Amazon EventBridge expands support to all Regions, except for AWS GovCloud (US) and China, as a destination for its cross-Region event bus as a target functionality launched in April’2021 (initially launched with 3 destination Regions - US East (N. Virgina), US West (Oregon) and Europe(Ireland)). This will allow customers to consolidate events in one central Region from any Region. This makes it easier for customers to centralize their events for auditing and monitoring purposes or replicate events from source to destinations Regions to help synchronize data across Regions. 

EventBridge is a serverless event bus that enables you to create scalable event-driven applications by routing events between your own applications, third-party SaaS applications, and other AWS services. You can set up routing rules to determine where to send your data, allowing for application architectures to react to changes in your data and systems as they occur. Amazon EventBridge can make it easier to build event-driven applications by facilitating event ingestion, delivery, security, authorization, and error handling. 

With cross-Region Event Bus target support, customers can now have their event information in the destination Region. This makes it easier for developers to find those events and write code that reacts to them, and generate insights from events generated across the organization. 

To enable cross-Region event bus targets, you need to specify the Amazon Resource Name (ARN) of the event bus in the destination Region. You can use this to send events within the same or a different account across Regions. You can get started using the AWS Management Console or using the APIs. You pay as per the custom events pricing for cross-Region invocations. To learn about pricing, please visit the EventBridge pricing page.

You can now send events between any of the following AWS Regions: US East (Ohio), US East (N. Virginia), US West (Oregon), US West (N. California), Canada (Central), Europe (Stockholm), Europe (Paris), Europe (Ireland), Europe (Frankfurt), Europe (London), Europe (Milan), Middle East (Bahrain), Africa (Cape Town), Asia Pacific (Mumbai), Asia Pacific (Tokyo), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Hong Kong), Asia Pacific (Osaka), Asia Pacific (Sydney), and South America (São Paulo).
