Resizing Amazon EBS Volumes for Performance
In this hands-on lab, we will change the size of root EBS volumes on EC2 instances. This lab provides hands-on experience resizing volumes in standalone instances (a bastion host) and Auto Scaling groups (two web server instances). There are different reasons for a system administrator to have to resize a root volume. Needing larger storage capacity is the most obvious, but resizing is also necessary to increase the base IOPS of a volume. In this case, the volume may not be running low on storage space.
