  • Developers and architects

What you'll learn

  • Understand the challenges of distributed systems, simple strategies and frameworks to help, and concrete source code examples to use as starting point

Description

Integrating microservices and taming distributed systems is hard. Most people still integrate via REST but are not even aware of missing consistency guarantees in these architectures. Bernd Rücker shares three challenges he’s observed in real-life projects and demonstrates how to avoid them, using live coding.

Challenges include:

  • Communication is complex. When everything is distributed, failures are normal, so you need sophisticated failure handling strategies (e.g., stateful retry).
  • Asynchronicity requires you to handle timeouts. This is not only about milliseconds; systems get much more resilient when you can wait for minutes, hours, or even longer.
  • Distributed transactions cannot simply be delegated to protocols like XA. You need to solve the requirement to retain consistency in case of failures.
