  Cloud computing is becoming common, and the choice of proper infrastructure
is essential. One of main issues is choosing between private and public clound,
between commercial and non-commercial solutions. This paper aims to compare the
parameters of OpenStack and Google Cloud systems. Both systems deliver a
computing cloud service, enabling the user to use the infrastructure as a
service (IaaS) model. We developed the pipeline using the Python programming
language and its libraries, which enable communication with the aforementioned
clouds. We measured various parameters of instances and task execution:
instance launch and deletion times, and their dependence on the number of
launched instances. Moreover, we used benchmark algorithms to check the
instance performance. We analysed the results and the factors that contributed
to them and provided conclusions, recommendations, and suggestions for further
research based on the gathered data.
