How to build an application modernization strategy
Application modernization is an umbrella term encompassing a wide variety of strategies, including re-platforming, re-hosting, re-coding, re-architecting, re-engineering, interoperability, replacement and retirement, as well as changes to the application architecture to find which option should be selected. Your application modernization strategy should be all about innovation. Enterprises need to close the modernization gap or else they won’t be able to keep up with the evolving industry, competitors, and ever-changing technology.
Modernizing legacy applications is a significant undertaking. Starting the process with an in-depth assessment of your legacy application portfolio, and determining the best course of action based on its findings, will help businesses ensure they’re choosing the best strategy for their needs. By performing a gap analysis, you’ll be able to identify exactly where your weak spots are and use them to begin mapping out a strategy.
Additionally, your organization’s budget and risk tolerance are both important factors in constructing your application modernization strategy. For example, a complete system rebuild or replacement might solve your application issues, but may be unsuitable due to expense or time constraints. These are the types of factors you need to identify through analysis so you’re not hit with major roadblocks later down the line.
Since it can be incredibly frustrating to choose the wrong approach to application modernization, consider testing out a small application first. This test run will help inform your strategy by providing insights into what may or may not work best for your individual organization. There are different ways to approach application modernization, from reprogramming to partially rewriting to containerizing for the cloud. Nailing down which of these is best for you is a crucial aspect of defining clear, set path to modernization.
That being said, while a drastic strategy might seem appealing, remember that this is an ongoing task - legacy modernization is not a one-time event. Once your system is completely replaced or updated, it will still need to evolve along with its competition and consumer expectations of the digital sphere. Maintaining applications on a hybrid cloud can be an excellent way to retain what worked about your original application while making space for new priorities like enhanced security, cost savings, or better capabilities for integration with external APIs.
