SYSTEM AND METHOD OF MONITORING AND MEASURING PERFORMANCE RELATIVE TO EXPECTED PERFORMANCE CHARACTERISTICS FOR APPLICATIONS AND SOFTWARE ARCHITECTURE HOSTED BY AN IAAS PROVIDER

摘要

The present disclosure is directed to a system for monitoring and analyzing operation of a widely distributed service operated by an Infrastructure-as-a-Service (IaaS) tenant but deployed on a set of virtual resources controlled by an independent IaaS provider. The set of virtual resources provided to the IaaS tenant by the IaaS provider is hosted on a set of physical resources selected by the IaaS provider, and both the set of virtual resources and the set of physical resources can change rapidly in both size and composition (i.e., the resources are “ephemeral”). Although the monitoring system may not have visibility into the composition, configuration, location, or any other information regarding the set of physical resources, the monitoring system can evaluate the performance of the virtual resources and infer that a virtual resource within the set of virtual resources may be hosted on at least one physical resource that is underperforming.
