There is no denying the fact that many development efforts have to be spent on existing applications - legacy that is - which typically exhibit a monolithic design based on traditional tech stacks. Thus, affected companies strive to move towards distributed architectures and modern technologies. This talk introduces you to the strangler fig pattern, which aids a smooth and step-wise migration of monolithic applications into separate services. The practical part shows how to apply this pattern to extract parts of a fictional monolith into their own service by featuring:
* Apache Kafka, the de-facto standard for event streaming
* MongoDB and its official connector for Apache Kafka
* plus Debezium, a distributed open-source change data capture platform.
After this talk, you’ll have a better understanding of and a concrete blueprint for extracting functionality from your monoliths, thereby gradually evolving into a (micro)service architecture and an en vogue tech stack.
