Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of method of management resource information, and the method comprises:
101, server receives and preserves the resource information of cloud application, and resource information comprises the configuration information of each resources of virtual machine that the cloud application takies.
The present embodiment does not limit the type of cloud application, i.e. cloud application can be for operating in arbitrarily the application in the cloud platform, as SMS service center (Short Message Service Center, SMSC), communication charge center etc.Each resources of virtual machine that the cloud application takies can be the resources of virtual machine of cloud application from applying for the flexible resource pond.
Wherein, the configuration information of resources of virtual machine comprises at least a in account, agreement, port numbers or the IP address of virtual machine.
The cloud application can be issued the resource information of self on server.Server is preserved this resource information after receiving the resource information of cloud application issue, so that circumferential component is subscribed to the resource information of this cloud application on server.
Concrete, server can be preserved the resource information of cloud application according to tree data structure, tree data structure comprises the cloud application node, under the cloud application node, comprise each virtual machine node that cloud application takies, under each virtual machine node, comprise respectively at least a in account node, protocol node, port numbers node or IP address node.As shown in Figure 2, at tree data structure, comprise a cloud application.Under this cloud application, include two virtual machine node, i.e. this cloud application has taken two resources of virtual machine, is respectively virtual machine 1 and virtual machine 2.Account node, protocol node, port numbers node and the IP address node that under virtual machine node, can also comprise this virtual machine.Wherein, under the account node, preserve account title and the password of this virtual machine.Under protocol node, preserve the concrete agreement of this virtual machine, comprise short message point-to-point (Short Message Point to Point, SMPP) as the protocol node in virtual machine 1; Protocol node in virtual machine 2 comprises infoX-WebSMS point-to-point (Enterprise Message Point to Point, EMPP).
102, when the discovering server cloud was applied the resources of virtual machine generation change taken, server obtained the modification information of the resources of virtual machine that change occurs.
The modification information that server obtains the resources of virtual machine that change occurs is specially server and cloud is applied in to resources of virtual machine the resource information sent after changing occurs with the resource information of preservation, compares, using that compare and the modification information of the inconsistent part of resource information preservation as resources of virtual machine.
Wherein, the resources of virtual machine that takies of discovering server cloud application process that change occurs specifically can comprise: server receives cloud and is applied in resources of virtual machine the resource information sent after changing occurs; Server finds that according to this resource information change has occurred the resources of virtual machine that the cloud application takies.Concrete, when change occurred the resources of virtual machine of cloud application, the cloud application can send to server by the resource information occurred after changing.Therefore, be applied in case server receives cloud the resource information that the resources of virtual machine generation sends after changing, server determines that change has occurred the resources of virtual machine that this cloud application takies.Server is when receiving the resource information of cloud application transmission, can check that it is that cloud is applied in the initialization resource information that the resource information sent after changing or cloud application occur resources of virtual machine that the resource information of whether preserving this cloud application is identified the resource information received, if preserved the resource information of this cloud application, the resource information received is that cloud is applied in the resource information that the resources of virtual machine generation sends after changing.
103, server obtains the subscription range of each feed of having subscribed to the cloud application, the resources of virtual machine of change occurs whether in the subscription range of each feed in judgement, the modification information of the resources of virtual machine in subscription range is sent to corresponding feed, modification information is for instructing feed to carry out the topology change, in the virtual machine that is diverted to the cloud application that business is correct.
Wherein, feed refers to the application of the resource information of having subscribed to the cloud application.Feed can be that part is subscribed to or all subscribed to the subscription of the resource information of cloud application.Therefore, after the resource information of cloud application changes, server need to judge that the resources of virtual machine that change occurs is whether in the subscription range of each feed, if change has occurred the resource information in the feed subscription scope, server sends to this feed by the modification information of the resources of virtual machine in this feed subscription scope.
Wherein, topology change refer to in feed and the annexation between the virtual machine of cloud application change.Such as, when modification information was the resources of virtual machine information increased newly, feed can be increased to according to the information of newly-increased resources of virtual machine the connection of newly-increased resources of virtual machine.
104, the resource information of the cloud application that server update is preserved.
