Query system and method for accessing data centers through cloud platform

Abstract

The invention provides a query system and method for accessing data centers through a cloud platform. Different data centers are accessed in a unified mode through a central query cluster in the cloud platform, so that the cloud platform and the data centers are fused together effectively, high expansibility is provided, and the query accuracy is improved; when a user inquires a related result in a data center through the cloud platform, the user inquires in a query result cache module firstly; the result is returned directly to the user when the related query result required by the user exists; and when the result does not exist, query is performed through the data center, and then the query result is returned to the user and cached in the query result cache module simultaneously to facilitate user query afterward. Therefore, the resource utilization rate and the query efficiency are improved while the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and more specifically, relates to a query system and method from a cloud platform to a data center. Background technique [0002] In recent years, the most important change in the industry is cloud computing, which is also a major change that the industry will face. One of the many important parts of this change is the arrival of cloud platforms. At present, cloud platforms are mainly divided into three categories: IaaS Platform (hardware as a service platform), PaaS platform (platform as a service platform), SaaS platform (software as a service platform). Among them, the PaaS platform can provide the development platform required by developers in the cloud, including runtime environment, database support, feature service expansion, automatic deployment and operation and maintenance management. [0003] Cloud Foundry is the industry's first PaaS cloud platform launched by VMware in April...

Problems solved by technology

At the same time, under this solution, the outside world cannot obtain the resource data inside the data center. Although this improves security, in some scenarios, the enterprise still hopes to provide this part of the information data to the outside world. Incoming access connections, designing external access interfaces, and providing various development tool components for external access

This model will not only cause repeated construction of many enterprises, but also face a variety of data center interface tools, the learning cost of external developers is also very expensive, and the development efficiency is low.
