Simple Message Notification (SMN)

Simple Message Notification (SMN) provides a Pub/Sub service for cloud applications and services, enabling you to send messages to various endpoints.

20+ Regions

SMN is available in 20+ regions around the world, including Asia Pacific, Latin America, and Africa.

10+ Protocols

You can send messages to various endpoints via protocols, such as email, SMS, HTTP, HTTPS, and FunctionGraph (function).

60+ Cloud Services

More than 60 Huawei Cloud services use SMN to send messages.

Why Huawei Cloud SMN?

Fast Message Delivery with Simple APIs

You can efficiently send messages by calling three easy-to-use APIs for topic creation, subscription, and message publishing.
Topics help you separate message publishers from subscribers. Messages are sent asynchronously.
In addition to delivering messages to multiple subscribers over different protocols at once, you can also define message formats for different protocols.

Reliable Message Cache, Delivery, and Retries

SMN stores each message published across multiple data centers for high availability. SMN itself is deployed in clusters and across AZs.
SMN provides redundancy across multiple SMS gateways, ensuring timely and reliable delivery of your messages.
If a message delivery fails, the failed message will be cached and delivered again up to six times before it expires.
Messages are isolated between tenants and do not affect each other.

Flexible and Efficient Message Delivery over Multiple Protocols

With a single messaging request, you can deliver messages to subscribers using a range of protocols, including email, SMS, voice, HTTP, HTTPS, functions, workflows, and WeCom, DingTalk, WeLink, and Lark chatbots.

Event Notifications over Multiple Protocols

If you need to send Cloud Eye event alarms of different severities to different endpoints, such as an email address, phone number, or instant messaging chat group, SMN is recommended.

Advantages

Simple and Efficient

After you add subscribers of different protocols to the same topic, messages can be delivered to them all with a single request.

Secure and Reliable

Messages are sent only to subscribers who have confirmed subscriptions.

Integration with Cloud Services

With SMN, you can send messages generated by a cloud service to other cloud services. For example, you can configure SMN to notify FunctionGraph of object events in an OBS bucket.

Advantages

Automatic

SMN connects cloud services and automatically invokes their functions through messages.

Simple and Efficient

There is no need to develop your own messaging system. With just a single SMN API, you can send messages over multiple protocols.

Traffic Control

If there is a discrepancy between processing capabilities of the upstream and downstream systems, SMN can cache data to reduce downstream pressure.

Advantages

High Availability

SMN reduces system breakdowns and complexity and enhances availability.

Optimized Message Processing

SMN enhances system capabilities to process messages faster during peak hours.

Continuous Innovation with Millions of Customers

Meitu SF Technology MINOVATE

Notify Cloud Resource Changes Using Huawei Cloud SMN

Meitu manages all its cloud and on-premises IT resources through an in-house CMDB. Huawei Cloud Config tracks Meitu's cloud resource changes and calls SMN to send notifications to Meitu CMDB over HTTPS.

Boost Operations Efficiency with Huawei Cloud SMN

Based on different alarm severities, SF Technology uses SMN to notify O&M personnel of events by email, SMS, or voice, improving O&M efficiency.

Make O&M Easier with Huawei Cloud SMN

SMN forwards alarm notifications to the Lark groups of MINOVATE at once, instead of notifying each O&M member one by one. Even if there is a personnel change, members in the Lark group will always receive relevant alarm notifications. There is no need to manage message recipients on the Huawei Cloud Message Center.
