Event Grid
Azure Event Grid is a fully managed publish-subscribe messaging service designed to power event-based applications. It enables communication with MQTT clients, allowing developers to build reactive systems that respond to specific events. This service falls under the broader category of messaging solutions within the Microsoft Azure cloud platform, facilitating efficient data flow between disparate components.
Choose this service when you need a managed solution for event-driven architectures without managing underlying infrastructure. Be aware that there is no free tier available, meaning you will incur costs from the start. The pricing model operates on a pay-as-you-go basis, so usage volume directly impacts your monthly bill without any initial free allowance to offset early testing expenses.
