Hub-and-spoke, point-to-point, event-driven, and microservices integration patterns: when to use each and how to decide.
Every enterprise has a dozen or more software systems that need to share data. The architectural pattern you choose for connecting them determines how easy it is to add new systems, how resilient the whole thing is to failures, and how much it costs to maintain. Choose well and integrations hum along quietly. Choose poorly and your team spends half its time debugging broken connections.
There's no single "best" pattern. Each has tradeoffs, and the right choice depends on your systems, your team, and your scale. Let's examine each pattern so you can make that choice intelligently — and prompt your AI agent to build within the right architecture.

Each system connects directly to every system it needs to communicate with. System A calls System B's API. System
