AWS RDS cluster limit – Control your usage before service limits breach

AWS-RDS-Cluster_Service-Limits

Users need to be aware of their AWS RDS cluster limit for they can create in a particular region to make sure they have control over their usage before breaching limits. Service limits, if taken care of, can provide high availability and robust performance levels to your cloud infrastructure.

Why users need to be aware of their AWS RDS cluster limits?

Amazon RDS provides cost-efficient and resizable database capacity in the relational database which is of industry standards and also manages common database administration operations. An AWS RDS cluster is a collection of similar multiple RDS instances. You can use instances in a cluster for ‘read’ or ‘write’ operations. The configuration of database instances can, however, be changed according to the user’s requirement.

The default limit set for creating RDS clusters in a particular region via an AWS account is 40. There can be a situation where the user is creating clusters in a region without thinking of the cluster limit. If that limit is reached, further calls to create a cluster would fail with an exception. Breaching the limit defined for RDS clusters can also degrade the performance and health levels of your infrastructure.
