What is a Legacy Application and why are organizations still using it?

A legacy application is a software program that is regarded as outdated and obsolete because it was developed using technology that is much older than current trends. Although a legacy app still works, it may be unstable because of compatibility issues with current operating systems and browsers.

 

There are assorted reasons why an organization should keep a heritage or even an old application. It may be difficult and costly to replace, particularly in a vertical market with unique feature needs, or the operational hazards of a big scale update may be too great, especially if crucial data is in danger of being lost or damaged.

 

For example, Microsoft stopped supporting all versions of Internet Explorer (IE) before version 11 at the beginning of 2016. Users who are still using IE 6 can do so, however, webpages will no longer be created to be compatible, and any flaws or defects in the program will not be addressed by Microsoft, leaving any versions older than IE 11 obsolete software.

Challenges with Legacy Application

  1. Non-Responsive UI/UX
    The UI of the old program was not responsive and was difficult to use.
  2. Scale Inability
    Additional causes include because they are no longer updated, heavily patched, cannot be scaled, or there are no competent people inside the organization that know how it works.
  3. Cloud deployment
    Cloud technology is becoming more popular as contemporary emerging trends. There was no cloud migration with older or legacy applications possible.
  4. Emerging Technologies
    Legacy applications cannot keep up with evolving technological developments, thus they must be upgraded to reflect current trends.
  5. Inflexible Architecture
    An inflexible application architecture design was used by the legacy application, which made it unusable. Due to its rigid structure, the legacy application was not user-friendly.
  6. Spaghetti Code
    As a result of the spaghetti code in the Legacy application, it was possible to replace it with the latest and exact code. As opposed to an app that uses an array of old technology and code, a legacy app may not be appropriate in the current environment.
  7. Monolithic & Time Consuming
    The maintenance of historic programs is both time-consuming and inefficient since they are monolithic and cannot be upgraded or adapted.
Why Modernize Legacy Application?

Application Modernization is the process of transforming outdated programs into a new and improved appearance and functionality. Application Modernization restructures a legacy app into a modernized app using recent technology. This includes newer languages, frameworks, and infrastructure platforms.

 

So, why is it necessary to upgrade legacy applications? Because businesses must accept change – It is truly a case of adapting, or perishing. To summarize, we upgrade outdated software & applications to save money, assure security, prepare for new business prospects, or battle for survival in extreme instances.

  • Enriches Customer Experience

The new and powerful algorithm-based application is easy to understand, user-friendly, and simply accessible to the app function. If the application is simply available to the clients, it improves the customer experience and attracts additional clients. For example, if your consumer cannot discover the appropriate way to navigate through the application fast, it might lead to customer dissatisfaction and lead to you losing business.

 

When compared to traditional or legacy applications, it can supply the best experience to the customer’s visits on the app.

 

A customer experience plan is a never-ending process. Adopt a strategy of continual improvement. Remember that the customer experience offers a huge chance to increase client loyalty.

  • Enhance Application Performance

When you use obsolete technology, you may experience sluggish loading times, poor UI/UX, and difficult maintenance and upgrades. This all has an impact on overall system performance.

 

Application Modernization allows the business’s IT backbone to become more scalable, adaptable, and easy to manage. Organizations may dramatically enhance app performance by utilizing the newest tools and technologies, such as faster load time, greater service speed, optimal user experience, minimal downtime, and the capacity to manage a larger workload, also deployment in the cloud.

  • Cost Reduction

Because legacy apps have been in use for a long time. It is also quite expensive to keep the legacy app running. Whereas the legacy app after modernization might be on different platforms and it also enables you to reduce so many unnecessary charges that will help you save.

Let us have a quick overview of the statistics that highlight the importance of modernizing your legacy applications that are critical to an organization’s business operations and help in reducing the cost.

  • 15-35% approx. Infrastructure year-over-year savings.
  • 30-50% approx. lower application maintenance costs.
  • 74% approx. Minimal costs on hardware, software, and organization staff.
  • 10% approx. improvement in overall operational efficiency.
  • 14% approx. yearly net revenue for large organizations.

