Hello
When you reach Maximum IOPS, provisioning less than 100 GiB of General Purpose SSD storage might result in higher latencies if you exhaust your I/O credit balance.
So How to Improve the IOPS: You find the link below there you can see a table of Provisioned IOPS and storage size range for each database engine, So if you increase size of the disk then you will get more IOPS it helps your application performance IOPS
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Storage.html
RDS Multi AZ:
In an Amazon RDS Multi-AZ deployment, Amazon RDS automatically creates a primary database (DB) instance and synchronously replicates the data to an instance in a different AZ. When it detects a failure, Amazon RDS automatically fails over to a standby instance without manual intervention.
So you will get failover but not IOPS by using this solution i think

EC2:
If you are using burstable instances it have baseline performance so it is recommended not use t type instance if you are using and remember that Ec2 instances also have the IOPS based on the storage if you will incrase the storage you will get more performance, You find information here https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volume-types.html

Hi @GK.
We are using multi-az. Will having high IOPS result in one of the instances failing and trigger failover ? Or will it just stay overloaded ?
