Brief description
Fig. 1 is the rough schematic view of specific embodiment medium cloud system architecture.
Fig. 2 is the flow chart of the method that instance system exempts from installation and operation application in specific embodiment.
Specific embodiment
Below embodiments of the present invention are further illustrated.It should be noted that the scope of the present invention is not
It is confined to described concrete technical scheme.Any technology essential factor in described concrete technical scheme carried out identical or waits
Replace together the technical scheme obtaining or those skilled in the art on the basis of described concrete technical scheme without creation
Property the technical scheme that is obtained with of work, all should be contemplated as falling within protection scope of the present invention.
Certain operating system adds the necessary hardware (such as processor, memorizer etc.) running needed for this operating system, can
To constitute an instance system.Several instance systems are managed concentratedly according to certain framework mode, cloud system can be formed.
The operating system of instance system can be chosen for ARIXTRA (android) system.
In order to realize technical solution of the present invention, in cloud system, it is provided with control node, instance system and storage server three
Individual part, Fig. 1 is the rough schematic view of cloud system framework.Instance system and storage server are independent of one another, all by control node
Control and manage, the solid two-way arrow in Fig. 1 represents control and administrative relationships, dotted line four-headed arrow represents correspondence.Control
Node processed can be from the control server with x86 framework, and storage server is independent high-performance storage server, tool
There is higher configuration (such as 8 core processors, the big internal memory of 64g etc.).Control node, instance system and storage in actual cloud system
The quantity of server is far above one, for simple displaying, control node, instance system and each picture of storage server in Fig. 1
One.
Because storage server has very big memory space and the memory space of instance system is less, the use of cloud system
The application that family may need is stored in storage server.Storage server had both stored the installation kit of application, and also storing should
The all files that installation kit generates after installing.The quantity of documents that the installation kit of application generates after installing is often relatively more, and
And be frequently located in and under different file directorys, form certain TOC level relation, in technical solution of the present invention, these files are referred to as
For applying associated documents.Application associated documents pass through the operations such as duplication, packing, can form mirror image.The one of application associated documents
Individual complete mirror image not only includes all of application associated documents, and remains the TOC level relation of file.
Instance system exempts from the device of installation and operation application, and its core is provided in one of operating system of instance system
(this document system is hereinafter also referred to as hmfs to file system, and fs represents file system file system, and hm is a generation
Number there is no technical meaning), hmfs has the work(similar with common nfs (network file system, NFS)
Can, data can be obtained from network and return to vfs (virtual file system, the virtual file of native operating sys-tern
System), teledata is invented a catalogue on native operating sys-tern.But compare with nfs, hmfs also has many different
Function:
First, carry process needs the operating system partition accessing, the relief area that the write operation guiding of process is set.
Hmfs is capable of one or more subregions of carry operating system, and any process of carry back operation system is to these points
In area, the read-write of file is all controlled by hmfs.Hmfs sets a relief area on the correct position of instance system memorizer,
Process can be by the relief area of hmfs guiding setting to the write operation of file in the subregion of hmfs carry, and that is, write operation can not be repaiied
Change file itself, the data that write operation is simply changed by hmfs has been stored temporarily in the relief area setting.Angle from process
See, the subregion of hmfs carry is readable writeable, but the file actually in subregion is read-only file, after usual process is closed
Data in relief area can all be removed by hmfs.
Secondly, associated application associated documents.
As it was previously stated, what the write operation guiding of file in the operating system partition to its carry for the process can be set by hmfs
Relief area, but many times the subregion of hmfs carry is also the subregion that operating system runtime system process itself needs to access
(such as Android system /subregion such as data ,/cache), if hmfs is not added with the appointing any process in subregion of differentiation
The write operation of what file all guides the relief area of setting it is likely that causing operating system mistake even to collapse.Therefore, hmfs needs
Associated application associated documents, only process just guide, to the write operation of application associated documents, the relief area setting.If user needs
Run new application, hmfs can release and apply associating of associated documents before, associate new application associated documents.In order to keep away
Exempt from during disassociation produce mistake, hmfs release with apply associated documents can close its carry when associating by force
On operating system partition, all file handles being not turned off (will read data from a file, application first has to call operation system
System function simultaneously transmits filename, selects a path to this document to open file.This function fetches a serial number, i.e. file
Handle, file handle is unique basis of characterization for the file opened.).Now access these subregions, process if there are process
See is all empty list.
Process access during the subregion of hmfs carry it is seen that application associated documents be the virtual catalogue of hmfs, and apply phase
Pass file (hmfs searches and during the data in application associated documents, one complete mirror image of application associated documents is operated, this
In described application associated documents be actually a complete mirror image applying associated documents) be likely located at instance system locally,
It is likely to positioned at storage server.If it is only to read application associated documents that process does not carry out write operation to application associated documents
In data, when applying associated documents to be located at instance system local (certain position on instance system memorizer), hmfs is direct
In these files of local IP access, the data that process is needed returns to process by vfs；When application associated documents are located at storage clothes
During business device, hmfs passes through application associated documents from storage server for the network and reads data, then returns to process by vfs.