Concrete, server will obtain the modification information of resources of virtual machine of generation change be kept in corresponding tree data structure, to reach the purpose of the resource information of upgrading the cloud application, and guarantee to store in server apply up-to-date resource information for cloud.
The embodiment of the present invention is by the resource information of issue cloud application in server, and the resource information change of cloud application is notified dynamically to the circumferential component that subscribing relationship is arranged, make circumferential component know in time the flexible situation of the shared resources of virtual machine of this cloud application, realized the self adaptation of circumferential component to cloud application dynamic retractility function thereby carry out automatically the topology change.
In order to improve the fail safe of system, server can only be accepted issue source and in server, issue resource information.Therefore, in another embodiment of the present invention, can further include before step 101: the cloud application applies to become issue source to server.
Wherein, cloud application applies to become the issue source specific implementation to server and can be: the cloud application sends the issue source application request that applies to become issue source to server.Wherein, issue source application request comprises the sign of this cloud application, and server is issue source according to issue source application request by this cloud application records.
Optionally, in issue source application request, except the sign that comprises the cloud application, can further include the password of cloud application, the IP address of cloud application.Server carries out authentication to the content of this issue source application request, judges whether the content in this issue source application request is correct.According to authenticating result, determine to the cloud application and send issue source application response message.When the content of issue source application request was correct, server was issue source by this cloud application records, and was the application success message to the issue source application response message that the cloud application sends, and the cloud application becomes issue source.Otherwise when the content of issue source application request was incorrect, server was the application failed message to the issue source application response message that the cloud application sends, the cloud application can not become issue source.
What deserves to be explained is, above-mentioned issue source application request can possess registration and apply for this two kinds of functions, or does not possess registration, only possesses the function of application.When this issue source application request possessed the function of registration and application, the cloud application was after server sends issue source application request, and the cloud application can become issue source.When this issue source application request do not possess registration, while only possessing the function of application, before cloud application sends issue source application request to server, optional, to server, send registration request.As shown in Figure 3, the cloud application applies to become the method for issue source to server, and the method comprises:
301, the cloud application sends registration request to server.
Concrete, registration request is applied on server and registers for cloud.
Wherein, registration request comprises the log-on message of cloud application, as, the password that the sign of cloud application, cloud application arrange and the IP address of cloud application.
302-303, the log-on message of this cloud application of server record, and send registration reply message to this cloud application.
After server receives registration request, can carry out legitimate verification to sign or the IP address of cloud application, after being verified, send and show the response message succeeded in registration to this cloud application, if checking is not passed through, return to the response message that shows registration failure.For example, when this cloud application was succeeded in registration, the conditional code in registration reply message was 0, i.e. registration reply message is the message that succeeds in registration, and then continues to carry out 304; When this cloud application registration failure, the conditional code in registration reply message is 1, i.e. registration reply message is registration failure message.
304, after registration reply message that this cloud application reception server sends was for the message that succeeds in registration, this cloud application was to server transmission issue source application request.
Issue source application request can comprise the sign of cloud application, the IP address of the password of cloud application, cloud application.It should be noted that, in the embodiment of the present invention, issue source is the application of issue resource information.
305, this cloud of server record is applied as issue source.
Server receives the issue source application request that the cloud application sends, according to the information of carrying in issue source application request, cloud is applied and carried out authentication, as, whether the cloud application identities that comparison issue source application request is carried mates with the cloud application identities in password and log-on message and password, if coupling, authentication success, server is issue source by this cloud application records.
It should be noted that, this cloud application in the present embodiment sends respectively registration request and issue source application request to server, and this mode can be applied to after this cloud is applied in and succeeds in registration, send issue source application request according to actual ruuning situation.
Certainly, in another embodiment of the present invention, the cloud application also can only send issue source application request, and without sending registration request, server, when receiving issue source application request, completes the registration of cloud application and is registered as issue source.
Issue source can be regarded as cloud and is applied in an identity in server.But in actual conditions, the cloud application can have a plurality of identity in server, such as, the cloud application can be both issue source, can be also the feed of subscribing to the resource information of other cloud application.
