Problems solved by technology

The service cloud provides economical and convenient computing services through renting. Before the service starts, it is necessary to form a commitment between the supplier and the consumer through a negotiation mechanism. These commitments are regulated by the service level agreement (SLA), but usually the user The proposed service target has certain ambiguity or cannot be directly expressed as the measurement value of the service cloud that provides resources, and the service cloud cannot directly use these data for effective resource selection and resource allocation

Embodiment Construction

[0055]The implementation of the technical solution is described in further detail below:

[0056] Step 1: Establish the basic background of service level agreement SLA matching

[0057] Create matching background data by submitting their SLAs from the resource side and the user side of the service cloud:

[0058] 1.1), the service cloud resource end submits its available resources and the SLA (service level agreement) that can be satisfied to the cloud agent, and serves as the public service level agreement SLA pub Save, where the superscript pub means that the service cloud resource is published on the network, assuming that there are four service cloud resources submitting their SLA pub They are: {1200MIPS, 2M, 220M, $1} corresponds to CPU, memory, hard disk, and cost; {99%, 8ms, $1} corresponds to availability, response time, and cost; {1000MIPS, 2M, 98%, $1,96 %} corresponds to CPU, memory, availability, cost, and reputation, and {$1.5,99%,97%} corresponds to cost, avail...

Abstract

The invention relates to a service cloud evaluation method based on a service level agreement constraint. The method includes the steps that blur evaluation is conducted on a service level agreement of a service cloud perceived by a user, and a service cloud resource for meeting the individuation need of the user is given; by the adoption of the blur evaluation of the service level agreement given by the service cloud resource, the service cloud resource suitable for the user is selected, screened and recommended. The service cloud evaluation method based on the service level agreement constraint belongs to the field of cloud computing and innovative networks. The designed evaluation method for the service cloud resource can be applied to terminal users in the service cloud for achieving the optimum matching of the resource on a PaaS layer, and meanwhile the algorithm is simple and easy to implement.

Description

technical field [0001] The invention relates to a service cloud evaluation method constrained by a Service Level Agreement (SLA), which fuzzily evaluates the SLA of the service cloud perceived by users, and provides service cloud resources that meet the individual needs of users. Through the fuzzy evaluation of the service level agreement SLA given by the service cloud resources, the service cloud resources suitable for users are selected, screened and recommended. The invention belongs to the field of cloud computing and innovation network. Background technique [0002] The selection of service cloud resources is an important step in realizing service cloud automation services. The service cloud provides economical and convenient computing services through renting. Before the service starts, it is necessary to form a commitment between the supplier and the consumer through a negotiation mechanism. These commitments are regulated by the service level agreement (SLA), but us...
