Abstract

The invention discloses a global load balancing method and system based on a dual-active architecture and a scheduling server. The system includes: a first data center and a second data center of the dual-active architecture, and a scheduling server; wherein, the first and second The WEB layer switches of the data centers are all connected to the scheduling server through the Internet; the scheduling server is used to periodically obtain the resource status of the WEB servers of the first and second data centers from the WEB layer switches of the first and second data centers; and Determine the domain name after receiving the domain name resolution request sent by the user; look up the IP address and resource status of the server mapped to the domain name from the DNS resource record table, and filter out the IP address of the server to return; when one of the data centers fails, Mark the WEB server in the data center as down. The present invention can provide a global load balancing service for cluster service nodes with a double-active disaster recovery architecture.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a global load balancing method and system based on a dual-active architecture and a scheduling server. Background technique [0002] With the increase in business volume, the explosive growth of access and data volume, the computing power of a single server can no longer meet the data access requirements, and various distributed computing technologies have emerged as the times require. In order to give full play to the performance of each server node and improve resource utilization and operating efficiency, it is necessary to coordinate the work of each node in an effective way and balance the load of each node.
