What is App Modernization?

App modernization

It is referred to as legacy app modernization when you take your existing app and update its infrastructure, architecture, and features. However, let’s talk about the benefits of app modernization. You can say that it can generally be used to enhance the pace of the latest feature distribution, revealing the capability of current programs so that they may be accessed via API by external businesses.

Replatforming apps from on-premises to cloud for application scalability, speed, and long-term information center and IT strategies. Usually, the costs and difficulty of application modernization are the biggest obstacles. Apps should not be moved from on-premises to the cloud only for the sake of transferring them.

In contrast, numerous applications may gain significantly from a single switch or rearchitecting but are so tightly integrated with current architecture and systems that the burden of modernization may overshadow the benefits.

As with most issues, the secret to application modernization achievement is a strategy and choosing ventures where the advantages of the cloud, velocity, efficiency, size, latest feature development, etc., are such that allow the current application a concrete route to enhanced user experience and Return.

6 Strategies to Modernize Your Legacy Apps

Every organization should undertake seven-step legacy app modernization strategies while selecting the best modernization approach.

Legacy System Evaluation 

If your legacy app system is not contributing to your business in this modern landscape or is the roadblock to your success, it needs modification. Similarly, modernization is necessary if any application is pumping up the entire cost of ownership or you sense an undue risk.

Point Out the Problem

If it’s not serving your organizational or IT needs, it’s time for you to filter the problem further. It implies that you need to find out what is actually causing difficulty for your customers or employees. There’s a need to target users’ stories specifically.

But, you should also find out about what is serving well in the legacy system or what does not need a change. When you know what works and what doesn’t, it is going to be easier for you to decide on the modernization approach.

Assess Your Modification Options

App modification options

Once you know that your legacy applications are in dire need of modernization and you see where the problem resides, your next move is to determine how you would modernize them. There are seven approaches through which you can update your app:

  • Retain A minimal-risk method of incorporating legacy application elements into a new design. The legacy program is encased or coated, and an API is used to reach it as a service. This method also allows for gradually growing the program using a microservices strategy.
  • Rehost: It entails “lifting and shimmying” application elements to other infrastructure with no (or little) changes. Moving an app from an on-premises system to the cloud is frequently the quickest method.
  • Replatform: This method transfers the current code to a revamped platform with a few restructuring while keeping the existing code’s structure, attributes, and functionalities.
  • Refactor: Refactoring goes beyond optimizing the code and making structural modifications to the code (restructuring) to reduce some of the technical debt that causes problems with legacy software and may include out-of-date libraries, frameworks, and regulations or unfinished or ineffective functionality.
  • Rearchitect: Rearchitecting entails making large code changes in order to move a legacy program to a more advanced framework.
  • Rebuild: Redesign or rebuild the program from zero, but keep the structure and requirements the same.
  • Replace: If a legacy system stops functioning for several business objectives, it’s relevant to reconvene, analyze the issue, and identify the best product to address it. The legacy app will be retired with this strategy, and a thorough product development strategy will be used.

The Select App Modernization Approach 

In order to select from the options mentioned above, apart from effort and impact, you can assess your choices regarding them: 

  • Working load
  • Architecture
  • Cost for modernization as well as continued operation
  • Risk
  • Operations
  • Security

The importance of each of them will revolve around their precedence for every company. However, the competition and altering customers’ demands can also contribute to the value of each and every approach.

Be Ready for Future Growth and Alterations

No firm functions in a void; they are also going through a continuous change in a competitive marketplace, economic environment, and the chances of technological advancement. The average lifetime of any app is normally 6 to 8 years.

Today’s legacy system is inflexible, making it difficult for organizations to update their applications. The digital age we live in requires significant agility to launch the latest features and capabilities to maintain balance. When selecting the right modernization approach, you are actually choosing the greatest adaptability to alter things when needed.

Ensure You Researched Well While Selecting Your Partner

Organizations often do not build or modify applications all the time or, let’s say; it’s not included in their priority list. Your team may not have the required expertise to fit into the new environment and need the training to use the latest system. So, would it be possible to have enough means to make all the right decisions?

For this purpose, several companies count on a credible software partner to help them in modernization projects. Find a group that utilizes Agile and DevOps principles for your modernization program to maximize time-to-market.

Important Reasons Why You Need App Modernization

Yes! There was a time when legacy applications were enough for businesses, but now the situation is different. If you are still relying on the legacy system, that could be the reason your company is not profiting or gaining any kind of benefit. Below are some important reasons why you need app modernization.

  • Advancements in your technology can provide you with competitive dominance. Remember that you won’t need them just for your company’s prosperity but also to compete. You know that everybody nowadays is going for digital business transformation as it has become a necessity at this time.
  • Having advanced technology can provide better opportunities for future growth, whereas outdated technology could be the reason hindering competence. The effort you would want to maintain your existing system could be better served by creating new approaches.
  • You will be provided with better security measures as it is one of the most important elements of digital transformation. We all know that security systems advance continuously, and legacy systems easily become the victim of cyber attacks. So, isn’t it better than legacy systems?
  • As the customers see a modification in technology, their demand and expectations increase as time passes. They could tell the difference between your legacy or modified systems even if they were not directly engaged with your legacy apps.
  • As the cost of maintaining legacy apps is not apparent, businesses often get confused about how much it would cost them. Maintaining outdated apps can be a waste of money and effort, so why not spend them on other things such as advancing obsolete technology?

Lead Drivers for App Modernization

Saving Expenses

If you are still using legacy apps, you would know it comes with several obvious expenses and some unrevealed ones too. The most obvious among all is maintaining legacy apps, as you know how difficult it will get to maintain them as time passes and new modifications and technologies will arise. These apps may consume more time and effort than you could have spent on developing a modernizing strategy.

Some companies spend huge amounts maintaining outdated apps; even half of their IT budget goes to keep legacy tech working. And it doesn’t stop there; the budget will keep rising as time passes. Additionally, finding people familiar with your legacy system won’t be easy when the old workers retire.

However, there’s also a cost that we don’t discuss: the competitive advantage you lack over your competitors. You outlook so much on the enhancement of the corporate earning, productivity, and efficiency that contemporary digital technologies provide. It is the drawback of sticking to outdated, antiqued solutions.

Rapid Alterations Pace

It makes sense that modernization would enable you to adapt more quickly and reduce your time to market, as outdated technology is restricting your technological capabilities. One benefit of investing less in legacy IT upkeep is that you’ll have much more money for development. In exchange, getting access to cutting-edge technologies allows you to outperform your rivals and draw in and keep loyal customers.

Enhanced Scalability and Shared Processing

The process of app modernization allows you to be more scalable and facilitate shared processing. Many firms are particularly engaged in fragmenting and separating their single unified legacy apps into linked microservices. The flexibility of this strategy is quite advantageous.

Every microservice is more manageable since it is shorter. Unlike an unyielding centralized program, when one microservice breaks down, the remaining application is less expected to be negatively impacted.

Liberation from Confining IT

A big driver for app modernization efforts is the need to be freed from constrictive IT and software licensing. Most businesses get weighed down and stuck with processes and systems buried within old technology. For instance, 76 percent of firms claim to have information locked up in antiquated systems that prevent them from connecting to cloud computing.

Updating your old programs can frequently free you from these restraints and offer additional options for developing your IT ecosystem. The old .NET Framework is only compatible with Windows and is private. But if we talk about .Net core, it is an open source which implies that any user can make modifications in their source code to meet their needs.
