AWS ElastiCache - SNS Notifications


Advertisements


AWS SNS stands for simple notification service. It is used to fan out messages to a large number of subscriber endpoints for parallel processing. For example, used to fan out notifications to end users using mobile push, SMS, and email. We can send messages about important cluster events like, CPU or memory utilization etc., to various subscribers. So that we can keep track of the health of ElastiCache.

Configuring SNS is a straight forward process. Below are the steps we take to configure the SNS topics.

Identify the Cluster

Login to the AWS account and navigate to the ElastiCache dashboard. ­Next, choose the relevant engine, either Redis and Memcached. Next, choose the name of the cluster in which the SNS service has to be assigned. The below screen represents an example of such a cluster.
