Monitoring applications executing on a virtual machine and allocating the required resources to the virtual machine.

摘要

Disclosed is a method of running an application on a virtual machine executing on a distributed computer system. The application is executed on a reduced operating system configured for the application. The application is deployed on a first set of virtual machines with a first set of allocated resources. The method comprises determining a monitoring time period, and operational constraints for the application. Parameters of the application are monitored for the set period and time dependent values of the parameters collected. The values of the parameters are used to derive a time dependent metric value based on the operational constraints. If one at least one of the metric values violates one of the operational constraints a second set of resources and virtual machines are allocated and deployed for the application. The metric value may be derived by producing a mathematical function of the behaviour parameters and using the function to determine the metric value.
