Today, AWS announces availability notifications for AWS Capabilities by Region in AWS Builder Center, a new subscription-based system that automatically alerts builders when an AWS service(s) and/or features(s) become available in their target Regions. Availability notifications make it easy for builders to track availability of 1,500+ services and features across 37 AWS Regions, accelerating infrastructure planning and deployment decisions.

With availability notifications, builders can subscribe at the service level through AWS Builder Center UI, and the subscription automatically covers all underlying features across selected Regions, so there's no need to track each feature individually. Notifications are delivered through two channels: instantaneous in-app alerts within AWS Builder Center, and a consolidated weekly email digest. Subscriptions and notification preferences can be managed through Settings > Notifications in AWS Builder Center. Common use cases include tracking a specific capability launch, monitoring service parity across AWS Regions, and preparing for upcoming migrations or Regional expansions. For example, a solutions architect expanding a generative AI application into new Regions can subscribe to Amazon Bedrock and receive automatic updates as Knowledge Bases, Guardrails, and other features become available.
