vVolume Storage, 虛擬硬碟:
VM VM VM VM VM ... | Hypervisors | | HD Clients Server | | “Volume Storage Controller” a vitual hard disk drive (phisical array) that can be attached to VM instance to be used to host data with a file system. volume volume volume ... | | vStorage Controller | | Physical Storage Pool
-
Objective Storage, 物件存儲:
HD Clients Server | | “Objective Storage Controller” File Share Access Via API or Web Interface volume volume volume ... | | vStorage Controller | | Physical Storage Pool
it is a framework to build upon to develop an app. it is cost-effective, and quick way than real backend team.
-
DB Service:
Multi-Tenant, they can be access via API (direct call).
