Performance Analysis of Open Source Cloud Computing Architectures

Organizations prioritize cloud computing as the primary solution for ensuring secure and, most importantly, uninterrupted delivery of data. In today's landscape, there are various architectural frameworks offering cloud computing infrastructures to choose from. It is crucial to understand how advantageous the performance offered by a chosen architecture is when making a selection. This study aims to comprehend how effective open-source cloud computing architectures are in specific usage scenarios, provide a comparative perspective, and assist organizations in making informed decisions when selecting their IT infrastructures. In line with the study's objectives, the network, disk, and processor performances of OpenStack, OpenNebula, and Apache CloudStack architectures on the same hardware are examined based on data-driven methods. The Iperf3 tool is used for network performance measurement, the dd (Linux) tool for disk performance measurement, and the Sysbench tool for processor performance measurement. After conducting performance measurements with these tools, it was observed that the OpenNebula architecture outperformed the other architectures in terms of overall performance.
