icloud shared storage

As one of the core services of cloud computing, storage services are used by every user. However, the current situation is: most customers in addition to virtual machine data disk (persistent disk), and does not fully utilize the storage services. Let's look at a typical scenario: for example, a Web application needs a user to upload an invoice scan (image file). At the code implementation level, the image
