Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes a block chain based cloud service management method and system provided by an embodiment of the present invention with reference to fig. 1 to 9.
Fig. 1 is a schematic flowchart of a block chain-based cloud service management method provided in the present invention, as shown in fig. 1, including, but not limited to, the following steps:
step S1: receiving service registration requests of a plurality of cloud service providers, wherein each service registration request at least comprises service related information;
step S2: extracting the service related information by using an intelligent contract so as to add the service registration request of each cloud server into a blockchain;
step S3: receiving a service request of at least one cloud user;
step S4: matching a target service registration request from the blockchain according to the service request by using the intelligent contract to establish matching between each cloud user and the target cloud server;
the target cloud server is a cloud server corresponding to the target service registration request.
In consideration of the defects that the existing centralized cloud service management method for realizing cloud service management by means of cloud agents has higher unreliable selection risk and high time consumption of selection caused by a large number of similar cloud services, the cloud service management method based on the block chain provided by the invention adopts a decentralized block chain and utilizes the advantages of the block chain to design a distributed cloud service management mechanism based on the block chain. The implementation steps of the whole block chain-based cloud service management method can include, but are not limited to, four parts of cloud service and cloud user registration, service request, service matching and service transaction, service provision and service evaluation. The method realizes automatic retrieval, search, provision, use and release of all required cloud computing resources in a distributed cloud service system constructed based on a block chain and an intelligent contract technology, and completes reliable transaction between a cloud user and a cloud service provider.
Specifically, in step S1, the cloud service management system based on the block chain sequentially collects the service registration requests of all cloud servers
The distributed cloud service management system based on the block chain mainly comprises two major application entities, namely a cloud service provider (also called cloud server, CSP) and a cloud service consumer (also called cloud user). The cloud server can be divided into three types of different resource providers and corresponds to two types of cloud block chain nodes.
The nodes corresponding to the three types of service parties with different resources in the block chain are respectively a personal service provider, a cloud service agency and an enterprise-level cloud service provider, which are distributed at different geographic positions to form a cloud block chain network based on a block chain technology.
On the other hand, the cloud server is respectively a block chain light node and a block chain standard node according to two types of cloud block chain nodes corresponding to the self-capability. The block chain light node only stores part of the block data (for example, the relevant information of the service provider node in the close range) of interest of the block chain because of limited resources, and the standard node is a block chain network basic node and stores the whole network complete block chain data. Generally, the personal service provider and the cloud service agency are configured as blockchain light nodes due to their limited resources, while the enterprise-level cloud service provider is configured as blockchain standard nodes.
In step S1, a service registration request of each cloud server added to the block chain is acquired first. And each registration request sends a service registration request to a distributed cloud service network system. The service registration request must include service-related information to specify the service type, the set of service quality parameters, the amount of service resources, the price of the service unit resources, and the like that can be provided.
In step S2, the cloud service network system extracts the service-related information carried by each service registration request by using the intelligent contract in the blockchain, and publishes the information to the blockchain in the form of transaction, so that the service-related information corresponding to the service registration requests published by all cloud servers is published in the whole blockchain.
In step S3, when the cloud service network system receives the service requests of one or more cloud users at a certain time point, the service requirement information related to the service request issued by each cloud user is correspondingly read.
In step S4, after the service demand information of each cloud user is acquired, all the service demand information is matched with all the service related information related to service registration in the block chain by using an intelligent contract, so as to realize the optimal service matching between the cloud server and the cloud user.
Fig. 2 is a second schematic flowchart of the block chain based cloud service management method provided by the present invention, and as shown in fig. 2, on the basis of the foregoing embodiment, the present invention provides a block chain based cloud service management method, including but not limited to the following steps:
At Step 2, an input command (IN) is received.
Step6, the service evaluation Step mainly comprises the following steps: and calling an intelligent contract to update the service credit, updating the service evaluation, storing the service evaluation to a block chain, and turning to Step 7.
And Step 8, ending.
The invention provides a block chain-based cloud service management method, in particular to a block chain technology-based distributed cloud service method constructed based on a block chain and an intelligent contract technology, which can register social idle resources into distributed cloud services and improve the utilization efficiency of the social idle resources; meanwhile, a better service selection platform is provided for the user, and the user can select the cloud service which meets the self requirement; and the cloud service transaction is recorded by using the block chain, so that the transaction certificate is guaranteed not to be tampered, and the optimized bidirectional selection of the user and the service provider can be better met.
Based on the content of the foregoing embodiment, as an optional embodiment, the matching, according to the service request, a target service registration request from the block chain by using the intelligent contract specifically includes:
and matching the service demand information of the service request with the service related information of each service registration request based on a service matching algorithm of an intelligent contract technology to determine a target service registration request corresponding to the service request.
Fig. 3 is a schematic diagram of a service request in the cloud service management method based on a block chain provided in the present invention, and as shown in fig. 3, a cloud server sends a service registration request to a distributed cloud service network, where each service registration request includes corresponding service-related information, and mainly includes: service-related information such as service type, service quality parameter set, service resource amount, service unit resource price, etc. The intelligent contract in the blockchain will extract this information and write it into the blockchain, waiting for a service request.
The cloud user can initiate service requests to a distributed cloud service network based on a block chain, wherein each service request contains service requirement information corresponding to the service request, and the service requests comprise: various service attribute requirements (including functional attributes and non-functional attributes), resource quantity requirements and the like for the target service. The service request will trigger a service matching algorithm based on intelligent contract technology. The service matching algorithm respectively considers factors such as the maximum capital expenditure borne by the service requester (each cloud user) and the optimal service quality of the service provider (each cloud server) to complete the optimal service matching.
According to the cloud service management method based on the block chain, the intelligent contract technology of the block chain is utilized, the matching processing of the service request is realized, a distributed cloud service management mechanism based on the block chain is designed, and the safe p2p resource transaction is guaranteed. The distributed cloud service system constructed based on the block chain technology and the intelligent contract technology can realize automatic retrieval, search, provision, use and release of all required cloud computing resources, and complete reliable transactions.
Based on the content of the foregoing embodiment, as an optional embodiment, the matching, by the service matching algorithm based on the intelligent contract technology, the service requirement information of the service request and the service related information of each service registration request are matched, including:
under a single-user service matching scene, determining one of service related information of all the service registration requests with the highest matching degree with service demand information of the service request of the cloud user as a matching object;
under a multi-user service matching scene, a target service registration request corresponding to a service request of each cloud user is determined based on maximization of a total matching rate and a total matching quality of the cloud users and minimization of a total matching price as matching targets.
Further, in the process of realizing the matching operation of the service request by the service matching algorithm based on the intelligent contract technology, the cloud block chain network can realize the service matching algorithm based on the intelligent contract so as to realize comprehensive matching by considering the service related information of the service provider according to the service demand information of the user.
Specifically, under the single-user service matching scene, the service matching is completed by maximizing the service demand matching amount of the user, and meanwhile, the resource pricing is realized.
Since only one cloud user participates in matching, the matching amount of the service demand information of the cloud user and the service related information of any service registration request is maximized to serve as a matching target, so that the cloud user is matched with an optimal cloud server.
Fig. 4 is a schematic diagram of service matching and transaction records in the cloud service management method based on the block chain, and as shown in fig. 4, in the face of a more common multi-user simultaneous service matching scenario, the social welfare is maximized, and service matching is achieved with the service quality and the service price as factors.
For example, the goal of maximizing social welfare may be understood as: if 100 cloud users send service requests to participate in optimal matching, the social welfare maximization refers to the maximum quantity which can meet the requirements of the cloud users to the maximum extent. Such as: if the first matching result is a matching requirement that can simultaneously satisfy 80 cloud users, and the second matching result is a matching requirement that can simultaneously satisfy 98 cloud users, it can be considered that the second matching result is a matching result that aims at maximizing social welfare.
The quality of service may include attribute parameters such as jitter rate, interruption rate, and response time of the service. The quality of service is greater the smaller the jitter rate, the lower the outage rate, and the shorter the response time. And the total matching quality can be understood as the comprehensive quality (such as an average value or an accumulated value) of the matching qualities corresponding to all cloud users.
Wherein the matching price is a difference between a willingness price of the service request for each cloud user and a service price of each corresponding cloud server. Generally, the lower the matching price, the higher the matching degree. And the average matching price can be understood as a comprehensive price (such as an average value or an accumulated value) of the matching prices corresponding to all the cloud users.
Furthermore, the service matching algorithm based on the intelligent contract technology can also realize intelligent matching operation according to the comprehensive reputation of each cloud server and the standardized service quality of each cloud server, and the like, which are used as matching parameters, and the invention is not particularly limited.
According to the cloud service management method based on the block chain, the requirements of the cloud user and the cloud service provider are automatically matched by using the service matching algorithm of the intelligent contract technology, the service management mechanism provides a better service selection platform for the user, and the user can select the cloud service which meets the requirements of the user; and recording cloud service transactions by using a block chain, and ensuring that transaction certificates cannot be tampered. The distributed cloud service based on the block chain can better meet the optimized bidirectional selection of users and service providers.

