Amazon SNS

Purpose: Amazon SNS is a fully managed Pub/Sub service for application-to-application and application-to-person messaging.
Delivery: SNS delivers notifications to application endpoints and to people through SMS, mobile push, and email.
Standard topics: Standard topics support nearly unlimited messages per second, best-effort ordering and deduplication, and up to 12.5 million subscriptions per topic.
FIFO topics: FIFO topics preserve message order, prevent duplicate delivery within a five-minute interval, and support up to 3,000 messages per second or 10 MB per second per topic.
Integrations: SNS has native integrations with AWS event sources and destinations, and supports endpoints including Amazon SQS, Amazon Data Firehose, AWS Lambda, and HTTPS.
Filtering and batching: Publishers can batch 1 to 10 messages per API request, and subscribers can use filter policies to receive selected notifications.
Message size: Each message can contain up to 256 KB; the SNS Extended Client Library can store payloads up to 2 GB in Amazon S3 and publish an object reference.
Durability: SNS stores published messages across geographically separated servers and data centers, retries delivery, and supports dead-letter queues for undelivered messages.
Encryption: Encrypted topics use server-side 256-bit AES-GCM encryption with a key issued by AWS Key Management Service.
Private networking: SNS supports AWS PrivateLink VPC endpoints to publish to topics without traversing the public internet.
Mobile push: SNS mobile push supports iOS, Android, Fire, Windows, and Baidu devices through providers including APNs, Firebase Cloud Messaging, and Amazon Device Messaging.
SMS reach: SNS supports SMS messaging to over 200 countries and offers redundancy across multiple SMS providers.
Compliance: Amazon SNS is listed as in scope for AWS SOC 1, 2, and 3 reports; AWS says customers remain responsible for their applicable compliance obligations.
Who it serves: AWS says its customers include startups, enterprises, non-profits, and governments.
