What is Message-Oriented Middleware?

Message-oriented middleware (MOM) is software that provides an interoperable interface between multiple applications. It enables applications to communicate with one another, regardless of their underlying technologies. Applications using MOM can send and receive messages across a variety of networks and transport protocols such as HTTP, TCP/IP, and SMTP. These messages can be either synchronous or asynchronous, allowing for real-time interactions or delayed messaging without the need for complex programming code. MOM also facilitates remote access through a centralized system making it easier to manage in distributed environments. Additionally, since it is independent of the application architecture, MOM offers increased flexibility when integrating different platforms together.

    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.

    Huawei Simple Message Notification (SMN)
    Simple Message Notification (SMN) enables you to broadcast messages to email addresses, phone numbers, and HTTP/HTTPS servers and connect cloud services through notifications, reducing system complexity. Efficiently sends messages with three easy-to-use APIs for topic creation, subscription, and message publishing. Saves messages in multiple data centers to achieve high availability. If a message delivery fails, the failed message will be cached and delivered again. Enables you to deliver messages to subscribers using various protocols with only one messaging request. Isolates data by topic. Unauthorized users cannot access your message queues, ensuring service security. Use messages to connect other cloud services, achieving system decoupling and ensuring reliability. If one service becomes faulty, messages sent to other services will not be adversely affected. Connects cloud services and automatically invokes their functions through messages.
