SCLOUDPY: Sistema Informático Web de Multi-Tenencia para el Procesamiento en la Nube de Pedidos de PYMES

Abstract

This article aims to describe the improvements made to SCLOUDPY, a web system of order flows management in supply chains. The idea is to achieve its expansion to a multitenant system which allows the system to operate in Cloud Computing mode. This allows serving several small and medium size enterprises (SMEs) ensuring the independence of data from these SMEs. To achieve these improvements various methodologies were applied as a DAR assessment (Decision Analysis and Resolution) to select the most relevant requirements, and XP agile methodology for software construction. Finally, a multitenant system that operates in the Cloud that meets the needs of several SMEs was obtained. At the same time the system does not represent additional costs because the system was built with free software. This combination of operating model and software architecture ensures an efficient and flexible system for processing orders.
