A New Framework for Method-Level Dynamic Software Updating
Dynamic Software Updating (DSU) is a necessity in the operation of a large computing infrastructure that must deliver high availability. An issue very relevant to the industry is that legacy applications running in data centers were often designed and constructed without due consideration for the need of partial upgrades in the future. The goal of this research is the development of a framework that allows for an automatic retrofitting of legacy applications to enable a selected set of individual methods to be dynamically updated. This framework will rely on the use of aspect-oriented programming to facilitate the specification of the functions that should become dynamically updatable and to automatically rebuild the application in a way that allows for the dynamic updating of such functions.
