## Overview
|
||
**Amazon EventBridge** 是 AWS 的无服务器事件总线服务，用于构建事件驱动的架构。它可以接收来自 AWS 服务、SaaS 应用程序和自定义应用程序的事件，并根据定义的规则路由到目标。本方案中 EventBridge 作为跨账户事件转发的核心组件。
|
||
|
||
## Key Capabilities
|
||
- **Event Bus**：默认事件总线和自定义事件总线
|
||
- **Event Rules**：基于事件模式匹配捕获特定事件
|
||
- **Cross-Account Event Routing**：跨账户事件转发（该方案的核心功能）
|
||
- **Event Filtering**：基于内容的事件过滤
|
||
- **Schema Registry**：事件模式注册和管理
|
||
|
||
## In This Solution
|
||
EventBridge 在多账户 CloudFormation StackSets 监控方案中的角色：
|
||
1. **事件捕获**：在每个成员账户部署 EventBridge Rules，捕获 CloudFormation 事件
|
||
2. **跨账户转发**：通过 Event Bus 的跨账户访问策略，将事件转发到管理账户的 Custom Event Bus
|
||
3. **路由到 CloudWatch**：管理账户 Event Bus 将事件路由到 central-cloudformation-logs Log Group
|
||
|
||
## Event Flow
|
||
```
|
||
Member Account: CloudFormation event
|
||
→ EventBridge Rule (pattern match)
|
||
→ Event Bus (custom, member account)
|
||
→ [Cross-account permission via IAM]
|
||
→ Event Bus (custom, management account)
|
||
→ CloudWatch Logs (central-cloudformation-logs)
|
||
```
