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.

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.
