Frequently Asked Questions
Legacy application modernization is the process of updating older software systems, applications, and platforms to newer, more efficient, and scalable technologies. This often involves migrating them to the cloud, re-architecting them from a monolithic to a microservices-based structure, and adopting modern DevOps practices. The goal is to reduce maintenance costs, improve performance and security, and enable new business capabilities like AI and data analytics.
We prioritize minimizing disruption through a proven, phased migration strategy. Our CMMI Level 5 certified process includes comprehensive planning, parallel run environments, robust data synchronization, and automated testing. We often employ patterns like the 'Strangler Fig' to incrementally replace legacy functionality with new services, ensuring the core business operations remain unaffected throughout the transition.
The 'best' platform depends entirely on your specific needs, existing technology stack, budget, and long-term goals. We are multi-cloud experts and conduct a thorough Cloud Readiness Assessment to provide an unbiased recommendation. We analyze factors like your current licensing (e.g., Microsoft licenses often favor Azure), your industry's data gravity, and your desired services (e.g., AI/ML strengths in GCP) to architect the optimal solution for you.
While it varies, clients typically see a significant ROI within 18-36 months. The returns come from multiple areas: a 30-50% reduction in Total Cost of Ownership (TCO) by eliminating expensive legacy hardware and licensing, improved developer productivity, faster time-to-market for new features, and enhanced business agility. We can help you build a detailed business case during our initial assessment.
Security is paramount. As a SOC 2 and ISO 27001 certified company, we embed security into every stage of the process (DevSecOps). This includes end-to-end encryption for data in transit and at rest, robust identity and access management (IAM) controls, and building infrastructure that meets industry-specific compliance standards like HIPAA, PCI DSS, and GDPR. We conduct regular penetration testing and vulnerability assessments to ensure your new environment is secure from day one.
Absolutely. This is a very common challenge. We use AI-powered code analysis and reverse engineering tools to automatically map dependencies, understand business logic, and create the necessary documentation. Our experienced architects are skilled at deciphering complex, undocumented systems to build a safe and effective modernization roadmap.