registering each cloud server based on a distributed cloud service network of a block chain, and distributing a unique service account for each cloud server;
before receiving the service request of at least one cloud user, the method further comprises the following steps:
and registering each cloud user based on the distributed cloud service network of the block chain, wherein each cloud user is not allocated with a unique user account.
The distributed cloud service network based on the block chain allows access to various cloud service persons, the registered cloud service persons are assigned with a unique service account, and each cloud service person can use the service account to publish service information of the cloud service person to the block chain. As a client node in the blockchain network, each cloud user completes registration of a user account before requesting a service to obtain a service account of a target cloud server.

The registration of the cloud server is relatively high in requirement, and includes: the cloud server uploads a service registration request to a cloud service management network; after receiving the service registration request, the cloud service management network completes registration and publication of corresponding information on a block chain and sends the generated account and the account private key to the cloud server; then, the cloud server can realize instant publishing of the service information based on the account, and can receive corresponding service registration corresponding information and the like at any time.
According to the cloud service management method based on the block chain, the identity, the release information and the like of each cloud user and each cloud server are managed in a unified mode through authentication and registration, and the safety and the reliability of transactions are effectively guaranteed.
Based on the content of the foregoing embodiment, as an optional embodiment, the service related information at least includes: service type, service quality parameter set, service resource amount and service unit resource price; the service requirement information at least comprises: service attribute demand, resource quantity demand, demand unit resource price.

The set of quality of service parameters may include: safety; availability; reliability; responsiveness: satisfaction and assurances, each of which contains several specific indexes. Based on the basic index evaluation method, the service quality parameter set is defined as A ═ Aqual,Aquan} of whichIn Aqual＝{l1,...,lkIs k qualitative attributes, Aquan＝{n1,...,nmIs m quantitative attributes.
