описание
Our applications need to be faster, better, bigger, smarter, and more enjoyable to meet our demanding end-users needs. In recent years, the way we build, run, and operate our software has changed significantly. We use scalable platforms to deploy and manage our applications. Instead of big monolithic deployment applications, we now deploy small, functionally consistent components as microservices. Problem. Solved. Right?
Unfortunately, for most of us, microservices, and especially their event-driven variants, do not deliver on the beautiful, fairy-tale-like promises that surround them.
In this session, Allard will share a different take on microservices. We will see that not much has changed in how we build software, which is why so many "microservices projects" fail nowadays. What lessons can we learn from concepts like DDD, CQRS, and Event Sourcing to help manage the complexity of our systems? He will also show how message-driven communication allows us to focus on finding the boundaries of functionally cohesive components, which we can evolve into microservices should the need arise.
Finally, we'll walk the talk and put the code where the promises are. We'll take a small monolithic application and evolve it to microservices in mere seconds.
About the speaker:
Allard Buijze is Founder and CTO of AxonIQ. Starting at the age of 6, he has developed a great passion for programming and has guided both large and small organizations in building performant and scalable applications. Now, he is on a mission to make implementations of large scale systems easier, using the concepts of Domain Driven Design, Command-Query Responsiblity Segregation and Event Driven Architectures. He created Axon Framework as an experiment initially, but when both large and organizations started using Axon as a solution to their complexity problems, AxonIQ was born.
Through his conviction that good craftsmanship can only be achieved through continuous and intensive exchange of experience with others, Allard is a frequent speaker at conferences and meetups and enjoys giving trainings to fellow developers and architects. Allard is also regularly found in board rooms, explaining the concepts and values of DDD, CQRS and EDA to C-level executives.
