Revitalizing an existing application is often the fastest, most cost effective, and lowest risk path to a "new" application. Existing applications are often constrained by complex, hard-to-maintain code, outdated architectures and/or aging technologies. Inhibited by quality and technology issues, these applications are costly to support. They lack the flexibility to incorporate advanced features and respond to the changing needs of the business. As a result, they often inhibit IT's efforts to be agile and improve business services. Application modernization offers an attractive alternative for rejuvenating and enhancing the business value of existing applications.
