摘要：Many business applications are designed and organized to supp ort business activities for a period of time and to be renewed at the turn of the period. Design changes are typically implemented in a revision of the application that supports future periods to assure smooth operation . Very often the applications suppor ting the previous periods need to be operational continuously even after the application for the new period started. Parallel operation of current and previous periods' applications may be problematic for web - based applications due to the rapid change in Internet technologies. Cloud computing provides a solution to this problem with the capability of offering virtual servers with user - specified configurations. This paper propo ses a parallel archiving scheme that uses virtual server to run each period's a pplication in a cloud platform so that previous periods' applications will run in parallel with the current period system and forms an easy - to - access archive for historical data.
