TECH SHOWCASE Making the Case for Modernization Why updating applications makes good business sense By Shirley S. Savage very industry must be nimble, especially in today's competitive economic climate. But many enterprises may be reluctant to invest in more flexible legacy system applications, fearing that it will be expensive, time-consuming and involve many rewrites. Done properly, a modular approach to modernizing applications lets you change and update your application efficiently without losing valuable business logic. System z* and IBM i platforms have let clients run the same applications for more than 25 years, yielding unmatched ROI over time, notes Mark Even, opportunity manager for IBM System Lab 5 Drivers of Services-Power*. Modernization: However, if changes aren't made to User interface leverage the Maintainability potential value of Performance new technologies, Database clients might miss Globalization out. "Sooner or later, you need to bite the bullet and modernize. If you want to keep the application and the value it gives, you've got to modernize it," he says. E The Drivers The drivers of modernization fall into five categories: UI, maintainability, performance, database and globalization. 1. Right now, the most common business driver is the need for a new UI. Many enterprises find this upgrade necessary because of new users or new hires who are accustomed to GUIs. The move toward mobile also is a major reason companies are revamping their UIs. 2. The common technical driver for modernization is maintainability. Legacy architectures tend to be large, monolithic programs. Over time, Even says, it becomes harder to maintain them and add new functions that may be required by the business or by regulations. He adds that in some cases, skills availability only serves to compound this challenge. When the system can't respond quickly enough, it's time to break up these large program sets and modernize them using a modular approach. 3. Performance comes into play when clients face the demands of a growing business. Clients may become frustrated when the original architecture prevents applications from scaling up to meet increasing needs. When companies modernize, they can better optimize applications by leveraging new features and advanced technologies incorporated in today's operating systems and databases. 4. Modernizing databases yields performance results. Companies need databases that can handle new requirements with ease-especially with the recent push toward big data and analytics. 5. Business need is squarely behind the move toward NOVEMBER/DECEMBER 2014 // 29
