Embodiment

Basic thought of the present invention is: cloud storage system receives the access request that user sends by the web browser of client; Cloud storage system moves static page according to the page type of described access request access and separates, and the access request of the access request of the access static page and access dynamic page is distributed to different web page servers; Web page server is mapped to physical server by the access request receiving and carries out page documents processing.

Below by drawings and the specific embodiments, the present invention is described in further detail.

The present invention realizes a kind of cloud storage means of accessing by webpage mode, and as shown in Figure 1, the method comprises following step:

Step 101: cloud storage system receives the access request that user sends by the web browser of client;

Described access request is generally Http request.

Step 102: cloud storage system moves static page according to the page type of described access request access and separates, is distributed to different web page servers by the access request of the access request of the access static page and access dynamic page;

Because needs carry out interactive operation with client, therefore in Web page system, not only there is a large amount of static Web page pages, also exist a large amount of dynamic web page pages, the described static Web page page is as HTML (HTML) page, the described dynamic web page page is as JSP, the pages such as servlet, if static state and dynamic page unification are put into active server page, in tomcat server, probably cause the hydraulic performance decline of active server page, its reason is that active server page is that the dynamic web page page carries out flow processing by unified the static Web page page treating as, there is during this time the operation of redundancy, as except resolving html text, also need to carry out the process of analysis of other dynamic script, as the JSP page is resolved, it is except resolving the code of HTML part, also need JSP script wherein to resolve to java code, be class false code by java code analysis again, this very big degree has been wasted system resource,

For the client access performance taking into full account, need in advance the Webpage of two types be deployed on different web page servers and be processed, as: the static Web page page is deployed on static Web page server, on Apache Server, the dynamic web page page is deployed on active server page, on tomcat server, by judging that current access request is which kind of types of web pages page of access is distributed on earth;

This step is specially: cloud storage system is resolved the access request from client terminal web page browser, according to the suffix of the URL address of the page of described access request access, determine the page type of access request access, the access request of the access request of the access static page and access dynamic page is distributed to corresponding static Web page server and active server page; The suffix of described URL address can be html or jsp etc.;

In this step, because virtual from the traditional sound page separation based on cloud computing platform is different, it is advantageous that the flexible dynamic assignment of empty machine resource, iff statically static page being separated with dynamic page, will inevitably bring certain potential safety hazard to web page access, because always have one or several fixing web page servers long-term be exposed to outside, this access for cloud storage is disadvantageous, because relate to the information material of various aspects in cloud storage, once be attacked, consequence is hardly imaginable, based on the consideration of safety and cloud computing feature, on original sound separation mechanism, this step is also specifically: set in advance multiple virtual page servers, each virtual page server is all equipped with active server page and static Web page server, resolve the access request from client terminal web page browser, according to the suffix of the URL address of the page of described access request access, determine the page type of access request access, all virtual page servers are adopted to the conduct interviews distribution of the access request of static page and the access request of access dynamic page of polling mechanisms, that is:

By virtualization software, several virtual page servers are set, and be that each virtual page server is set numbering, for convenience of description, suppose that the empty machine web page server number of distributing is n platform, n is even number, the numbering of each virtual page server is respectively 1,2 ..., n, and the performance of each virtual page server is suitable, be all equipped with active server page and static Web page server; Described virtualization software is as the iwd software of Vmware or IBM;

Page storage place equipment comprises two independently physical servers, and static Web page page stores, in a physical server, is made as S here 1, dynamic web page page stores, in another physical server, is made as S here 2;

At moment t 1, be numbered 1,3 ..., the virtual page server of n-1 is connected to S 1number physical server, is numbered 2,4. ..., the virtual page server of n is connected to S 2number physical server, and do respectively load balancing, the page type of the physical server storage that each virtual page server connects according to self, determines self sound pattern, as being connected to S 1when number physical server, only open static Web page page server, and close dynamic web page page server, vice versa;

Resolve the access request from client terminal web page browser, according to the page type of access request access, the access request of the access static page is distributed to the virtual page server as static Web page server, the access request of access dynamic page is distributed to the virtual page server as active server page;

After one-period δ t, the mode that all virtual page servers are connected to physical server is carried out a next round and is turned, the dynamic switching of the action quiet mode of going forward side by side, as: be numbered the virtual page server of x, x is 1,2 ..., n-1, at t 1in+δ t the moment, numbering becomes x+1, and the physical server being connected to carries out respective change, switches sound pattern according to the page type of the physical server storage being connected to.

In this way can original based on moving static page separation mechanism web page access mechanism on, strengthened fail safe and the flexibility of system network access to web page.

In this step, the instantiation of described polling mechanism was as cycle 1 o'clock, as shown in Figure 2, in cloud storage system, sound separates agency the Http request from client terminal web page browser is moved to static page separation, the Http request of the access static page is distributed to No. 1 virtual page server and No. 9 virtual page servers, the Http request of access dynamic page is distributed to No. 7 virtual page servers and No. 8 virtual page servers, all the other virtual page servers are awaited orders according to specific needs, as in step below according to visit capacity dynamic capacity-expanding etc.; In the time arriving the 2nd cycle, as shown in Figure 3, according to the rotary press system between virtual page server, if all virtual page servers are to one of reach, the Http request of the access static page is distributed to No. 8 virtual page servers and No. 9 virtual page servers, the Http request of access dynamic page is distributed to No. 6 virtual page servers and No. 7 virtual page servers, and the virtual page server that is exposed to sound separation agency converts.

