A safe and controllable method for public network access to virtual resources

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 method for public network access to virtual resources. Background technique [0002] With the rapid development of the cloud computing field, large-scale cloud service data centers continue to emerge. Among them, the cornerstone of cloud computing is virtual machine technology. At present, most cloud hosting operators put virtualized servers on the public network and rent them to customers. , the customer runs various network services on the virtual server. If the customer needs to remotely access and control the server, the operator must be required to provide the public network access authority of the virtual server, and the application for the cloud host needs to be activated in real time. Bring some new security and management challenges. As we all know, virtualized cloud hosts run on physical hosts, and use the network equipment of the physical host for network communication and access. At present,...
