Amazon Simple Notification Service (SNS)

Amazon Simple Notification Service (SNS) is a fully managed messaging service for both system-to-system and app-to-person (A2P) communication. It enables you to communicate between systems through publish/subscribe (pub/sub) patterns that enable messaging between decoupled microservice applications or to communicate directly to users via SMS, mobile push and email. The system-to-system pub/sub functionality provides topics for high-throughput, push-based, many-to-many messaging. Using Amazon SNS topics, your publisher systems can fanout messages to a large number of subscriber systems or customer endpoints including Amazon SQS queues, AWS Lambda functions and HTTP/S, for parallel processing. The A2P messaging functionality enables you to send messages to users at scale using either a pub/sub pattern or direct-publish messages using a single API.

Amazon API Gateway

Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. APIs act as the "front door" for applications to access data, business logic, or functionality from your backend services. Using API Gateway, you can create RESTful APIs and WebSocket APIs that enable real-time two-way communication applications. API Gateway supports containerized and serverless workloads, as well as web applications. API Gateway handles all the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls, including traffic management, CORS support, authorization and access control, throttling, monitoring, and API version management. API Gateway has no minimum fees or startup costs. You pay for the API calls you receive and the amount of data transferred out and, with the API Gateway tiered pricing model, you can reduce your cost as your API usage scales.

Azure Service Bus

Depend on Service Bus when you need highly reliable cloud messaging service between applications and services even when they’re offline. Available in every Azure region, this fully managed service eliminates the burdens of server management and licensing. Get more flexibility when brokering messaging between client and server with asynchronous operations along with structured first-in, first-out (FIFO) messaging and publish/subscribe capabilities. Leverage the power of asynchronous messaging patterns to reliably scale your enterprise applications. Integrate cloud resources such as Azure SQL Database, Azure Storage, and Web Apps with Service Bus messaging to get smooth operation under variable loads and the durability to survive intermittent failures. Improve availability by building messaging topologies with complex routing. Use Service Bus to deliver messages to multiple subscribers and fan out message delivery at scale to downstream systems.
