Planning for dynamic storage requirements requires that care be taken in determining the initial mount points or disk partitioning. The core operating system and application software should reside on statically sized block storage.
Additional block volumes can be added as additional mount points or drive letters under Windows for databases or applications requiring higher IOPS. Typically this storage can be increased, but not decreased readily on demand.
Additional object storage can be added as needed. Since object storage is only billed as it is used, you do not need to reserve storage or plan for changes down the road. Terabytes of object storage are there when you need it, on demand. Object storage is excellent for backups, archives or serving large amounts of static data from a web site.
Please see the Help Desk section Cloud Storage for more information on block and object storage.
