METHOD AND SYSTEM FOR APPLICATION MIGRATION DUE TO DEGRADED QUALITY OF SERVICE

摘要

A method and system for managing an application in a cloud data center by monitoring the bandwidth of a subnet of which the primary operating instance of an application is a member. If a severe deterioration in the bandwidth caused by an over consumption of the subnet resources from other subnet constituents is detected, a suitable secondary instance in an alternate, uncompromised subnet is located and primary operation of the application is transferred from the former primary operating instance to the secondary instance. The secondary instance can be pre-launched or dynamically requisitioned according to various embodiments.

1. A method for managing operation of an application to avoid degradation of quality of service, comprising:
monitoring execution of a first instance of the application executing in a first computing environment for a degraded quality of service, the first instance of the application comprising a primary operating instance of the application; detecting a degraded quality of service corresponding to the first instance of the application, the degraded quality of service comprising a deterioration of bandwidth available to the first instance of the application; determining a bandwidth available to a second instance of the application executing in a second computing environment located in a different subnet of a computer network from the first computing environment; and migrating primary operation of the application from the first instance of the application to the second instance of the application when the bandwidth available to the second instance exceeds the bandwidth available to the first instance of the application.
