Application modernization – A Competitive Advantage

April 19

Have you ever wondered why technology initiatives don’t move as fast as business needs? A simple statistic justifies it: in 2020, the application market should have an estimated legacy of between 7 and 10 billion dollars while modernization will continue to grow at an amazing rate to 20 billion by 2023. In .Net and Java alone, they should be modernized close to 9.3 million apps, a huge difference.

Small and medium-sized businesses (SMB) are in a risk group. There are four critical points that these businesses need to be aware of in order to remain competitive: infrastructure, applications, data, and sales. A major obstacle to maintaining an up & running business occurs when application modernization loses its ability to ensure continuous delivery of positive experiences to the end-user. When this process is well structured, it mitigates the risk of losing support from legacy environments, changes are quickly implemented, operating costs are reduced and systems operate properly.

To eliminate technical debt and overcome the challenges that hinder the growth of your business, it is essential to modernize or optimize your applications.

What are the main challenges of legacy applications?

According to Gartner, 40% of the IT budget will be consumed to pay the technical debt. The future of Information Technology departments must be classified as a source of innovation, and not just as an operation and training center. Therefore, our challenge is to be able to reduce costs, increase flexibility, quality, and agility in launching or updating new applications.

When we analyze it in this way, it is clear that it is important to eliminate the technical debt of the application layer by modernizing or optimizing these applications. The maintenance of these legacy applications (which use old architectures or languages) tends to become increasingly expensive and difficult to maintain, in addition to having direct impacts on the company’s productivity and effectiveness.

Application maintenance

How open is your IT area to business requests that involve changing applications?

In many companies, when there is a disruptive idea or a need to change the process to take advantage of a business opportunity, employees are faced with numerous challenges, such as plastered processes and long lines of requests to the IT and purchasing department. And when trying to keep up with the tools available, they encounter outdated applications that do not meet current challenges. These problems are aggravated when it becomes a project with established dates and deadlines.

This list of problems could be avoided if all of your company’s applications were up to date with their maintenance, or were replaced by more modern versions, at the moment they started to become obsolete.

Slow down business growth

When a business starts to grow, the number of transactions increases as much as the number of records in the databases, so the response time must be agile and work at the same speed as your demand. Does this happen in practice?

It’s easy to spot when you have processing spikes or really need a big infrastructure all the time. The truth is that it is often underutilized and at certain times its capacity is not sufficient. The ideal is to have a platform that adapts to the elastic needs of your business.

Maintenance of the code

As time passes and updates bring new features, it is normal for the code to start to get messy. Often, development teams end up changing and projects end up suffering from this variation, making it even more difficult to understand the code and its structure. The older a system, the older its development and the more difficult to maintain. For systems that must be updated in line with changes in laws and regulations, this is a chaotic scenario.

Lack of tests

Another very common problem among legacy systems is the lack of a structure for carrying out tests. In current applications, it is very common to have a part directed only to tests, which will guide any small or big changes.

Tracking an error that occurred in an application due to lack of testing is a slow and difficult process. Often, even finding the fault, we are not always able to track all of its damage, decreasing the team’s productivity.

Technological lag

When building a system, it is common to use libraries, plugin models and other technologies that may have been discontinued by the manufacturer, that is, there is no more support. Something like this can happen even with the programming languages used in a system, which stop being updated and end up losing space in the market. With that, we face not only difficulties in the development of new features, but also in finding qualified labor.


Legacy systems were built on top of an outdated computational architecture, that is, even if the code has been very well written, there will be difficulties in obtaining all the computational power, which adapts to current needs. For systems that use a lot of processing, this difficulty directly affects their performance, making these applications much slower.

Lack of skilled labor

Finally, another great difficulty in dealing with legacy systems is the lack of specialized labor for these applied technologies. As these professionals are rarer, it turns out that hiring them is much more expensive than the common labor force, which works with current technologies, making maintenance of legacy applications more expensive.
