The graph depicts the cost-benefit comparison between rehosting and modernization. While the cost parameter may vary based on the size of the project, the percentage difference remains the same. Rehosting refers to the migration of an on-premise IBM iSeries application to cloud which might seem to be a very cost-effective option when compared to modernization.
Even after rehosting, the application still runs on the old programming languages like RPG/COBOL due to which businesses face challenges such as high overhead cost for maintenance/ enhancement/support, unavailability of subject matter experts, maintenance and support resources in RPG, green-screen user interface etc. Considering the changes in modern business, the transformation of legacy systems to modern technologies will be unavoidable soon. The rehosting of applications is an expensive, time-consuming process and will only provide a temporary solution. Therefore, IBM i modernization is the right choice to transform legacy applications to new technology or platform, with same or enhanced functionality by adopting multiple software architecture models.
Businesses are on the lookout for a mobile version for every application as it is convenient for users, saves more time and money. The modernization of an iSeries application makes it easy to migrate into mobile platforms like IOS and android. Based on recent market predictions, it is expected that due to higher inflation rates retention and maintenance of legacy systems would be a costly affair. Hence it's in the best interest of the business, to modernize legacy systems in the IT infrastructure by effectively utilizing the hybrid methods of IBM i series modernization.
We at Vofox are passionate about bringing in the right transformation in our client’s business through the best IBM application modernization techniques. We believe that many current business challenges can be effectively addressed through IBM i modernization and help companies achieve a high ROI.