Cloud can be published to the resource information of self in server after being applied in and becoming issue source.When other application needs to subscribe to the resource information of this cloud application, the resource information that can apply from obtaining this cloud server, and subscribe to according to the resource information of obtaining.Wherein, server can send to feed with the form of tree data structure by the resource information of the cloud of preservation application.
Concrete, the subscription procedure of the resource information of cloud application specifically can comprise: server sends to feed by the resource information of the cloud of preservation application; Server receives the subscribe request that feed sends, and this subscribe request comprises the sign of this feed, and this feed is for the subscription range of the resource information of cloud application; The subscription range of this feed of server record.Subscription range can be described with the path of resource information in tree data structure of subscribing to.
It should be noted that, issue source is similar with applying to become, and feed also can be registered in server.Application can be registered by the feed application request sent to server, and now, this feed application request can possess registration and apply for this two kinds of functions.Similar with issue source application request, feed application request also can not possess registration, only possess the function of application.When this feed application request possessed the function of registration and application, the cloud application was after server sends feed application request, and the cloud application can become feed.When this feed application request do not possess registration, while only possessing the function of application, before cloud application sends feed application request to server, optional, to server, send registration request.As shown in Figure 4, application applies to become the method for feed to server, and the method comprises:
401, application sends registration request to server.
Registration request comprises the log-on message of application, as, the password that the sign of application, application arrange and the IP address of application.
Being understandable that, although the application in this step can be the cloud application, can be also the application of other non-cloud, and the processing procedure of the processing procedure of step 401-403 and step 301-303 is similar, repeats no more here.
Its 402-403, the log-on message that server record should be applied, send registration reply message to this application.
The description of registration reply message can be with reference to 303 in figure 3.
404, after registration reply message that this application reception server sends was for the message that succeeds in registration, this cloud application was to server transmission feed application request.
In this step, feed application request comprises the sign of application, the IP address of the password of application or application.
405, this is applied as feed server record.
Feed is an identity of this application, and certainly, this application also can apply to become issue source.
It should be noted that, this application in the present embodiment sends respectively registration request and feed application request to server, and this mode can be applied to after this is applied in and succeeds in registration, send feed application request according to actual ruuning situation.
Certainly, in another embodiment of the present invention, this application also can only send feed application request, and without sending registration request, server, when receiving feed application request, completes the registration of cloud application and is registered as feed.
It should be noted that, apply to become again feed if same application should apply to become issue source, can only initiate one time so registration request.This application can first send registration request to server, then needs actual demand, sends issue source application request and feed application request to server.This cloud application has two identity like this: issue source and feed.Perhaps, this cloud application sends issue source application request and feed application request to server.Certainly, after the cloud application becomes issue source, can send resource information to server.And, after cloud application becomes feed, also need to server to send subscribe request, so that server records the subscription range of feed according to this subscribe request.About the description of subscribe request, please refer in Fig. 1 103 explanation.At this, do not repeat one by one.
As shown in Figure 5, being described in detail as follows of change occurs in the resource information of cloud application:
501, the cloud application sends business information to the cloud management platform.
Cloud Host Administration platform is organized and is divided and detect for the various resources to application.Business information comprises the information such as central processing unit (Central Processing Unit, CPU) occupancy, memory usage, storage occupancy, network I/O (Input/Output, I/O) occupancy, storage read-write I/O occupancy.
It should be noted that, the cloud management platform can be an independently equipment, also can belong to same equipment with server.When cloud management platform and server were an equipment, cloud management platform and server were respectively two administrative units of this equipment difference in functionality.
502, the cloud management platform is according to this business information, and whether the resource information that detects the cloud application needs change.
When above-mentioned business information occupancy reaches more than 90%, and while surpassing the scheduled time, the cloud management platform determines that the cloud application needs dilatation.Wherein, the present embodiment did not limit the scheduled time, such as, the scheduled time can be 10min.
In addition, whether the cloud management platform resource information that often will detect at regular intervals cloud application changes.For example, when the cloud management platform detects the IP bandwidth of IP address of node 1 correspondence in cloud application when inadequate, the cloud management platform changes the IP address of node 1 correspondence.When the cloud management platform determines that the cloud application needs the resource information of dilatation or cloud application to change, continue to carry out 503; When the cloud management platform only determines that the resource information of cloud application changes, continue to carry out 505.
