In a typical application, either run in a traditional datacenter or colocation facility, you’re paying for the application itself, the underlying OS, hypervisor, storage, servers or VMs, SAN, networking, power, and so on. Optimizing storage into frequently accessed hot storage, versus infrequently accessed cold storage.
