PvD: A Lightweight Distributed Monitoring Architecture for Cloud Infrastructures

Reliably running large server infrastructures requires continuous monitoring of system states. Nowadays, these infrastructures are often being executed on an IaaS cloud infrastructure. At its heart IaaS cloud computing heavily relies on virtualization technology spanning from virtualized servers to networks. Compared to a typical server setup, virtualization introduces at least one additional layer between the hardware and the guest operating system, thus introducing an additional layer of complexity which also increases the amount of services that need to be monitored to support the reliable operation of virtualized IaaS servers.