503, when the cloud application needed the dilatation resource, the cloud management platform sent capacity-enlarging information to the flexible resource pond.
For example, former two virtual machines (virtual machine 1 and virtual machine 2) that occupy of cloud application, dilatation now a virtual machine (virtual machine 3), capacity-enlarging information comprises newly-increased virtual machine 3, and the configuration information of virtual machine 3 correspondences.
504, the flexible resource pond, according to this capacity-enlarging information, sends new resources information in the cloud application;
505, the cloud application receives modification information.
Cloud is applied in reception modification information (new resources information and/or change resource information) and afterwards, the resource information of preservation is upgraded.
Method below by the concrete management resource the information for example embodiment of the present invention provided is elaborated, and as shown in Figure 6, the method comprises:
601, the cloud application connects with server.
When the cloud application connected with server, the cloud application sent connection request to server.Wherein, this connection request is for setting up being connected between cloud application and server.After server receives connection request, send and connect response message to the cloud application.This connection response message is used to indicate connection request, and whether serviced device is successfully accepted.For example, when cloud application and server connect when successful, the conditional code connected in response message is 0, then continues to carry out 602; When the cloud application connected failure with server, the conditional code connected in response message was 1.
602, the cloud application applies to become issue source to server, and this cloud of server record is applied as issue source.
About cloud, applying the detailed description that becomes issue source can be with reference to the explanation of each step in figure 3.
603, after the cloud application became issue source, the cloud application sent initialized resource information to server.
Illustrate, the initialization resource information comprises two virtual machines, be respectively virtual machine 1 and virtual machine 2, wherein the account name of virtual machine 1 is called application A1, corresponding password is 123456, the protocol name of virtual machine 1 is SMPP, and the IP address of virtual machine 1 is 1.1.1.1, and the port numbers of virtual machine 1 is 01; The account name of virtual machine 2 is called application A2, and corresponding password is 456123, and the protocol name of virtual machine 2 is EMPP, and the IP address of virtual machine 2 is 2.2.2.2, and the port numbers of virtual machine 2 is 02.
604, the resource information of server cloud application is carried out index and storage according to tree data structure.
Server carries out explaining of 101 pairs of tree data structures in schematic diagram that the description of index and storage can show with reference to figure 2 and Fig. 1 by resource information according to tree data structure.
605, server sends to the resource information of the cloud of preservation application the feed of record.
Optionally, the resource information of the cloud application of the preservation that sends to feed of server can be the tree form data structure of the cloud application of preserving.
After the application success application was feed, server sent to feed by the tree data structure of each issue source of current preservation.For example, if when this application becomes feed, in server, preserve the tree data structure of the initialization resource information of the cloud application that is, server sends the tree data structure of initialized resource information to feed.When if this application becomes feed, the tree data structure of the resource information after changing of the cloud application of preserving in server, server sends tree data structure after changing to feed.
606, feed sends subscribe request to server.
Subscribe request comprises the sign of feed, and feed is for the subscription range of the resource information of cloud application.For example, feed is application B and application C.Wherein, application B comprises that to the subscribe request that server sends subscription range is whole resource informations of cloud application A, and the subscription range that the registration request that application C sends to server comprises is the IP address node of virtual machine 1 in cloud application A.Wherein, subscription range can be meaned by the path of resource information in tree form data structure of subscribing to.For example, application B is " application A/ " to the subscription range in the subscribe request of server transmission; Application C is " application A/ node 1/IP address " to the subscription range in the subscribe request of server transmission.
607-608, the subscription information of server record feed, send and subscribe to feedback message to feed.
Wherein, the subscription information of feed comprises the sign of cloud application of subscription and the subscription range corresponding with the sign of this cloud application.
Subscribe to feedback message for determining whether feed subscribes to successfully.
Concrete, feed judges whether to subscribe to successfully according to the conditional code in this subscription feedback message.For example, when the feed subscription success, the conditional code of subscribing in feedback message is 0, then can continue to carry out 611; When the feed subscription failure, the conditional code of subscribing in feedback message is 1.
609, when change occurred the resource information in the cloud application, the cloud application sent resource information after changing to server.
