As cloud, freedom and big data continue to gain steam, making the most of your legacy applications can feel a whole lot like working with albatross around your neck. However, this doesn’t mean it is time. Instead, think about embarking on a legacy application modernization journey. When strategically planned and properly handled, modernizing custom legacy software might be low-risk, cost-effective means to conserve your critical intellectual property and optimize investments.
Of course legacy application modernization does not just happen. The best results occur when companies embrace a holistic approach that’s future-oriented and believes enterprise goals.
Let’s take a peek at what is involved in a successful legacy application modernization.
Honestly Rate Your Modernization Drivers and Willingness to Invest. If you’re seeking pure cost take-out or consolidation, pick a transformation approach that restricts functionality change and stresses fast, efficient and cost effective platform migration. If you truly plan to enhance the business gain or technical architecture of your applications, be ready to make the investment. Frustration and conflict can be injected into the process when project and organizational objectives aren’t aligned.
When planning for modernization, it is imperative to consider all job aspects upfront. Analysis should include existing IT structure and capacities, in addition to performance and business requirements. The goal should be to produce a 360-degree view of application usage, including how people operate the applications, what data they use, and how the applications have been modified over the years. This process generates a realistic view of how efficiently the legacy applications meet your organizational objectives today, and the functional interdependencies among all resources. It requires understanding to effectively map out the environment.
With a strong comprehension of where you are, and where you want to be, the upcoming strategic steps of legacy modernization focus on placing perspective into action.
Pursue Re-hosting. In several instances, especially if cost take out is your main objective, it is sensible to re-host custom applications, as well as packaged applications, infrastructure applications and databases from a variety of platforms such as IBM mainframes and proprietary UNIX systems. Taking this approach reduces complexity and enhances existing program and data value by moving your resources into a cost-effective platform.
The objective of re-architecture is to increase business value by upgrading the performance and constructs of legacy applications and data. As opposed to starting from scratch, this extensive redevelopment process eliminates the obsolete code in legacy systems that constrain agility, while improving current business-relevant functionality. Done right, re-architecting empowers your organization to rapidly adapt and react to changing business demands.
Understandably, legacy modernization requires commitment. Locating an experienced partner can often play a pivotal role in assisting you to achieve success and avoid potential pitfalls. However, done correctly, the results are worth the effort.
