EventBridge is a serverless event bus that routes events at high throughput between Alibaba Cloud services and custom applications. It provides fully managed infrastructure with automatic scaling, built-in fault tolerance, and fine-grained access control.
Availability
High-throughput event delivery: Publish and consume large volumes of events without managing underlying infrastructure.
Automatic scaling: The serverless architecture scales resources on demand to handle burst traffic. No capacity planning is required.
Fault isolation: Stateless instances ensure that single-server failures do not affect the overall service, ensuring high service availability.
Multi-region deployment: Deploy across multiple regions to reduce network latency for geographically distributed workloads.
Dual-data-center redundancy: Each region runs across two data centers for strong disaster recovery and high data reliability.
Ease of use
Fully managed: EventBridge handles all deployment, operations, and maintenance. No infrastructure management is required.
CloudEvents 1.0 compatible: Fully compliant with the CloudEvents 1.0 specification, enabling seamless cloud migration.
Flexible access methods: Use the console, API operations, or Alibaba Cloud SDKs to interact with EventBridge.
Broad integration: Connect Alibaba Cloud services and custom applications.
Security
RAM-based access control: Grant fine-grained permissions to Resource Access Management (RAM) users through your Alibaba Cloud account. For details, see Grant permissions to RAM users.
Cross-account authorization: Create RAM roles and assign them across Alibaba Cloud accounts to share Alibaba Cloud resources between organizations. For details, see Grant permissions across Alibaba Cloud accounts.
Granular policies: Define different access permissions for different RAM users to enforce least-privilege access. For details, see Policies.
Transport security: Send requests over HTTP or HTTPS.
Scalability
Elastic event capacity: EventBridge automatically scales the capacity for sending events.
