Legacy Application

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.

Vocal User Interface

Although Graphical User Interfaces (GUIs) often improve usability, individuals with physical disabilities may be unable to use a mouse and keyboard to navigate through a GUI-based application. In such situations, a Vocal User Interface (VUI) may be a viable alternative. Existing vocal tools (e.g., Vocal Joystick) can be integrated into software applications; however, integrating an assistive technology into a legacy application may require tedious and manual adaptation. Furthermore, the challenges are deeper for an application whose GUI changes dynamically (e.g., based on the context of the program) and evolves with each new application release. This paper provides a discussion of challenges observed while mapping a GUI to a VUI. The context of the authors' examples and evaluation are taken from Myna, which is the VUI that is mapped to the Scratch programming environment. Initial user studies on the effectiveness of Myna are also presented in the paper.
