> SQS: Simple Queue Service
|
||
|
|
|
||
|
|
SQS is a service that allows you to send, store and receive messages between apps and software components built in AWS, with automatic encryption. It helps with decoupling and scaling.
|
||
|
|
|
||
|
|
As the name indicates, its operating mode is that of a [queue](/Data_Structures/Queue.md) data structure offering first-in, first-out and other queue implementations.
|
||
|
|
|
||
|
|
An example application of this would be to set up an SQS queue that receives messages and triggers a lambda whenever a new message is added.

## SNS

|
|
> SNS: Simple Notification Service
|
||
|
|
|
||
|
|
Similar to SQS but the focus is on notifications rather than messages, i.e events that fire when something specific happens, not just a message-send event. It can be used for passing notifications between applications or to persons through SMS, text, push notifications and email.
