Abstract

The present invention discloses a cloud host domain name dynamical configuration method and system. The method comprises that when a cloud host is started, a cloud host management platform selects a public network IP from an IP resource pool, allocates the public network IP address to the cloud host, requests a domain name service (DNS) server to establish a domain name record of the cloud host, indicates an exit device of a cloud data center to configure network address translation (NAT) table items of the cloud host, the NAT table items including a mapping relation between an intranet IP address and the public IP address, and allocating the public IP address distributed to the cloud host onto the exit device; a client end acquires the public IP address corresponding to a domain name of the cloud host from the DNS server, and addresses an access request to the exit device based on the public IP address; and the exit device inquires the NAT table items to acquire the corresponding intranet IP address and address the access request to the cloud host. Cloud host domain name dynamical configuration can be realized.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and system for dynamically configuring cloud host domain names. Background technique [0002] Cloud host is an independent computing unit generated by using virtualization technology on cloud computing hardware resources, including elements such as computing, storage, and network. It has an independent operating system and can be created, run, and deleted in the cloud. Cloud host business is a new generation of host rental service, which can fully meet the needs of small and medium-sized enterprises and individual webmaster users for host rental services with low cost, high reliability, and easy management. Amazon Elastic Cloud Computing (Elastic Cloud Computing, EC2), Alibaba Cloud Elastic Cloud Service (Elastic Compute Service, ECS), and China Telecom all provide cloud hosting services. [0003] One way of providing cloud host domain name configuration function in the prior...
