Microsoft recently released the public preview of Azure Event Grid – a hyper-scalable serverless platform for routing events with intelligent filtering.

• Azure Functions – Serverless compute
• Logic Apps – Serverless connectivity and workflows
• Service Bus – Serverless messaging
• Event Grid – Serverless Events

And as Tord Glad Nordahl says in his post From chaos to control in Azure, “With dynamic scale and consistent performance Azure Event grid lets you focus on your app logic rather than the infrastructure around it."
