Abstract
The race to keep software compatible and optimal with respect to the latest trends is hard. 90% of software cost can be due to maintenance, and 75% on developing new features to stay competitive and relevant. The industry progresses through periods of incremental development interspersed with true paradigm shifts. Legacy software must keep up the pace.
At present we are experiencing one of these paradigm shifts, as remarked by the EC [1] “The speed of change in Internet technologies continues to be impressive. Software is becoming more and more pervasive: it runs on the devices that we use every day ... [opening] a new world of possible applications”. Today, technological and business model innovation generates large demand for the transition of legacy software towards modernization. However, software modernization is not a trivial issue and if improperly done, it dangers the business continuity and sustainability.
This means that for any company meditating about the transition to the new paradigm of cloud computing, there is a need to have at its disposal an innovative and combined technical and business analysis on the maturity and prospect of the legacy application. The major target of this process is to identify in advance the perspectives of the migration and pre-evaluate the performance and business benefits with relation to the cost of the process. For the first time, the business value will be directly attached to the technical performance.
This paper presents this aforementioned approach, being currently developed and tested, in order to assess the maturity of an application and the convenience of migrating to the new cloud computing paradigm or not, based on quantitative indicators while always ensuring the company’s business continuity. Following this approach, questions such as cost and effort of the migration, impact of new business models in the company or return of the investment will be provided in advance of tackling the actual modernization.
