Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The blockchain-based cloud service management method and system provided by the embodiments of the present invention are described below with reference to FIGS. 1-9 .

Fig. 1 is one of the flow diagrams of the blockchain-based cloud service management method provided by the present invention, as shown in Fig. 1, including but not limited to the following steps:

Step S1: receiving service registration requests from multiple cloud service providers, each of which includes at least service-related information;

Step S2: using the smart contract to extract the service-related information, so as to add the service registration request of each cloud service provider to the blockchain;

Step S3: receiving a service request from at least one cloud user;

Step S4: According to the service request, use the smart contract to match the target service registration request from the blockchain to establish a match between each cloud user and the target cloud service provider;

The target cloud service provider is the cloud service provider corresponding to the target service registration request.

Considering that the existing centralized cloud service management method that relies on cloud agents to realize cloud service management has defects such as high risk of unreliable selection and high time-consuming selection caused by a large number of similar cloud services, the present invention provides The blockchain-based cloud service management method adopts the decentralized blockchain and utilizes the advantages of the blockchain to design a distributed cloud service management mechanism based on the blockchain. The implementation steps of the entire blockchain-based cloud service management method may include, but are not limited to, four parts: cloud service and cloud user registration, service request, service matching, service transaction, service provision, and service evaluation. In the distributed cloud service system based on blockchain and smart contract technology, all cloud computing resources required are automatically retrieved, searched, provided, used, and released, and reliable transactions between cloud users and cloud service providers are completed.

Specifically, in step S1, the blockchain-based cloud service management system first sequentially collects service registration requests from all cloud service providers

The blockchain-based distributed cloud service management system provided by the present invention mainly includes two types of applications: cloud service provider (also known as cloud service provider, CSP) and cloud service consumer (also known as cloud user). entity. Among them, cloud service providers can be divided into three types of different resource providers and correspond to two types of cloud blockchain nodes.

Among them, the nodes corresponding to the service providers of the three types of different resources in the blockchain are individual service providers, cloud service agencies, and enterprise-level cloud service providers. They are distributed in different geographical locations and based on blockchain technology Constitute a cloud blockchain network.

On the other hand, cloud service providers correspond to two types of cloud blockchain nodes according to their own capabilities, namely blockchain light nodes and blockchain standard nodes. Among them, due to their limited resources, the light nodes of the blockchain only store some of the block data that they are interested in in the blockchain (for example, information about service provider nodes within close range), while the standard nodes are block The basic node of the chain network saves the complete blockchain data of the entire network. Generally speaking, personal service providers and cloud service agencies are configured as blockchain light nodes due to their limited resources, while enterprise-level cloud service providers are configured as blockchain standard nodes.

Wherein, each of the registration requests sends a service registration request to the distributed cloud service network system respectively. Among them, the service registration request must include service-related information to describe the type of service that can be provided, the set of service quality parameters, the amount of service resources, and the price of service unit resources.

In step S2, the cloud service network system uses the smart contract in the blockchain to extract the service-related information carried by each service registration request, and publishes the information to the blockchain in the form of transactions, so that the entire The service-related information corresponding to the service registration requests issued by all cloud service providers is published publicly in the blockchain.

In step S3, when the cloud service network system receives service requests from one or more cloud users at a certain point in time, it correspondingly reads the service requirement information related to the service requests issued by each cloud user.

In step S4, after obtaining the service demand information of each cloud user, use the smart contract to match all the service demand information with the service-related information related to all service registrations in the blockchain, so as to realize cloud service providers and Optimal service matching among cloud users.

Identify the type of input instruction, so as to realize the jump of different steps according to the different instruction types, including: transfer to the step of registration and service release (i.e. go to step 4); transfer to the step of service request (i.e. Go to step 5) or go to the step of service evaluation (ie go to step 6).

Step 4, in the steps of registration and service publishing, mainly includes: it can be judged whether the cloud service provider has a legal service account; if so, analyze whether the command of the cloud service provider is a service registration command; if so, complete the registration of the service request, and Extract the service attributes and service-related information of the service registration request, publish them to the blockchain in the form of transactions, and then go to step 7; if the cloud service provider’s instruction is not a service registration instruction, go to step 7 directly. If the cloud service provider does not have a legal service account, account registration is performed for the cloud service provider.

