NoSQL Application Redesign may be Unnecessary for Most Corporation Cloud Migration Deployments

A great deal of cloud research implies that application redesign is a necessity in order to take full advantage of migration to the cloud, and developers are urged to consider migrating legacy application onto various NoSQL architectures. It may be argued however, that many enterprises have non-web-centric business models and relatively few of their applications may need the database scaling capability that cloud deployment with NoSQL affords. The authors contend that these corporations, in the process of cloud migration, are less motivated by the promise of NoSQL than by gaining greater operational efficiencies and cost-effectiveness. Several Cloud Infrastructure-as-a-Service (IaaS) migration scenarios for five top cloud vendors were studied using cost versus effectiveness ratios (CE). The results show that the greatest cost-benefit was gained by simply moving off physical resources and onto the cloud. This was coined the 'simple yet effective' model, as opposed to continuing along the technology curve to fully implement NoSQL solutions, coined the 'complex and robust' model.
