Azure Event Grid

Event Grid, available on Microsoft's Azure, is a single service for managing routing of all events from any source to any destination. It is designed for high availability, consistent performance, and dynamic scale.

The service is designed or used to:

• Eliminate polling—and the associated cost and latency. With Event Grid, event publishers are decoupled from event subscribers using a pub/sub model and simple HTTP-based event delivery, so as to build scalable serverless applications, microservices, and distributed systems.
• Build cloud applications - Gain massive scale, dynamically, while getting near-real-time notifications for changes. Build applications through reactive programming, capitalizing on guaranteed event delivery and the high availability of the cloud.
• Drive product innovation - Develop richer application scenarios by connecting multiple possible sources and destinations of events. Business logic can be triggered by virtually all Azure services, as well as custom sources. Fully managed event handling with delivery, intelligent filtering, and the ability to send events to multiple recipients at once allow you to focus on solving business problems rather than infrastructure.
• Streamline event-driven integration - Integrate workloads hosted on the cloud or Kubernetes using event-driven architectures in Event Grid. Event Grid resources can be managed on the cloud or Kubernetes using a single control plane on Azure.
