The challenges of legacy applications can be grouped into such spheres as:

Troubled enhancements and new functionality introduction

Complicated and costly maintenance

An enterprise’s hindered digital transformation

Reduced business efficiency

Still, diving into the development of a new solution from scratch is hardly an option as it will require significant time and budget.

During 5 years of the software development experience, we've learned how to keep applications relevant and beneficial for the business and can help you to get through the modernization challenge smoothly and efficiently.

Applications We Modernize

We help to rejuvenate enterprise applications for:

Customer relations management.

Supply chain management.

Order processing.

Billing and invoicing management.

Financial management.

Marketing campaign management.

Collection and analysis of business information (business intelligence) and more.

Modernization Services We Offer

Application modernization consulting

We thoroughly investigate your legacy application code and infrastructure, mine requirements and provide detailed guidance on the improvements that can help you to derive max value from previous investments.

Application re-hosting

We move the application from the on-premises or the old cloud infrastructure to the new cloud (AWS or Azure). This is a fast and simple migration option to enable DevOps, ubiquitous access and optimize the usage of hardware resources that also streamlines more advanced modernization in the future. However, re-hosting offers just limited cloud-driven benefits in terms of app resilience, performance and scalability.

Application re-platforming

We complement moving the application to the cloud with the introduction of small modifications and upgrades in code that will bring more advanced cloud capabilities (improved performance, scaling, fault-tolerance, etc.) to the application.

Application reengineering

We reverse engineer, re-structure, modularize your application or their parts to make them live up to your new business requirements. This allows for:

Mobile enablement to extend the app’s reach and answer the needs of the on-the-go time.

Fitting Continuous Integration (CI), Continuous Delivery (CD) and other DevOps practicies.

Creation of web services.

The introduction of new functionality.

Enhanced app understanding to simplify future maintenance or replacement.

An upgrade of certain aspects (like performance, response time).

Application recoding (automated and customized)

We revive your legacy applications created on the basis of retiring languages and platforms (such as PowerBuilder, Delphi, VB, C++, COBOL) or aging technologies (outdated Java and .NET versions) with the use of modern programming languages, frameworks and databases.

Application rearchitecting

We transform the architecture of the application (e.g., split it into web services/microsevices) to make it leverage cloud possibilities to the fullest. The application will adapt to dynamic load and performance requirements, allow for partial updates, technology mix, and shared platform usage.

Application containerization

Across all application modernization options, we can pack your apps into containers to isolate them at the OS level. This allows for:

Easy scalability.

Efficient memory usage.

Simplified movement from one application environment to another.

Quick deployment and configurations.

Implementation of CI and CD practices.

Modernization Challenges We Solve

No actual or detailed documentation (functional specification)

To smoothly substitute the legacy application, we mine business rules from existing application code and documentation, investigate code dependencies and component integrations. We readily cooperate with IT departments and other employees as well as third-party vendors, customer's partners, and other people knowledgeable of the application work.

Difficulty to predict modernization results

Qrapp’s training apps offer interactive simulation of work processes and guide a user through work flow operations (product assembly, medical procedures, product installation, etc.) with navigations and tips. Such AR apps can support on-the-job education in different spheres, including manufacturing, construction, public services, healthcare, and telecoms.To keep the modernization process manageable, traceable and visible we split the application into several independent modules to introduce changes fast and incrementally. Also, we recognize the critical role of risk management and implement thorough analysis of the enterprise app basing on technical, business and economic considerations.

Operational downtime

We ensure thorough testing coverage and broad monitoring to make sure modernized applications run as expected and don’t disrupt your business processes.

An application’s long freeze up

We can split the application into independent loosely coupled parts (e.g., microservices) for independent updates.

Revitalize Your Apps for a New Business Reality

We can help to boost the efficiency and agility of your applications.
