Got questions about application modernization?

What is Application Modernization?

Application modernization is the process of updating legacy applications—including architecture, infrastructure, and code—to adopt modern technologies such as cloud computing, microservices, containers, and DevOps, improving scalability, performance, and maintainability.

‍

Why is application modernization important?

Modernizing your applications helps to:
‍

  • Reduce technical debt and maintenance costs
  • Improve performance, security, and scalability
  • Enable cloud-native features and automation
  • Deliver better user experiences
  • Accelerate innovation and time to market

‍

Who needs Application Modernization Services?

  • Enterprises with aging legacy systems (monoliths, on-prem apps)
  • Companies migrating to the cloud
  • SaaS vendors upgrading to multi-tenant or microservice models
  • Regulated industries needing compliant, scalable platforms
  • Startups acquiring legacy codebases or apps

What services are included in your Application Modernization offering?

  • Legacy code and architecture assessment
  • Cloud migration and replatforming
  • Containerization (Docker, Kubernetes)
  • Microservices decomposition and API enablement
  • UI/UX redesign and frontend modernization
  • DevOps and CI/CD pipeline implementation
  • Security and compliance upgrades

What modernization strategies do you support?

We support all major strategies:
‍

  • Rehosting (lift and shift)
  • Replatforming
  • Refactoring / rearchitecting
  • Rebuilding or replacing with new applications
  • Hybrid approaches combining legacy and modern services

Which platforms and technologies do you support?

  • Cloud: AWS, Azure, Google Cloud, DigitalOcean
  • Languages/Frameworks: Java, .NET, Node.js, Python, PHP, Ruby, Go
  • Containers: Docker, Kubernetes, OpenShift
  • Databases: PostgreSQL, MySQL, MongoDB, Oracle, SQL Server
  • Monitoring: Prometheus, Grafana, Datadog, New Relic

Will modernized apps integrate with my current systems?

Yes. We ensure backward compatibility and seamless integration with your existing databases, APIs, and services, and support hybrid architectures during transition phases.

Can modernization improve application performance?

Absolutely. Performance improvements include:
‍

  • Faster load and response times
  • Scalable workloads with auto-scaling and resource optimization
  • Reduced downtime through high availability architecture

How do you address security in modernization?

We apply modern security practices such as:
‍

  • Identity & access management (IAM)
  • Code scanning and automated vulnerability detection
  • Data encryption in transit and at rest
  • Compliance-focused logging and monitoring

Can you customize the modernization plan for our specific goals?

Yes. We develop tailored modernization roadmaps based on your business objectives, tech stack, regulatory environment, and operational needs.

What kind of support do you offer post-modernization?

We provide:
‍

  • Ongoing maintenance and optimization
  • Performance monitoring and incident response
