How does Azure Event Grid compare to Amazon EventBridge?

Both route events from cloud services and custom sources to handler targets. Event Grid uses a push model with topic subscriptions and supports CloudEvents standard natively. EventBridge uses rule-based routing with pattern matching and has broader built-in SaaS partner integrations. Azure Event Grid integrates deeply with Azure Functions and Logic Apps. EventBridge Pipes adds transformation and enrichment between sources and targets. Both are genuinely serverless with per-event pricing.

When should I use Kafka instead of EventBridge for event routing?

Use Kafka when events must be retained and replayable for hours, days, or indefinitely. EventBridge events are fire-and-forget with limited replay via Archive. Kafka enables multiple independent consumers to process the same events at different rates. For audit trails, event sourcing, or CQRS patterns requiring historical event replay, Kafka is architecturally more appropriate. EventBridge is simpler for lightweight, real-time routing without replay requirements.

What is Inngest and how does it differ from EventBridge for event-driven workflows?

Inngest provides durable function execution with built-in retry, concurrency control, fan-out, and step functions on top of an event trigger model. Where EventBridge routes events to stateless Lambda functions, Inngest manages multi-step workflows as durable processes that survive failures and wait for external events. It's closer to a durable workflow engine (Temporal) than a simple event router, making it appropriate for complex event-driven business processes.
