Performance Barriers to Cloud Services in Africa’s Public Sector: A Latency Perspective

Conference paper
Part of the Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering book series (LNICST, volume 275)


Cloud computing allows individuals and organizations to lease storage and computation resources remotely and as needed. For such remote access to work efficiently, there is need for reliable and low-delay delivery of Internet traffic. By carrying out month-long Internet measurement campaign, this paper investigates location and latencies of cloud-based web hosting in the public sector of five African countries. Results of the study show that a large percentage of public sector websites are hosted in cloud-based infrastructure physically located in America and Europe. Analysis of latencies shows significant differences between local and remote hosted websites, and that delays are significantly lower for countries that host CDN nodes. The results also indicate high delays for local websites that are accessed circuitously.
