What Is Application Modernization and Why Keep the Tech Stack Up to Date

Business application modernization isn’t just about rewriting an app from one programming language to another. It’s the process of converting a legacy system into a modern infrastructure, architecture, and features.

Let’s say your company uses an outdated CRM system from the times the business was relatively small. As the company grows, you may need to add new features like searchable invoice history or quick invoices to clients.

Old monolithic suits are not capable of upgrading—you’d either have to use a different tool or continue to issue invoices manually. Not to mention errors and critical issues the old software starts throwing in time.

In this case, application modernization may refer to moving to cloud-based architecture to introduce new modules and features faster, changes in the security model, and UI update.

UI/UX design often has to change to adapt to new standards and business requirements.

When we were modernizing RetailOps, a SaaS retail platform, our clients asked to make the platform easy-to-use for workers with vision issues. We reengineered the app and completely changed its UI/UX design, making the app not only performant but accessible for any employee.

An 'old' system doesn't always mean a 'bad' system. It's rather connected with whether the old suit can process modern (digital) operations, be scalable, and supported without huge expenses.

For example, when the software is written in antiquated programming languages like COBOL or Visual Basic, it’s harder to support it.

That was actually the case with ten US federal systems in need of modernization (the full list includes 65 systems, some of which date back to 70s). Many of these solutions rely on COBOL, have various support issues, and security vulnerabilities.

You need developers to support such systems—fix bugs, monitor security breaches. And it’s much harder to find a programmer these days who knows COBOL or Visual Basic than developers who work with Java or .NET.

Indeed lists only 401 jobs for COBOL developers. For Java developers, there are 28,143 jobs on the same resource.

Finding developers for business application modernization may seem complicated—you need qualified programmers who already worked on similar cases.

You may start with choosing between three hiring options:

• Hiring a freelance developer
• Assembling an in-house team
• Outsourcing app modernization

Hiring a freelancer is cheap but good only for small one-time projects—making a landing page, fixing a bug, adding a shopping cart to your website or mobile app.

Applications modernization in a large-size company doesn’t actually fit the description. You’ll have to hire several freelance developers (if you don’t want the process to take years), a UI/UX designer to update the software interface, and manage everyone not to mess up the whole process.

Working with an in-house team is a more reliable but much more expensive option. You’ll have to look for qualified developers, interview them, rent an office, pay for software and hardware, and bare lots of other expenses.

If you have enough time, financial resources, and years of work ahead, hiring an in-house team is justifiable.

But if you’re constrained by budget or time limits, try looking for offshore development companies. They’ll provide you with a full team of developers, UI designers, QA engineers, assign a PM—and their services will cost much lower compared to an in-house team.

According to the Public Cio report, outsourced modernization is the second popular option.

Besides, many outsourcing companies offer post-release support—full updates, bug-fixing, redesign, app scaling.

Here are the most common reasons for modernization:

Let’s discuss some of the most popular reasons.

In 2019, the US government planned to spend more than $90B on IT services. About 80% of this amount went towards maintaining legacy systems.

More funds go to supporting old systems, less—toward the development of new solutions. Here's how much it costs to modernize old systems vs. continue to maintain them:

Modernization of enterprise-level applications does come with a price tag. But a new MMIS system pays off in just ~2,5 years—and at once eliminates UX issues, frequent outages, and issues with meeting today's security requirements.

Just as technology and software become more advanced, so do cyber threats. Viruses, malware, and attacks are critical for outdated software as cybercriminals know their weaknesses and exploit them.

According to the Symantec report, outdated applications are more vulnerable to security threats and data breaches. That’s because software updates often include patches for newly discovered security threats that could be exploited by attackers.

If you're using healthcare or financial product, the software must comply with HIPAA, PCI, SOX, and other standards. And they require your technology to be supported.

In case you experience a data breach in a system that deals with personal or financial details (which is very likely due to security holes), you’ll have to deal with penalties. Healthcare data breach, for example, costs $6.45M.

Legacy software does not fit in with the needs of today’s customers and employees. Especially when it comes to remote operations.

Take the banking sector, for example. Digital channels are boosting in the financial industry. There are already 57M mobile banking users in the US, and Bank of America app is an industry leader with 25M mobile users.

If a bank is sticking to old software while its competitors adopt new digital solutions, it won't be hard to lure away some of their customers.

Besides, by introducing an up-to-date solution, you're attracting new customers and making your employees more productive.

According to a Forrester study, developers that work with modernized applications are 40% more productive. The right choice of technology can help make engineering teams more efficient and improve time-to-market.

So, there’s a need to modernize your business applications—and quickly. How to complete modernization without cost overruns, missed deadlines, and project cancellations?

Start by reviewing what you already have. As soon as you access your current application, you can start making plans to increase its value by modernization.

As we've been on the market for 6+ years, we had a few projects regarding applications modernization.

I’ve briefly mentioned RetailOps—a SaaS retail platform we’ve upgraded. We worked with an old-versioned iOS app written in Cordova instead of native iOS-language (Swift).

Our Design team created a perceivable UI/UX design, and we used the right contrast color scheme our clients requested. We finalized the features RetailOps already had and added new functionality.

You can learn more about RetailOps in our portfolio case or case study.

Another example of application modernization was an internal CRM system we’ve worked on under NDA.

Initially, the software was written in out-of-date PHP. It was impossible to add new functionality and maintain the system, so we rewrote the software from PHP to JS.

Our clients got a stable and customizable CRM system—they still use it for internal processes. The solution is scalable, so our clients can easily add new features as their business grows.
