Method and system for application migration in a cloud

Abstract

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 in the cloud data center.

Description

technical field [0001] The present invention relates to cloud computing management, in particular, to a method and system for application transplantation in the cloud. Background technique [0002] Cloud computing is poised to revolutionize the current computing paradigm in the near future. In general, cloud computing refers to the deployment and use of computer technology over the Internet where computing resources from a larger set of shared computing resources can be dynamically requisitioned as services over the Internet. Cloud computing differs from other similar computing paradigms: such as utility computing - this is due to the fact that cloud computing consumers do not have to have (and are often excluded from) knowledge, visibility into the actual technical infrastructure used to deliver the services they receive and control. [0003] Typically, cloud computing providers provide clients with the ability to access or lease these resources at an agreed upon rate. T...

AI Technical Summary

Problems solved by technology

[0011] The same techniques employed to detect and combat direct DoS attacks may not be available and / or effective when indirectly affected by applications in the same subnet or applied to indirectly affected applications in the same subnet

This problem can be exacerbated by the structure and lack of visibility within the cloud

Furthermore, the same technology cannot effectively address the problem of legitimate, high-traffic users simply using up the capacity of the network

As DoS attacks originate from within the cloud infrastructure, legitimate cloud consumption running on only a relatively small amount of computing resources can take a crippling amount of a subnet's data transfer capacity