Hmfs can open a background thread, from storage server download application associated documents to instance system (if
If the memorizer of instance system has sufficient space), the data that such subsequent processes read in application associated documents can be at this
Ground solves, and no longer takies the Internet resources of cloud system.When searching the data in application associated documents, in order to be accurately positioned application phase
Close file, hmfs actually operates to a complete mirror image of application associated documents, therefore download application associated documents
To instance system, one that actually downloads application associated documents is completely mirrored to instance system.
Again, setting identification record process needs whether the data of the application associated documents reading is modified.
It may be necessary to constantly read data from application associated documents, these data have plenty of during process is run
Initial data in application associated documents, have is then the data that process was changed by write operation.Because hmfs is by process pair
The write operation of application associated documents has guided the relief area setting, and the data that process was changed has been actually stored in the slow of setting
Rush in area rather than application associated documents.This is accomplished by hmfs setting mark, and record the process needs the application associated documents reading
Data whether be modified so that hmfs can to process return correct data.Mark can (hmfs creates using bitmap
Build bitmap file, be modified with which data block in graphic recording application associated documents, data block is by reading and writing data
The least unit of operation) or other forms.
Because Android system is open source system, modification Android system source code can realize above-described
hmfs.
Exempt from the device of installation and operation application based on example discussed above system, it is possible to achieve instance system exempts from installation and operation
The method of application.The flow process that instance system exempts from the method for installation and operation application is as shown in Figure 2, comprising:
S201: file system, according to notifying to release and applying associating of associated documents before, associates the related literary composition of new application
Part.
Specifically, in this step, if the user of cloud system wishes to run new application, it is possible to use the mode such as client
Notify the control node of cloud system.After control node receives the notice of user, whether have time in the instance system checking its management
Not busy instance system, if it has, then transmitting control commands give idle instance system.The operating system of this instance system
(agent is a software for root (root) authority with operating system or program to agent, is responsible for the day of operating system
Ordinary affair are engaged in) according to control command, the application process run before closing simultaneously notifies hmfs.Hmfs releases with before according to this notice
The association of application associated documents, closes all file handles being not turned off on the operating system partition of its carry simultaneously by force.With
Afterwards, hmfs is according to the new application associated documents of this notice association.
S202: file system by process write application associated documents operational guidance set relief area, file system according to
Setting mark judge process need from application associated documents reading data whether be modified, the data not being modified from
Application associated documents read, and the data being modified reads from the relief area setting.
Specifically, in this step, after the new application associated documents of hmfs association, agent passes through ARIXTRA sdk (software
Development kit, SDK) notify zygote process to read application associated documents and open from/data subregion
Open art virtual machine process and run application.Each process is it is seen that hmfs is in/virtual application associated documents the mesh of data subregion
Record, process is taken over by hmfs to the read-write operation of application associated documents.If process carries out write operation to application associated documents,
The relief area that write operation guiding is set by hmfs, the data storage of write operation modification is in the relief area setting, and applies phase
Close file and do not have any change.If process carries out read operation to application associated documents, the mark first according to setting for the hmfs
Judge that process needs whether the data reading is modified before this, if process needs the data reading not to be modified, from
Read in application associated documents (i.e. file in a complete mirror image of application associated documents) and return to process；If process
Need the data reading to be modified, then read and return to process from the relief area setting, so can ensure that process obtains
Get correct data.
After s203: process is closed, file system removes the data in the relief area setting.
It appears that the process running application is readable writeable to application associated documents in step s202, but this is illusion, application
Associated documents will not have any change because process runs.In this step, if the process running application is closed, hmfs will be clear
Except all data in the relief area setting, so next application cannot obtain the operation information of an application when running.
Application operation information in may the private data containing user, be so provided with beneficial to protection user privacy, prevent reveal.
In technical solution of the present invention, due to hmfs the speed of service quickly, hmfs is between different application associated documents
Association switches in user it appear that what moment completed.In cloud system, network is typically all the LAN (such as 10,000,000,000 of function admirable
LAN), along with the cooperation of high performance storage server, even if application associated documents are located at storage server, if net
Within the specific limits, the speed that hmfs obtains data application associated documents from storage server even can surpass for network flow-control
Cross the speed reading data from local storage.Technical solution of the present invention is exempted from installation and operation application and is installed in instance system with applying
After rerun and compare, user application the aspect such as the speed of service all without experiencing difference, and exempt from installation and operation application effectively
Save and download installation kit and the application shared time is installed, greatly improve Consumer's Experience.If additionally, instance system
Memory space allows, and hmfs can will apply associated documents to download to instance system from storage server by background thread, after
The application of reforwarding row no longer takies the network traffics of cloud system.
Those skilled in the art, on the basis of concrete technical scheme described above, can construct its other party completely
Case.The operating system of such as instance system adopts other operating systems outside Android system, and the code of hmfs is carried out accordingly
Adjustment.Numerous to list herein.
