If a school were suddenly closed for the day, students or parents could be told not come to school, or told to report to an alternate location. American Airlines can notify passengers by cellphone two hours before a flight's departure with information on the flight's status and gate number. When notification services are used for emergency notification, they are often called Emergency Mass Notification Services (EMNS).

Message Queuing Service
A message queueing service is a message-oriented middleware or MOM deployed in a compute cloud using software as a service model. Service subscribers access queues and or topics to exchange data using point-to-point or publish and subscribe patterns. It's important to differentiate between event-driven and message-driven (aka queue driven) services: Event-driven services (e.g. AWS SNS) are decoupled from their consumers. Whereas queue / message driven services (e.g. AWS SQS) are coupled with their consumers. Message queues can be a good buffer to handle spiky workloads but they have a finite capacity. According to Gregor Hohpe, message queues require proper mechanisms (aka flow controls) to avoid filling the queue beyond its manageable capacity and to keep the system stable. Ordering Guarantees in Message Queues Amazon SQS FIFO and Azure Service Bus sessions are queue-based messaging systems that provide ordering guarantees within a message group or session attempt but do ...
