Legacy Applications Maintenance

One of the biggest challenges for enterprise businesses is effectively managing legacy applications. The adoption of cloud technology has changed the way modern applications are built, but that doesn't mean you need to rebuild the code you have. The following tips can help you get a handle on understanding which cloud solutions are right for you and how to modernize code that needs to be updated:

Understand cloud technology's limitations

The biggest advantage of cloud solutions is that you only pay for the resources you use. Cloud solutions also enable companies to scale their resources in real time. Aside from reducing costs, these solutions provide businesses with virtually unlimited computing power. As discussed in InformationWeek, many enterprises rely on in-house solutions because traditional software-as-a-service applications can't handle the necessary scale. By using your own cloud infrastructure, you can ensure there is enough capacity for your software.

However, just because you can move code to the cloud doesn't mean you should. In an article from The Register, Correy Voo, president of the Open Data Center Alliance, advised financial institutions against cloud migrations because most code from the 1980s and 1990s was written to leverage limited amounts of resources. Another major obstacle to cloud migrations is transitioning from single-tenant to multitenant architectures. All legacy cloud migrations need code to be rewritten or tweaked, which is a costly and inefficient process. However, there is now a variety of automated modernization methods enterprises can use to help them move critical applications to the cloud.

Embrace dedicated resources

Because migrating legacy applications isn't a frequent task for enterprises, it doesn't make sense to divert in-house resources to it. Legacy code migration is a specialized task that requires extensive expertise. By implementing an automated modernization process, you can decrease project turnover, harden your code and optimize performance for new systems. Combing through code line by line is a formidable challenge for even the most experienced programmers, and automated modernization eliminates the repetitive tasks so your developers are free to focus on staying ahead of the competition.

Be proactive rather than reactive

Once you're past the legacy migration process, you'll need to plan for the years ahead. Technology is evolving rapidly, and what works today might not work in a few years. This is why you always need to stay on top of industry developments. Rather than spreading yourself too thin, working with an enterprise transformation and management partner enables you and your staff to focus on improving your bottom line instead of putting out fires.
