AUTOMATED SCALING OF APPLICATIONS IN VIRTUAL DATA CENTERS

摘要

A system and method for autoscaling a multi-tier application, that has components executing on a plurality of tiers of a virtual data center, allocates resources to each of the plurality of tiers based on cost and performance. An application performance is determined, and a new application performance is estimated based at least partially on an application reservation and an application limit. An optimized utility of the application is calculated based on the cost to execute the application, the application reservation, and the application limit. A scaling factor for each tier is then determined to scale up or down a number of virtual machines operating in each of the tiers.

1. A method comprising:
determining a performance of a multi-component application distributed across a plurality of tiers; estimating a new performance based on at least one processing resource parameter for the application; calculating, via a processor, an optimized utility of the application based on a cost to execute the application and the at least one processing resource parameter; and determining a scaling factor for each of the plurality of tiers.
