EventBridge
EventBridge is a serverless event bus service provided by Alibaba Cloud within its developer tools category. It functions as a centralized hub for connecting applications and services by routing events. This allows developers to build loosely coupled architectures where components communicate through asynchronous messages rather than direct calls, facilitating scalable and flexible system designs without managing underlying infrastructure.
Choose this service when you need a managed, serverless solution for event routing that scales automatically with your workload. Be aware that there is no free tier available for EventBridge, meaning all usage incurs costs immediately from the start. The pricing model operates on a pay-as-you-go basis, so you will be billed strictly for the resources consumed during event processing and transmission.
