Load balancing method and system on basis of double-layer cache

Abstract

The invention provides a load balancing method and system on the basis of double-layer cache. The load balancing method includes steps of presetting a memory manage module and a disk management module in a webpage server and setting parameters of the memory management module and the disk management module; acquiring data information required by terminals by inquiring the memory management module after the webpage server receives requests of the terminals and feeding the data information back to the terminal; keeping inquiring the disk management module if query is failed, and acquiring the data information requested by the terminals and feeding the data information back to the terminals. By the load balancing method and system, probability of response to the requests of terminal users from the network layer is increased, request dispatch to the backstage application server cluster is reduced, and request pressure of backstage servers is alleviated. Meanwhile, the number of the backstage application servers is decreased, and the purpose for reducing investment and cost is achieved.

Description

technical field [0001] The invention belongs to the field of load balancing, and in particular relates to a method and system for load balancing based on double-layer cache. Background technique [0002] With the continuous expansion of the performance requirements and reliability of web servers, more and more enterprises use load balancers to enhance the concurrency capability of web services, and achieve the goal of increasing system reliability by building parallel clusters. The computing resources of the enterprise's web services are increased. If the number of background application servers is blindly increased, it will not only increase the cost for the enterprise, but also cause a waste of resources. [0003] Most cache media are memory caches. As we all know, the price of 16GB memory sticks is already very expensive, and with the increase of memory capacity, the price of memory increases exponentially and the web server motherboard limits the upper limit of memory ca...

[0002] With the continuous expansion of performance requirements and reliability of web servers, more and more enterprises use load balancers to enhance the concurrency of web services, and achieve the goal of increasing system reliability by building parallel clusters. Increase the computing resources of the enterprise's web services. If the number of background application servers is increased blindly, it will not only increase the cost for the enterprise, but also cause a waste of resources.

[0003] Most of the cache media are memory caches. As we all know, the price of 16GB memory sticks is already very expensive, and with the increase of memory capacity, the price of memory increases exponentially and the motherboard of the web server limits the upper limit of memory capacity. Therefore, relying solely on It is also difficult to increase the memory capacity of the web server to enhance the concurrent capability of the web server, and the high price is often unaffordable
