Why do 70% of the companies listed on the Fortune 1,000 list ten years ago no longer exist today? Inflexibility. They couldn’t adapt to change. In the past, big companies ate small ones. Now, fast eats big.
With that in mind, it’s no wonder that CIOs list legacy modernization as one of their top priorities. Legacy applications aren’t flexible. They don’t quickly adapt to change. As such, companies that rely on these applications lack flexibility, which…kills companies.
Hence, the growing push towards modernization. Application modernization promises flexibility. It frees these companies from the shackles of their legacy software.
The problem: Modernization isn’t exactly straightforward. There’s more than one way to modernize. By my count, there’s five. How do you know which way is best?
Here are a couple of resources that will help you answer that question. First, here’s a free whitepaper entitled, “Crash course in modernization” that explains the need for modernization and outlines your options. Second, we put together a handy comparison chart based on that white paper, which you can find below. It compares your modernization options side-by-side, and helps you determine which is best for your company.

One more thing: What happens if your company is tied to your legacy applications? What if they’re too expensive, time-consuming, or risky to replace? If you feel stuck, don’t worry. There’s a way to bring flexibility to your existing legacy applications (without replacing them), which you can read about right here.
