# From Unreliable to Resilient: Mastering Distributed Systems

Description Distributed systems offer scalability and flexibility, but they also introduce new challenges: networks fail, messages get delayed, lost, or duplicated, and some operations - like sending an email - cannot easily be undone. Many real-world failures arise not from code bugs but from assumptions that no longer apply once a system spans multiple machines. In this workshop, you will see how patterns like Outbox and Inbox can help shape distributed workflows that are robust and reliable, allowing systems to maintain correctness and recover gracefully even when parts of the infrastructure fail. Key takeaway Reliable systems are built for unreliable environments.
