On the suitability of black-box performance monitoring for SLA-driven cloud provisioning scenarios
Arnaud Schoonjans, Dimitri Van Landuyt, Bert Lagaisse, Wouter Joosen · 2015
In recent years, cloud computing has become an increasingly important software delivery paradigm, mainly for reasons of increased scalability. The scalability benefits are accomplished by the capability of autonomously and elastically scaling up or down so that customer preferences (SLAs) can be accommodated. For this, performance monitoring is a prerequisite. Distinction is made between white-box and black-box monitoring techniques: the former involves collecting information about the monitored component by looking at its internals, while the latter only involves observing the components interfaces.