One of the most notable advantages of the upgrading process is cost reduction.

  • Data Security & Safety

Older systems are more vulnerable to threats and weaknesses. Organizations may better manage security provisions and lower the risk of attacks and data fraud by installing innovative and modern technology.

 

To gain the trust of their consumers, businesses have begun to prioritize data compliance and regulatory norms. Modernization helps them to meet regulatory obligations while also guaranteeing their customers the highest security levels.

  • Improved UI/UX

The UI/UX is more than appealing for the new customers to use it. When you modernize legacy UI/UX, you reduce the learning curve for new workers and provide them with more value & flexible architecture. In simple words, UI examines your app’s overall appearance, visuals, and design.

  • Adopting Emerging Technologies

App modernization extends the application’s lifespan. Your organization may profit from the latest technology & clearly redefine coding by implementing application modernization in the legacy applications.

  • Reduced Manual Dependency:

Application modernization refers to solutions that are designed to automate the bulk of processes and eliminate duplication or repetitiveness. Organizations can reduce unwanted workers and become more productive and tech-savvy with this solution.

Techniques Involve in Application Modernization:

It is becoming more difficult to keep up with technological updates and upgrades as technology evolves daily. Application modernization is a technology that influences an organization’s capacity to adapt to changing business environments.

 

Application from Legacy to Modernization is more than just moving Legacy applications to modern Applications. To remain competitive, many organizations use a combination of Legacy and modern applications. The definition of modernization varies by industry.

 

  • Data Migration

It is regarded as the primary technique employed in the app modernization process. Organizations can expand apps more efficiently and affordably with public, private, and hybrid cloud services than with traditional IT infrastructure.

 

  • Containers

The main advantage of containerizing applications is that they can be packaged in lightweight, consistent ways so that they can run consistently on desktops, clouds, and on-premises systems.

 

  • DevOps

DevOps is a popular approach across most organizations for upgrading applications. DevOps promotes cooperation across multiple teams, resulting in faster delivery, greater dependability, speedier go-to-market, and production stability.

 

  • Microservices

Microservices is one of the techniques that deal with service-oriented architecture (SOA). By building loosely coupled services, rather than creating monolithic applications, your application becomes more flexible and supportable.

 

What you are doing with Microservices is taking a large monolithic software and decomposing it into smaller apps that you can easily, rapidly, and independently change, adapt, and redeploy.

 

  • Analytics & AI

It improves the precision and quality of apps. Integrating artificial intelligence & analytics into apps improves accuracy. AI improves the efficiency and effectiveness of the application. It enables the acceleration of tailored, customer-focused marketing.

 

The relevance of UI/UX in app modernization cannot be overstated since most app designers use these characteristics consistently to create dynamic apps. Most application users nowadays choose apps with simple and speedy navigation.

How? 7 ways to Modernize Legacy Applications

There are 7 ways to modernize Legacy applications to find a suitable cost-effective solution for businesses:

  • Encapsulate
    Encapsulation means Modernizing an application begins with encapsulating it into smaller services applications to break down monolithic applications.
  • Rehost
    Lifting an existing application and transferring it to a more powerful infrastructure environment without re-design or restructuring is called rehosting.
  • RePlatform
    Replatforming is a method for modernizing applications that maintains the core functionality of the application but customizes and optimizes its overall functionality to achieve a tangible outcome.
  • Refactor
    Refactoring is the same as Rehosting, but with some features added to Legacy components during the refactoring process.
  • Rearchitect
    This method can be costly, but if you can sustain digital transformation, it can prove to be fruitful. This method is one of the more complex methods to re-imagine how application architecture is designed and conceptualized with cloud-native tools to incorporate modern technologies.
  • Rebuild
    In rebuilding, the entire application component is rewritten from scratch. It is redeveloped in a manner that preserves the original specifications of Legacy applications are designed in the same way as rearchitecting, but rather than remodeling, they are created from scratch.
  • Replace
    It includes a completely new application including a new structure, features, scope, and functionality. In this model, more robust and scalable technologies such as Cloud computing are deployed to reduce cost and improve productivity.
