Debesų kompiuterijos programinės įrangos paslaugų greitaveikos tyrimai / Performance analysis of cloud computing software services

Abstract

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.


Santrauka


Straipsnyje pristatomos sukurtos debesų kompiuterijos programinės įrangos paslaugos (SaaS) ir jų greitaveikos tyrimai. „OpenStack“ debesų kompiuterijos infrastruktūroje jclouds priemonėmis buvo sukurtos hemodinaminių srautų modeliavimo ir dalelių technologijų tyrimų diskrečiųjų elementų metodu programinės įrangos paslaugos. Debesų kompiuterijos infrastruktūros efektyvumas buvo ištirtas testuojant virtualios operatyviosios atmintinės, virtualaus CPU, virtualaus standžiojo disko, virtualaus tinklo ir sukurtų programinės įrangos paslaugų greitaveiką. Atliktas kiekybinis „OpenStack“ visos XEN virtualizacijos resursų greitaveikos palyginimas su „Eucalyptus“ KVM paravirtualizacijos resursų ir grynos aparatinės įrangos greitaveika.


Reikšminiai žodžiai: debesų kompiuterija, programinės įrangos paslaugos, „OpenStack“, jclouds API, greitaveikos tyrimai.
