Web request load balancing method based on operating system virtualization

Abstract

The invention discloses a Web request load balancing method based on operating system virtualization. The present invention firstly collects and normalizes server resource information; secondly collects server and service instance dynamic information; then calculates the final weights of service instance copies of all services according to server resource information and periodically collected dynamic information; Poll for distribution requests. The present invention can effectively avoid different service instance copies on the same server, and the server is overloaded due to the low load of the server receiving a large number of Web requests at the same time, realizes the load balance between the service instance copies and the servers, and improves the concurrency of the Web cluster system ability to reduce the average response time of requests.

Description

technical field

[0001] The invention belongs to the technical field of Web cluster load balancing, and in particular relates to a method for balancing Web request loads based on operating system virtualization. Background technique

[0002] With the rapid development of Internet applications such as social networks and e-commerce, network servers are faced with the following two problems: (1) the number of visits increases exponentially; (2) transaction processing becomes more complicated. In order to deal with the above problems and provide users with a high-performance network service environment, a distributed Web server system (Web cluster) emerges as the times require, and is used to replace a single Web server with high performance. In a web cluster, each type of service contains multiple service instance copies, and multiple service instance copies of the same service are hosted by multiple different servers. In order to distribute user requests to different service ...
