Thin Provisioning
Thin Provisioning is a smart way of managing computer storage space in data centers and cloud environments. Instead of allocating all storage space upfront, it only uses what's actually needed, similar to having a credit card limit but only being charged for what you spend. This approach helps companies save money and use their storage resources more efficiently. It's commonly used in virtual environments and modern storage systems. Other names for this concept include "dynamic provisioning" or "virtual provisioning."
