Open Telekom Cloud for Business Customers

Simple Message Notification (SMN)

Simple Message Notifications make your cloud landscapes more intelligent: individual resources can be enabled to exchange messages and even trigger actions, users can be informed of current statuses or send out mass mailing, and the messages can even be used to enable automation within a cloud. 

The Simple Message Notification (SMN) service in the Open Telekom Cloud offers three APIs for creating topics (a combination of a message and a logical access point), adding message subscribers, and sending out messages. It includes two central roles: publisher and subscriber. In contrast to the Distributed Message Service (DMS), a subscriber can also be external, e.g., an email address, a telephone number, a message queue or a URL. SMN is easy to integrate with other services and can thus act as an intermediary for data exchange. The service works using redundant message nodes: if one of the nodes fails, another one is used instead, ensuring that messages are transmitted reliably, regardless of how they are sent. SMN delivers these messages to various end points in a readable format (SMS, email, http/s). The SMN service itself is free of charge, but the activated follow-up actions generate costs.

Stability and reliability

Die Nachrichten werden in mehreren Datenzentren gespeichert und eine transparente Themenmigration wird unterstützt. Der SMN-Service speichert und liefert fehlgeschlagene Nachrichten erneut aus. Wenn ein Serviceknoten defekt ist, werden Ihre Anfragen automatisch von einem anderen verfügbaren Knoten bearbeitet.

SMN isolates data based on topics and does not allow any unauthorized users to access message queries, thereby protecting your service data.
