Application Modernization Services

Construct a Legacy Application Update Strategy without any Risk

Why Modernize? 

Older frameworks like Struts, JSP, and Java EE often lack vendor support and regular security updates. This makes applications more vulnerable to cyberattacks and non-compliant with modern security standards (like OWASP, GDPR, etc.).

Legacy systems often require:

  • More time and effort to maintain

  • Specialized skills that are harder to find

  • Higher costs for bug fixing and enhancements

Modern stacks like Spring Boot, Angular, or React are easier to maintain and have large active communities.

Legacy apps were built for monolithic architectures. They:

  • Don’t scale well with modern user loads

  • Have slower performance due to outdated processing models
    Modernized apps, built using microservices and cloud-native principles, scale more efficiently and handle high traffic with ease.

Legacy applications:

  • Are hard to update or extend

  • Slow down innovation cycles
    Modern technologies support Agile and DevOps practices, enabling faster development, continuous delivery, and faster time-to-market.

Legacy apps often use outdated protocols and are hard to integrate with:

  • Modern APIs

  • Cloud platforms

  • SaaS tools (like CRMs, ERPs, etc.)
    A modern tech stack with REST APIs and Spring Boot makes integration seamless

New developers are more familiar with:

  • Spring Boot, Angular, React, etc.

  • Cloud services (AWS, Azure)

  • Containerization (Docker, Kubernetes)
    Modernization helps future-proof your workforce and systems.

Our Process

Analyze and Set Priorities

We evaluate legacy apps based on two key criteria: their business value and the amount of technical debt they have accrued. The ones with the greatest value and lowest debts are given more priority. This method expedites the arrival of results and, by extension, the return on investment for any given effort.

1

Start Out Small

Almost every modernization project, in our experience, comes with its own set of technological, cultural, or operational difficulties. We've learned the ins and outs of the project by starting on a small scale. This allows us to simultaneously begin generating measurable success, which helps us secure the support of key stakeholders.

2

Split Large Applications into Smaller Microservices

Even when adhering to a domain-driven design process, assumptions must often be made when outlining the scope of a microservices-based strategy. At DifferenTech, we structure systems so that microservices have clear, definable boundaries within the larger monolith. We then gradually split the system into distinct microservices through testing, development, and observation.

3

Automate

Everything as Code refers to the practice of managing all aspects of your infrastructure through code. Adding automation to your company and applications isn't just about optimization; our engineers use it to provide vitality, agility, resilience, and security. This establishes a shared vocabulary across groups and prepares the way for more efficient feature development and refinement.
