Safety controllable method for accessing virtual resources by public network

Abstract

The invention discloses a safety controllable method for accessing virtual resources by a public network and mainly solves the problems of large potential safety hazard, low reliability, cumbersome work and difficulty in management in the process of accessing the virtual resources by the public network in the prior art. The safety controllable method for accessing the virtual resources by the public network comprises the following steps: a physical node creates more than one virtual network with a private network segment; when a user requests to create a virtual machine, the physical node distributes a fixed IP (Internet Protocol) for the virtual machine in the private network segment of a certain virtual network, adds the created virtual machine into the virtual network and acquires the designated IP; after the virtual machine user designates a network port which needs to be opened, the physical node distributes an idle port from a local port pool and the idle port transmits a network port access request onto the designated port in the virtual network to implement accessing. By the scheme, the safety controllable method for accessing the virtual resources by the public network fulfills the aims of safety, reliability and convenience for implementation and management, and has very high practical value and popularization value.

Description

Technical field [0001] The invention relates to a safe and controllable public network access virtual resource method. Background technique [0002] With the rapid development of cloud computing, large-scale cloud service data centers continue to emerge. Among them, the cornerstone of cloud computing is virtual machine technology. At present, most cloud host operators place virtualized servers on the public network and lease them to customers , Customers run various network services on virtual servers. If customers need to remotely access and control the servers, they will inevitably require operators to provide public network access rights to the virtual servers, and cloud host applications need to be activated in real time, which gives cloud computing operators Brings some new security and management challenges. As we all know, virtualized cloud hosts all run on physical hosts, and use the network equipment of the physical host for network communication and access. At present,...
