Problems solved by technology

But in reality, the software and hardware resources of each node are often different, including the type, version, patch, function library, application environment, etc. of the operating system.
This makes it difficult for applications running on it to migrate freely between nodes

Embodiment Construction

[0032] The method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] 1) Modeling the scheduling problem of server applications in the cloud environment

[0034] The traditional bin-packing problem (bin-packing) is a widely studied NP-hard problem, which requires a series of items in the range (0, 1] to be packed into the least number of boxes of size 1. This problem There are various variants, such as the online bin packing problem, which requires the minimum number of bins to be packed without knowing the sequence of upcoming items; the semi-online bin packing problem, which allows, on an online basis, Every time a new item arrives, the position of the original item is adjusted; the multidimensional box packing problem, the size of the item and the box is expanded into a multidimensional vector; there is also a box packing problem that allows the item to leave halfway, and so on.

Abstract

The invention provides an internet application dispatching method based on cloud computing, and the method comprises the following steps: 1) a dispatcher which is installed at the front end of application servers monitors the configuration information of the application servers, the application requirements on each server, the user request number of the previous moment and the current moment and the operation information of all examples in each application server; 2) when the change of the application is monitored, the server load with the changed application is adjusted by utilizing the load descending of the application, an application logging-out system, an application adding system and the load ascending of the application through a packing algorithm, and a transponder modifies the load distribution among the examples of each application, thereby reducing started new application examples on a new server; and 3) the dispatcher outputs the application example which needs to be closed, the application example which needs to be started again and the server on which the application examples are started. In the method provided by the invention, the service number of resources is dynamically adjusted for users according to the dynamic requirements of the user application; the new application examples are avoided from being started to the greatest extent; and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and relates to a cloud computing resource scheduling method, in particular to a cloud computing-based Internet application scheduling method. Background technique [0002] The emerging cloud computing model in recent years has become a hot issue in industry and academia. The traditional computing model is that each user maintains its own server computing resources and storage resources. Cloud computing is a brand-new application model. Cloud computing vendors provide online services to customers, enabling centralized management of computing resources, and users can obtain cloud computing resources on demand. Cloud computing service quality is one of the current important research issues. Under the cloud computing model, how cloud computing vendors provide users with a stable service environment has become an urgent problem to be solved. [0003] Cloud computing centralizes the ma...
