What is Message-Oriented Middleware with a Free Trial?

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.

IBM MQ

IBM

Massive amounts of data move as messages between applications, systems and services at any given time. If an application isn’t ready or if there’s a service interruption, messages and transactions can be lost or duplicated, costing businesses time and money to make things right. IBM has expertly refined IBM MQ over 25 years on the market. With MQ, if a message can’t be delivered immediately, it’s secured in a queue, where it waits until delivery is assured. Where competitors may deliver messages twice or not at all, MQ moves data, including file data, once — and once only. Never lose a message with MQ. IBM MQ is available as software to run in public or private clouds, in containers or on your mainframe. IBM also offers an IBM-managed cloud service (IBM MQ on Cloud) hosted on IBM Cloud or Amazon, and even as a purpose-built Appliance (IBM MQ Appliance) to simplify deployment and maintenance.

Amazon Simple Notification Service (SNS)

Amazon

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.
