Abstract
To keep software compatible and optimal with respect to the latest trends is not easy. Nearly 90 % of the software cost can be due to maintenance, and approximately 75 % of it is spent on developing new features to stay functionally competitive and relevant. The industry progresses through periods of incremental development interspersed with true paradigm shifts, and, therefore, legacy software must keep up the pace. However, software modernization is not a trivial issue, and, if improperly done, it dangers the business continuity and sustainability. Companies considering transition to the new paradigm of cloud computing need to have available an innovative and combined technical and business analysis on the maturity and prospect of the legacy application. This chapter presents an approach for assessing the maturity of these applications and the convenience of migrating to the new cloud paradigm. Two issues are taken into account: on one hand, the perspectives in terms of technical challenges, maturity, and effort of the migration are identified; on the other, the performance and business benefits in relation to the cost of the process are pre-evaluated before tackling the actual migration process. Perhaps, for the first time, the business value is directly attached to the technical performance.
