In today’s competitive digital landscape, having a system that captures and audits each action is essential. Traditional data storage approaches focus on keeping only the latest state of data, leaving out the historical trail that led to that state.

Implementing event sourcing in a microservices architecture can be challenging, but the Axon Framework, a Java-based tool, simplifies the process. This article dives into how Axon Framework helps you implement event sourcing effectively, covering best practices, code examples, and solutions to common challenges.
