An application uses an Amazon RDS MySQL DB instance. The RDS database is becoming low on disk space. A solutions architect wants to increase the disk space without downtime. Which solution meets these requirements with the LEAST amount of effort?
A.
Enable storage auto scaling in RDS.
B.
Increase the RDS database instance size.
C.
Change the RDS database instance storage type to Provisioned IOPS.
D.
Back up the RDS database, increase the storage capacity, restore the database and stop the previous instance.
https://aws.amazon.com/about-aws/whats-new/2019/06/rds-storage-auto-scaling/:
"Auto Scaling automatically scales storage capacity in response to growing database workloads, with zero downtime.
Previously, you had to manually provision storage capacity based on anticipated application demands. Under-provisioning could result in application downtime, and over-provisioning could result in underutilized resources and higher costs. With RDS Storage Auto Scaling, you simply set your desired maximum storage limit, and Auto Scaling takes care of the rest."
Answer is A
Answer is A.
https://aws.amazon.com/about-aws/whats-new/2019/06/rds-storage-auto-scaling/
Amazon RDS for MariaDB, Amazon RDS for MySQL, Amazon RDS for PostgreSQL, Amazon RDS for SQL Server and Amazon RDS for Oracle support RDS Storage Auto Scaling. RDS Storage Auto Scaling automatically scales storage capacity in response to growing database workloads, with zero downtime.
A.
Auto Scaling enables us to automatically scale up the capacity accordingly to the growing workload of the database with zero downtime. Before setting up RDS auto-scaling, we will build the RDS server with capacity and memory which is based on the application demands which we anticipate. If the workload is beyond our anticipation then we have to manually upgrade the capacity and memory of the RDS server which results in the application downtime.
B.Changing ec2 instance type(size) requires downtime
C.Changing the EBS type of ec2 will not help with less space issue.
IS it even possible to change this once ec2 is launched?
D.It says stop the instance->downtime involved.
