Amazon Simple Notification Service (Amazon SNS) now supports a higher default quota for subscription filter policies. With the increased quota, you can now have up to 10,000 subscription filter policies per account, and can apply up to 200 subscription filter policies per topic. By default, topic subscribers receive every message published to a topic. With subscription filter policies, subscribers can filter out unwanted messages, simplifying their architecture and optimizing the utilization of their resources.
Amazon SNS is a fully managed messaging service for both application-to-application (A2A) and application-to-person (A2P) communication. The A2A pub/sub functionality provides topics for high-throughput, push-based, many-to-many messaging between distributed systems, microservices, and event-driven serverless applications. The A2P functionality enables you to send messages to users at scale, via SMS, mobile push, and email.
