Cloud modernization is not new. According to a recent survey, over 51% of organizations who responded are in the midst of application transformation and cloud migration. Many businesses have moved at least somewhat to the cloud. However, moving custom applications off-premises remains a holdover in many organizations.
If your organization is experiencing any of the following pain points . . .
. . . then now may be a good time to reconsider modernizing your aging, custom software.
But how do you identify the benefits and justify the cost of rewriting these applications? How do you guarantee that newer equals better and that you haven’t dug your organization into a hole?
This article presents a more practical approach to application modernization by selectively identifying the pain points of existing applications and prioritizing a phased approach using specific cloud technologies. All of this gives you a clearer return on investment. It’s an approach we’ve successfully used with clients to develop cloud modernization project plans.
Many application rewrite efforts are born out of statements like:
Ask why to any of these questions, and you will get a myriad of responses, most of which are justified and based on industry best practices.
But it is not good enough to simply make these statements in isolation. We must always review the software in context and make the best decision possible for that application. Only then will it be clear which framework is the right choice, which cloud services to leverage, and which features are best suited for standalone microservices.
Most discussions about cloud migration or modernization of this application will consider the entire application, which is a mistake.
Figure 1 shows a hypothetical application broken up into four modules with four features in each module. Microservice patterns were designed to make the best architectural decision for the smallest unit possible. As you can see, this highlights our core pitfall. When discussing app modernization, always review each feature independently.
Often in such a review, you will find most of the application is meeting the needs of your business, but certain other areas are struggling. Those are the features that should be prioritized and discussed in detail to ensure any modernization addresses the areas of need.

Figure 2 shows the same hypothetical application with several “hot spots” – areas of pain within the current application. After isolating issues in specific features, it is much easier to make informed decisions.
Such analysis will often result in one of the following outcomes:
Our experience designing app modernization plans tells us that your application modernization initiative will have a greater chance of success when you use the second, more deliberate approach to app modernization. This approach can reduce costs by only rewriting what needs to be optimized rather than trying to rewrite and rework the entire application.
In this article, we presented an alternative to costly re-architecture projects that don’t seek to understand the business challenges upfront. Making well-informed business decisions and understanding and correlating those decisions to the right technology is critical to differentiating your business from your competition.