The universal model of rotary press system as shown in Figure 4, the dynamic web page page (jsp, php, the files such as asp) and the static Web page page (html, the files such as htm) fixed storage is in different physical servers, at cycle n, active server page is deployed in respectively 2, 3, on No. 4 virtual page servers, static Web page server is deployed in respectively 5, on No. 6 virtual page servers, in the time of next cycle n+1, the virtual page server that separates proxy access for sound remains 3 dynamically, 2 static state, but empty machine web page server does a next round transformation and changes, make virtual page server be exposed to sound and separate the network address change of acting on behalf of, thereby reach the effect that increases fail safe, in Fig. 4, the round robin adopting is, identification number is the mode of cyclic shift forward.

Here, can be according to active user visit capacity, cloud storage system utilizes virtualization software dynamically virtual page server number to be distributed, and this not only turns the flexibility of configuration from having strengthened empty wheel, can effectively improve the service efficiency of entire system simultaneously; Describedly dynamically virtual page server number is assigned as: expand or delete based on the cluster structured number to virtual page server;

Concrete, as shown in Figure 5, cloud storage system is divided into virtual page cluster of server by virtual page server according to geographical position, the N having in the region of relatively concentrating by geographical position virtual page server is divided into a virtual page cluster of server, and the shared computational resource of the static Web page server in each virtual page cluster of server on each virtual page server and active server page is made as respectively m iand n i, i=1,2 ..., N, is limited to α on the computational load of each virtual page server, expands or delete comprising the steps: based on the cluster structured number to virtual page server

(1) cloud storage system arranges resource pool, in described resource pool, there are multiple virtual page servers to be applied for, for each virtual page cluster of server, be deployed in flowing of access control software on each virtual page server and carry out traffic scanning statistics every the time of Δ t, occur following four kinds of situations:

(a) load of each virtual page server is all greater than load upper limit α, has for all i

m i+n i≥α

(b) load of part virtual page server is greater than load upper limit α, part is less than α, and can meet loading demand by current scheduling of resource, and establishing k is the virtual page server set that exceedes the load upper limit, j is the virtual page server set that does not exceed the load upper limit,

Nα-∑(m k+n k)≥∑(m j+n j)

(c) load of part virtual page server is greater than load upper limit α, and part is less than α, but current virtual page server resource cannot meet loading demand, that is:

Nα-∑(m k+n k)<∑(m j+n j)

(d) all do not exceed load upper limit α, have for all i

m i+n i<α

(2) for (a) situation, each virtual page server calculates respectively own scarce resource and unifies application to resource pool, cloud storage system distributes corresponding new virtual page server according to lacked resource summation from resource pool, described being assigned as: calculate scarce resource summation the flow of adding up access static web page server and active server page be respectively β and γ, the scarce resource summation Λ of described calculating is:

Λ=2*(∑(m i+n i)-Nα)

Disposable distribution meet the virtual page server of scarce resource summation Λ, and carry out resource division according to the flow rate ratio of static Web page server and active server page, from lacked resource summation Λ, mark off the resource Λ of static Web page server staticresource Λ with active server page dynamically:

Λ static=(β/(β+γ)) Λ

Λ dynamically=(γ/(β+γ)) Λ

For (a) situation, specifically as shown in Figure 6, four scarce resources of existing virtual page server, are born by newly assigned virtual page server.

For (b) situation, each virtual page server calculates self scarce resource A k,

A k=α-m k-n k

By flow control software, flow is shared equally:

A(α-m j-n j)/(N jα-∑(m j+n j))

For (b) situation, specifically as shown in Figure 7, the flow that exceeds load upper limit α is apportioned to the virtual page server that is less than load upper limit α to load.

For (c) situation, owing to cannot meet the distribution of system resource according to the method for situation (b), therefore first need according to circumstances (b) that resource is shared on the virtual page server of each resource abundance, then the resource not satisfying the demands according to residue is carried out the application of new virtual page server according to situation (a).

For (d) situation, without carrying out any operation.

When the resource utilization of virtual page server is during lower than a certain thresholding, can carry out resource recovery.

If in a certain virtual page cluster of server, can not be when expanding or delete that virtual page server meets traffic demand, be that resource pool in a certain virtual page cluster of server is used up, need to report to upper level resource pool, the resources regulation method of upper level resource pool is still carried out resource allocation according to the mode of above-mentioned (a), (b), (c) three kinds of situations, and just above-mentioned (a), (b), (c) three kinds of situations become situation about representing between each virtual page cluster of server from the situation in virtual page cluster of server that represents.

For choosing of geographical position, can select according to the distance of data center machine room, each machine room as one independently clustering architecture carry out pooling of resources management and control.

Step 103: web page server is mapped to physical server by the access request receiving and carries out page documents processing; Described page documents processing can be reading and writing data and/or data encryption and/or data backup and/or data compression and/or Data dissemination etc.
