Sustainability forecast for cloud migration

In this paper, a sustainability driven approach is proposed to measure the viability of cloud migration. The decision on cloud migration is based on sustainability dimensions, i.e., economic, environmental, social and technology, and risks associated with in these dimensions. We use Analytic Hierarchy Process and fuzzy scale to prioritize the sustainability dimensions based on a migration context to calculate Total Sustainability Index (TSI). TSI is then used to determine the viability of cloud migration according to three different scales, i.e., convincing, moderate, and ineffective. Finally, we used a practical migration use case from Ministry of Health (MoH), Malaysia to demonstrate the applicability of our work. The results from the studied context concluded that economic and business continuity are the key influential concerns for a sustainable cloud migration.
