Application Modernization: Revamping the Legacy applications.  

The outmoded features of many legacy applications and software hinder business growth to the next level. This stammering leads to pulling down the business growth while another application with advanced technologies emerges into the market. As technology evolves every nanosecond, a legacy application with outdated features doesn’t reach and attract users to access the application or software, shrinking business growth. 


Application modernization transforms Legacy applications into new versions, accelerating the business with upgraded features according to recent market trends. You can bypass the hurdles in modernizing Legacy applications into new applications through this article. 
What is Application Modernization? 
Application modernization is a process to improvise the outdated features in Legacy applications with new languages, frameworks, and infrastructure, such as migrating the application towards cloud storage, refactoring the coding sections, and so on. It is also renowned as Legacy Application Modernization.

Best strategies for Application modernization  

Modernization of applications allows Legacy applications to stay free from many outdated constraints. There is a myth buzzing that Application modernization consumes money, time and team-related hurdles. FreeTechCafe expertise replaces this myth with effective revamping solutions globally. 
While focusing on the best strategies, an eye on failure aspects is also mandatory. Some key aspects lead to failure in application modernization,  

  • Improper training and Inadequate skills. 
  • Lack of communication between business and technical teams.  
  • Frequent changes in an organization’s hierarchical structure. 
  • Inaccurate project expectations. 
  • Lack of smart technologies. 

Let’s have a glance at Application Modernization strategies to transform legacy applications. 
Coordinate the modernization efforts with business goals  

Analyse the business goals based on current market trends and requirements. This practice helps revamp the outdated application with high reliability, scalability and performance, which enables users to access the application effectively. 


Implement required approaches according to needs  

The application modernization possesses six approaches; Refactor, Rehost, Re-platform, Rearchitect, Replace and Rebuild. According to business needs, you can choose the best approach to skyrocket your business revenue.  

For instance, Refactor the high-priority application majorly for cloud migration. The rehosting approach will be practical, where the developers don’t need to change the code.   


Assemble effective project timeline  

Prepare a modernization timeline based on project goals, tasks, updates, and duration of revamping, deployment date. Accordingly, the development team can discuss project tasks, figure out and align the priority works, and track progress.  

With the help of modernizing plan tools such as GanttPro, Hive, ClickUp etc., planning the procedures will be super easy. The tools will support,  

  • Estimate the timeline of a project  
  • Specify success metrics  
  • Exhibit project milestones  
  • Tasks allocated for concerned resource persons and tracking their productivity  

Choose architecture for long-term sustainability.  

Make sure the application can integrate with other systems without technical interruptions and ensure scalability and security.       

Make a checklist for choosing architecture based on   

  • Prepare a proper workflow or structure.  
  • Ignore or look for an alternative architecture if it restricts the application to any cost.   
  • Choose architecture that effectively works with DevOps, DataOps, Cloud and other automated procedures.   

Break down as chunks to reduce the risks  

The process of revamping at a time is difficult, risky and exhausting. To limit the risk factors, break the process into minor chunks and prioritize the high-demand requirement.    

Benefits of breaking down as chunks,   

  • Allocate the different segments of the application to the concerned team according to the roles.  
  • Analyse the existing application modules to revamp the particular segments if necessary. 

Utilize Software estimation models  

Applications or software need updates and upgrades according to the current trends in the market changes. Most business owners believe investing one time in an application or software is enough for the entire business process. This ideology will lead to the application or software being insecure. Modernising the application or software increases high security, reliability and scalability, ultimately saving time.  

Here are some models that enrich Application modernization  

  • Functional Point Analysis is a standardized method to size the software product’s work functionality and what the user requests and receives in return.  
  • Putnam model lets the organization forecast and get the exact estimation of modernization cost.   
  • The Constructive Cost Model, also called the CoCoMo model, is a regression model based on lines of code used to estimate the production cost of the application.  

Document the entire process  

Make sure to record every report of the revamping process for future use—document every development process detail from planning to deployment and maintain it in every phase of updates.    

  • Elaborate on the relevant features and required updates.   
  • Predefined and mark the amount of time allocated for developing an application.   
  • Update any changes or modifications done in the document. This documentation will enhance the exact workflow of modernization and revert for future purposes.   

 Speed up the tasks with automation  
Prepare the modernization plan to speed up the software development lifecycle and provides value to the company in minimal time. Here are some of the keys to automating the app implementation.   

  • DevOps is to speed up the automation and collaboration tools for quick data modifications and app delivery.    
  • Likewise, DataOps aims to speed up the data delivery to concerned data analysts and scientists for gathering insights. 

Spotting the difficulties with performance metrics  

The technical team maintains and monitors the application’s performance after the successful deployment. Here are some performance metrics to scale the functionalities of the revamped application.   

  • Response time – The amount of time to process a request and respond. 
  • Throughput – The number of requests processed per unit of time. 
  • CPU Utilization – The percentage of CPU accessed by an application.   
  • Memory usage – The memory accessed by the application. 
Define and Train the team for specific strategies  

With proper guidance and assistance, the developing team updates the new features in the application. 

Based on the application’s hierarchy, the technical team analyze the key factors and updates the features according to recent trends and requirements.  

Quick Summary 
The business world is transforming from Legacy applications to Modernized applications for high robustness, security, reliability and scalability to increase end-user application access. Though Application modernization is highly required, revamping where it requires matters. From the phase of planning to deployment, maintaining the quality of the application with updated features, documentation of the entire process, and estimating and analyzing the perfect cost for revamping are considering factors while moving to application modernization 

To be precise, the ultimate objective of application modernization is to replace the significant vulnerabilities, risks, threats and complexities in Legacy applications.   

As a business owner, correlate your application with recent trends and user’s intentions. If your business application meets the recent trends or needs of end-users, the application access will increase the business graphs.
