1. A method of controlling a number of instances of an application running in a computing environment, comprising:
- monitoring a current load on an application running in the computing environment, wherein the current load comprises at least one indicator of a level of usage of available instances of the application, and wherein the monitoring comprises monitoring a current number of instances of the application;
altering the current number of instances of the application running in the computing environment based on results of the monitoring; and
specifying a minimum number of instances of the application;
wherein the monitoring comprises monitoring the current number of instances of the application for falling below the minimum number of instances for at least a predetermined amount of time.

Abstract
The number of instances of an application running in a computing environment are controlled by monitoring the current load on the application, and altering the current number of instances of the application based on results of the monitoring. The load may be monitored by monitoring the current number of instances of the application running in the computing environment. Where a maximum, minimum and/or initial number on startup, of instances of the application are specified, the altering is done based on comparing the current number to one or more of the specified numbers of instances.
