After terminal receives the access permission that business executes virtual machine, it would be desirable to the taskID of access service and corresponding visit
Ask that license is transmitted to virtual machine together, virtual machine verifies the legitimacy of the license after receiving, just allow after the completion of verification terminal-pair its
Business is operated.
In service inquiry, terminal sends access permission and to corresponding virtual machine node request data, and business is divided into
Task block of the same size, process are all task blocks that terminal concurrence returns to business.When reading the ending of a block, disconnect
To the link of virtual machine, then proceed to select next virtual machine to obtain next business datum.When terminal is directly connected to
When finding the inquiry of corresponding block progress business in virtual machine, check code can be verified first, detects whether read data have
Effect is directly read out if effectively, if in vain, needing to send out request to business execution virtual machine, to the virtual of backup
Data are read in machine node, and then valid data are synchronized to by backup virtual machine and are executed in virtual machine.
During business is submitted, virtual machine completes a series of verification work, confirms after allowing terminal to write business, to virtual
Machine sends out business datum and creates instruction, returns to the block address of terminal virtual machine.Then, terminal is established with virtual machine and is connected, and is asked
It asks and Business-to-Business is submitted to execute in the business datum that virtual machine is distributed, the address that can be actually submitted in virtual machine distribution block,
Setting offset ID, is divided into task block of the same size by business, concurrently uploads in the upload buffering of virtual machine.When completion is submitted
Afterwards, terminal can disconnect the connection with virtual machine.
After virtual machine receives the business to be committed of terminal, by the business of business asynchronous write backup virtual machine in order
In data, executes virtual machine and connect with backup virtual machine, submitted in backup virtual machine in the same way.Active and standby virtual machine is submitted
After the completion of, more new metadata, virtual machine deletes the submission caching that the business occupies.
Business executes virtual machine and is contacted with certificate server, and business is indexed in write-in directory system.If executed virtual
There are one being written in disk to fail from upload cache resources in machine or backup virtual machine, executes virtual machine and executed to business
Virtual machine request distributes another business datum and is written.By the method, after the verification of terminal identity twice, realize pair

Data execute business, then reattempt the virtual machine node application resource to mixed cloud, if applying successfully, directly carry out business
The storage work of data.
If the size of virtual machine node resource occupied by business is more than the vacant resource of virtual machine node, to mixed cloud
Virtual machine node application resource fails, while sending the transferable data cached order of transfer virtual machine node and sending business
Need the size of occupancy virtual machine node resource.
Mixed cloud is built with storage pool by introducing cache node, and is transferred to business datum according to Operational Visit frequency
Cache node or storage pool alleviate the caching of mixed cloud business datum to storing area resource great demand.
The step 2 preferably further includes：
It is sent out to virtual machine node since storage resource deficiency needed for business datum execution business needs to shift virtual machine section
The application of point resource；After virtual machine node receives the application that transfer logic unit is sent out, judge whether virtual machine node has
Transferable resource.If applying successfully, transferable resource size in virtual machine node is calculated by replacement policy.
If transferable resource size is more than or equal to business datum execution business and needs to occupy resource size in virtual machine node.
The transfer of mixed cloud based on cache node and storage pool is set according to the transferable data cached access frequency of virtual machine node
Address.
If transferable resource size is less than business datum execution business and needs to occupy resource size in virtual machine node, terminate
The transferable data cached transfer task of virtual machine node, and feed back the transfer transferable data cached failure signal of virtual machine node.
Wherein, after judging the transferable cache data access frequency of virtual machine node, if virtual machine node is transferable slow
Deposit data access frequency then reads cache node address and will read in the first pre-set business access frequency numberical range
Cache node address is set as jump address；First pre-set business access frequency numberical range is the transferable caching of virtual machine node
Data access frequency is higher, and specific access frequency range can be arranged by free terminal；If the transferable caching number of virtual machine node
According to access frequency in the second pre-set business access frequency numberical range, then the storage pool that stores pool address and will read is read
Address is set as jump address.
