Embodiments of the present invention relate to the use of event processing (e.g., for complex events) in a cloud infrastructure using Statistical Process Control (SPC) techniques to detect changes in a holistic system. Specifically, events (e.g., complex events that occur over multiple layers in the architecture) may be detected and/or correlated by an event processor. Thereafter, an SPC engine will determine if the events impact a set of SLAs based on a set of Key Performance Indicators (KPIs), which are measurements indicating actual performance of the cloud computing environment versus stated goals. The SPC engine will then determine if a set of actions is needed to address the events to avoid the SLAs terms from not being met. If so, a provisioning engine can carry out any needed actions. |