Step 5, the steps of service request, mainly include: calling the smart contract to execute the service matching algorithm, the user cooperates with the service provider off-chain, signs a Service Level Agreement (Service Level Agreement, SLA), stores the SLA in the blockchain, and completes the service Transaction, update service status, go to step6. business

Step 6, the steps of service evaluation, mainly includes: call smart contract to update service reputation, update service evaluation, store service evaluation to blockchain, and turn to Step 7.

Step 7. Determine whether the system is operating normally. If it is operating normally, enter step 3 again to perform iterative monitoring and processing steps; if it is not normal, proceed to step 3 to step 8.

Step 8, end.

It can better satisfy the optimal two-way choice of users and service providers.

Based on the content of the above-mentioned embodiment, as an optional embodiment, using the smart contract to match the target service registration request from the blockchain according to the service request specifically includes:

The service matching algorithm based on smart contract technology matches the service requirement information of the service request with the service-related information of each service registration request, so as to determine the target service registration request corresponding to the service request.

Fig. 3 is a schematic diagram of a service request in the blockchain-based cloud service management method provided by the present invention. As shown in Fig. 3, the cloud service provider sends a service registration request to the distributed cloud service network, and each service registration request includes The corresponding service-related information mainly includes service-related information such as service type, service quality parameter set, service resource amount, and service unit resource price. A smart contract in the blockchain will extract this information and write it into the blockchain, waiting for service requests.

Cloud users can initiate service requests to the blockchain-based distributed cloud service network, and each service request contains corresponding service demand information, including: various service attribute requirements (including functional attributes and non-functional attributes) for the target service attributes), resource requirements, etc. Service requests will trigger a service matching algorithm based on smart contract technology. The service matching algorithm will consider factors such as the maximum capital expenditure that the service requester (each cloud user) can bear and the optimal service quality of the service provider (each cloud service provider) to complete the best service matching.

The block chain-based cloud service management method provided by the present invention utilizes block chain smart contract technology to realize matching processing of service requests, and designs a block chain-based distributed cloud service management mechanism to ensure safe p2p resources trade.

In the single-user service matching scenario, among all the service-related information of the service registration request, determine the one with the highest matching degree with the service requirement information of the service request of the cloud user as the matching object;

In a multi-user service matching scenario, based on maximizing the total matching rate and quality of cloud users and minimizing the total matching price as matching goals, determine the target service registration request corresponding to each cloud user's service request.

Furthermore, in the process of realizing the matching operation of service requests based on the service matching algorithm based on smart contract technology, the cloud block chain network can realize the service matching algorithm based on smart contracts, so as to consider the service provider's service requirements based on user service demand information. Relevant information to achieve comprehensive matching.

Specifically, in the single-user service matching scenario, the service matching is completed by maximizing the matching amount of the user's service demand, and resource pricing is realized at the same time.

Since only one cloud user participates in the matching, it is only necessary to maximize the matching amount between the cloud user’s service demand information and any service registration request’s service-related information as the matching goal, so as to match the cloud user with the optimal cloud servant.

As shown in Figure 4, in the face of more common multi-user simultaneous service matching scenarios, the social welfare Turn it into a goal, and use service quality and service price as factors to achieve service matching.

For example, the goal of maximizing social welfare can be understood as: if there are 100 cloud users who send service requests at the same time to participate in optimal matching, then the maximization of social welfare refers to meeting the needs of cloud users to the greatest extent at the same time the maximum number of . For example: the first matching result is to meet the matching needs of 80 cloud users at the same time, and the second matching result is to meet the matching needs of 98 cloud users at the same time, then it can be considered that the second matching result is aimed at maximizing social welfare matching results.

Wherein, the quality of service may include attribute parameters such as service jitter rate, interruption rate, and response time. The smaller the jitter rate, the lower the interruption rate, and the shorter the response time, the greater the quality of service. The total matching quality can be understood as a comprehensive quality (such as an average value or an accumulated value) of matching qualities corresponding to all cloud users.

Wherein, the matching price is the difference between the desired price of each cloud user's service request and the service price of each corresponding cloud service provider. Generally speaking, the lower the matching price, the higher the matching degree. The average matching price can be understood as a comprehensive price (such as an average or cumulative value) of matching prices corresponding to all cloud users.

Furthermore, the service matching algorithm based on smart contract technology can also calculate the comprehensive reputation of each cloud service provider, the standardized service quality of each cloud service provider as matching parameters, and realize intelligent matching operations, which are not specifically limited by the present invention. .

The service management mechanism provides users with a better service selection platform.
