Why you need this guide

As systems grow more distributed and data flows become more complex, traditional persistence models start to reveal their limits. Whether it's debugging inconsistencies, meeting audit requirements, or understanding what happened and when — conventional databases and message brokers fall short.

This guide introduces a better way to persist and reason about your system’s state: event sourcing. You'll learn why it matters, when to use it, and how to get started — even in existing systems.

  • Legacy systems break under scale
    Understand how traditional models create long-term complexity.

  • Message brokers ≠ system memory
    See why messaging isn’t enough when state history matters.

  • Event sourcing explained clearly
    Learn the core principles through simple, real-world examples.

  • Built for developers
    No theory-only fluff — this guide is packed with actionable, technical content.

  • Future-proof your stack
    Find out how to design systems ready for tomorrow’s challenges.

Frequently Asked Questions

Q: What is event sourcing in simple terms?

A: It’s a way of storing all changes as a sequence of events — not just the latest state. This lets you rebuild and analyze your system’s history at any point.

Q: Why should I care about event sourcing in 2025?

A: Because modern systems demand full traceability and resilience. Event sourcing provides powerful debugging, auditing, and recovery capabilities.

Q: Isn't event sourcing difficult to implement?

A: Not with the right tools. This guide shows how Axon Framework and Axon Server help you get started quickly — without complex infrastructure.

Q: Do I need Axon to apply these ideas?

A: No. The principles in this guide are tool-agnostic. But Axon accelerates implementation and simplifies complexity.

Q: Is this whitepaper really free?

A: Yes. No hidden costs, no catch. Just valuable, expert-driven insights to help you modernize your architecture.
