DEBESŲ KOMPIUTERIJOS PROGRAMINĖS ĮRANGOS PASLAUGŲ GREITAVEIKOS TYRIMAI.

The paper presents the performance analysis of the developed software as a service. In OpenStack cloud infrastructure, the software services for hemodynamic flow modelling and particle technology applications have been developed by using Apache jclouds API. The performance of the hosted cloud infrastructure has been assessed testing virtual memory, CPU, disk IO, network and the developed software services. The measured performance of the virtual OpenStack resources (full XEN virtualization) has been compared with that of the virtual Eucalyptus resources (KVM paravirtualization) and the native hardware.
