Experiences with on-premise open source cloud infrastructure with network performance validation

Abstract

When looking at cloud computing, aside from the commercial solutions like Amazon Web Services and Microsoft Azure, there are also promising open source alternatives. In this paper, our hands-on experiences are summarized with consuming, deploying and managing an on-premise Infrastructure as a Service (IaaS) cloud solution based on the open source OpenStack platform in combination with Ceph as a distributed storage solution. We introduce means on how to achieve high-availability of this small-scale on-premise cloud infrastructure solution and provide network architecture and storage recommendations. Finally, performance measurements of these network and storage solutions are presented, indicating observable throughput and latency differences between the various configurations.
