AWS RDS Event Subscription: Keep a tab on Limits

-

Are you aware of the service limits imposed by AWS? You need to monitor all the resources that you are consuming and make sure you do not exceed the provided limit.

AWS users cannot spin up resources in a particular region (or in general) beyond the capacity specified. This limit constraint is vital as it plays a major role in cloud resource management. RDS is one of the most commonly used AWS service. One of the resources that you can create and associate with DB instance is AWS RDS event subscription.

What are AWS RDS event subscriptions? Why event subscription service limit is important?

AWS RDS event subscription allows the user to get event notifications. These notifications can refer to various activities occurring in their cloud infrastructure related to their respective RDS resources such as DB instances, security groups, parameter groups. Some of the event categories for which the user can create a subscription are creation, deletion, configurational change, failure, low storage etc.

AWS RDS event subscriptions allow users to monitor their DB instances continuously and take necessary actions whenever a suspicious activity is detected. AWS has set a service limit of 20 RDS event notification subscriptions per region. Users should be aware of this resource limits so that they continue getting important notifications without any interruption due to exhaustion of resource limits.
