WISE-SPL: Bringing Multi-tenancy to the Weather InSights Environment System

Abstract

Weather conditions affect many cities and companies. The WISE (Weather In Sights Environment) system serves as a central place to gather and present weather related information for decision makers. It was initially developed to fit a single tenant. Due to a multi-tenant opportunity, WISE is evolving to be deployed on a Cloud environment to support on-demand computing resources and multiple clients. Software product line techniques were applied to model common and variable features of tenants. WISE-SPL enables the derivation of products for each client and also the deployment on Cloud infrastructure. The contribution of this work is a demonstration and discussion of benefits and limitations in applying SPL techniques, following a extractive approach, to build a multi-tenant Cloud application.
