Legacy modernization

  1. 1. Legacy ModernizationAs hardware capabilities rapidly evolve, critical applications are presented with a difficult scenario. Eventhough hardware advancements help boost functionality and performance to a large extent, they alsomultiply the complexities involved. The expanded software requirements tend to add fragility and increasecosts involved in the system’s development.Changing the software in order to take advantage of such increased capacity is definitely not a cheapaffair in terms of the costs involved. Moreover, if the technology used to build the software is poor interms of scalability, the applications will be difficult to maintain and prone to errors.The solution to this problem lies in Legacy Modernization, also known as Software modernization. It issimilar to migration from one platform version to the other, like ASP to ASP.NET migration. The termsrefer to the conversion, rewriting or porting of a product platform or legacy system to a modern computerprogramming language, software libraries, protocols, or hardware platform. Legacy transformation helpsyou gain more agility. It aims to retain the value of the legacy system through migration to new andadvanced platforms. These are two of the major reasons why the appetite for software modernization isgrowing and organizations are beginning to recognize the need for it.The Need to ModernizeCost is one of the major reasons that lead to organizations opting for modernization. However this is notthe only reason why people want to move to modern Microsoft development and .NET developmentplatforms. The decision to modernize can be related to many circumstances, like retaining the value ofthe legacy application, vendor dependence, poor integration capability of the system, long time to market,low agility or lack of trained personnel in the labor market. Organizations are often seen moving tomodernization due to lack of strategic flexibility.Legacy Modernization TechniquesRe-engineeringLegacy applications can be re-built using new and advanced technologies and platforms with the same orenhanced business functionality in a Service-Oriented Architecture.Re-hostingLegacy applications can be employed using this non- invasive method onto a contemporary platform toreduce high maintenance cost of applications on legacy platforms.IntegrationData in a service-oriented approach can be unlocked from closed architecture legacy systems to providenew access channels.Package implementationThis involves replacement of legacy applications with modern, off-the-shelf packages or ERP software.
  2. 2. Benefits of modernization  Lets you invest more in business growth  Reduces the cost of running your business-critical applications  Improves rate of return  Moves your applications easily to the cloudLegacy modernization is a complex process and needs a considerable amount of prior planning andprogram management. While the transition takes place, integration issues may also be faced bybusinesses. Therefore, it is essential to have an integration technology in place before modernization isplanned or executed. When a legacy mega-application is broken into many different pieces that includenewly written applications, various purchased or licensed applications, etc., it resul ts in businessprocesses which span multiple applications. These newly-purchased and newly-written systems need tobe connected back into the existing corporate applications and data.Integration technology can help leverage cost savings and other benefit s like elimination of unsupportedhardware and software. It also frees up people and cuts down on budgets that can further be repurposedwithin IT to provide better support for the business.
