Krakow, Poland, 31 May - 2 June 2023
Many existing companies cannot just start over on the green field. Instead, significant maintenance efforts are necessary for aged applications, which usually exhibit a monolithic architecture based on traditional, potentially outdated tech stacks. Companies willing to shift towards distributed architectures and modern technologies are struggling because they don't know where and how to start.
This talk briefly introduces the strangler fig pattern, which enables a smooth and step-wise transformation of monolithic applications into separate (micro)services. The main focus of this practical session is a demo scenario, showing step-by-step how to extract a particular part of an existing monolith into a separate service. During the demo, we will also get in touch with popular technologies such as Kubernetes, Apache Kafka, Debezium, and MongoDB.
This session helps you to understand what it means to apply the strangler fig pattern to extract functionality from your monoliths. The learnings will empower you to gradually evolve existing applications into a (micro)service architecture and an en-vogue tech stack.
