Event Mesh
ELI5 — The Vibe Check
An event mesh is like a postal system for events that knows every address across all your clouds and data centers. Events find their way to the right consumers no matter where they live — it's a service mesh, but for events instead of requests.
Real Talk
A dynamic infrastructure layer that routes events between producers and consumers across distributed environments (multi-cloud, hybrid, on-premise). Unlike a single message broker, an event mesh connects multiple brokers into a unified network with intelligent routing, filtering, and protocol bridging.
