Keeping an eye on your AWS RDS service limits are as important as keeping intact the security aspect of RDS as they play a major role in impacting the scalability of your database resources in cloud.
How do you know that your service limit for RDS instances has breached?
Database instance being the basic element of RDS, a user can create multiple databases in that one single DB instance.
However, there is a limit on the number of RDS instances a user can spin up in a particular AWS region. You should be aware of such limits as it helps in the internal capacity planning of your cloud infrastructure. This could also help you in avoiding the wastage of resources.
