A data communication method and device based on hybrid cloud

Abstract

The embodiment of the invention discloses a data communication method and device based on a hybrid cloud, and the method comprises the steps: judging whether a last login node is recorded in server nodes of a private cloud or not in a login process; if yes, detecting the availability of the logged-in node; if yes, logging in the logged-in node to carry out data communication; and if not, obtaininga node list from the main service node of the public cloud, and selecting a first available node closest to the current terminal position in the node list to log in. When it is judged that the last logged-in node is recorded in the server nodes of the private cloud and is available, the logged-in node is logged in for data communication, communication service can be provided independently under the condition of network disconnection, and data safety is guaranteed. When the logged-in node is unavailable, the node closest to the current terminal position is selected to log in according to the node list of the main service node of the public cloud, unified deployment and management are facilitated, and expansion of server nodes in the private cloud is facilitated.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a hybrid cloud-based data communication method and device. Background technique [0002] With the development and maturity of cloud computing, more and more enterprises have begun to migrate their business to the cloud, forming various "industry clouds". For example, in the field of online education, companies have migrated their education services to the cloud to form "education clouds" with various architectures. [0003] Like other industry clouds, education cloud can be divided into public cloud and private cloud according to the deployment method. Public cloud: Unified deployment in the cloud, all schools and users access the same set of services through the Internet, providing infrastructure (such as machines, networks, database storage, etc.), which can be third parties such as Alibaba Cloud, Microsoft Azure, or companies Own machine room. Private cloud: Deplo...

AI Technical Summary

Problems solved by technology

[0004] The public cloud has low cost and good scalability. It can integrate upstream service providers and downstream end users to create a new value chain and ecosystem. However, the disadvantage is that it has poor security and cannot meet various regional or organizational regulations. Fees can add up quickly during traffic spikes

Relatively speaking, private cloud provides higher security and customizability, but the cost of implementation and maintenance will be higher, and remote access is more difficult
