Studying performance barriers to cloud services in Africa's public sector

Published On -

Cloud computing allows individuals and organisations to remotely lease storage and computation resources as needed. For such remote access to computational resources to work efciently, there is a need for well-developed Internet infrastructure to support reliable and low-delay delivery of trac. By carrying out the month-long Internet measurement campaign, this paper investigates the hosting situation and latencies in the public sector of ve African countries.

Results of the study show that a large percentage of the public sector websites across the countries are hosted in cloud-based infrastructure and are physically located in America and Europe. Analysis of delays shows signi cant di ferences between local and remotely hosted websites, and that latencies are signfi cantly lower for countries that host CDN nodes. The results also suggest higher delays for local websites that are accessed circuitously.
