Cloud resource situation perception system structure

Abstract

The invention discloses a cloud resource situation perception system structure. The cloud resource situation perception system structure comprises an IaaS layer, a PaaS layer and a SaaS layer. The IaaS layer comprises various units for directly providing situational information, and the situation information may come from hardware equipment or software services or people. The PaaS layer comprises a situation perception engine, a storage tank and a Collaboration Module. Situation information models, inference rules, configuration models and business service interfaces used by the situation perception engine are stored in the storage tank. The SaaS layer comprises various business services provided for users, wherein the business services can be Webservice or can also be entity services in real life. By means of the cloud resource situation perception system structure, cloud resources comprising calculating, storing, calling, inferring, safety, querying and other function modules at the service layer can be distributed according to needs.

Description

technical field [0001] The invention relates to the fields of cloud computing and perceptual computing. Background technique [0002] In the cloud computing environment, all resources and applications will be integrated on the "cloud", and each learner can use these resources and applications to freely create a virtual community, build their own virtual learning environment, and share common learning goals Collaborative learning with other learners. However, (1) services are scattered and difficult to maintain. Decentralized management of data will result in duplication and redundancy of data. (2) The on-demand allocation of resources cannot be realized. Since the service is relatively independent and the demand for the service is uncertain, there may even be untimely and uneven service responses. (3) In most cases, the load is very low, but a large amount of electric energy is wasted. Therefore, a solution needs to be found. Currently, there are three specific solutio...

AI Technical Summary

Problems solved by technology

However, (1) services are scattered and difficult to maintain

Decentralized management of data will cause data duplication and redundancy

(2) The on-demand allocation of resources cannot be realized

Since the service is relatively independent, and the demand for the service is uncertain, there may even be untimely and uneven service response

(3) In most cases, the load is very low, but a lot of power is wasted

[0006] Through analysis, solution (1) mainly focuses on the establishment and reasoning of the situation model, and the architecture is not based on the computing method of the Internet, and does not consider the on-demand allocation of cloud resources and information; solution (2) when the environment, task or situation changes , resource mapping and effective use of cloud resources can only be performed on the premise of manual intervention by users; (3) The framework includes connection management, component management, service discovery, message processing, user interface and context storage structure are too complex, cloud resource acquisition delay Longer, less efficient and less accurate

These three schemes fail to sense the dynamic changes of the internal / external environment, and with such changes, perform static adjustments and dynamic evolutions according to functional indicators, performance indicators, or reliability indicators, so that the system has as high a user experience as possible. satisfaction
