Issue
Is there a technique to reduce the size of windows EBS volume in our effort to reduce our running cost? I have seen some article on doing this for Linux but so far nothing for Windows.
Solution
No, it is not possible to reduce the size of an Amazon EBS volume because the operating system is responsible for organizing storage on the volume and doesn't like it when bits of the disk disappears.
It is possible to expand the size of a disk because the operating system can be told to expand the size of a partition without impacting existing data.
The only option is to create a new disk volume and copy the contents across. However, this can be tricky if it is a boot volume.
Amazon EBS is charged ~ $0.10 per GB-month of provisioned storage, so you need to weigh-up the time it would take to perform the change compared to how much money you are potentially saving.
