Integrations are the glue that holds modern systems together. At first glance, building an integration to an external system - or even linking internal services - can seem deceptively simple. Unfortunately things are never as straightforward as they seem. Systems become unresponsive, networks fail, and unexpected edge cases lurk around every corner.

In this talk, we’ll dive into real-world examples and practical techniques for building integrations that play nicely - even when the world around them doesn’t.

Whether you're integrating with third-party APIs, internal services, or legacy systems, this talk will give you an overview of what's needed to build resilient, well-behaved integrations that last.

A conference talk by the head of development at Parkster, a parking app handling hundreds of thousands of daily transactions, covering practical strategies for building resilient service integrations. Topics include pre-integration planning (shared vocabulary, communication channels, responsibilities), the transactional outbox and inbox patterns for eventual consistency, timeout handling with real-world anecdotes, retry strategies with exponential backoff and jitter, idempotency keys, dead letter queues, circuit breakers, and bulkheads. The talk also emphasizes observability through metrics and alerts, and building a blameless culture that treats failures as learning opportunities.
