Technology has a limited shelf life. CPU processing power doubles every four years, and data volumes increased by 32X in the last decade. Yet many businesses still rely on software built in the pre-cloud, pre-AI era, facing high costs and limited scalability. Intellias helps businesses achieve peak performance with application modernization services – shaped by AI, informed by data, and driven by outcomes.

FAQs about our application modernization services
Legacy applications pose security, operational and growth risks. They may lead to compliance, regulatory, data loss and performance issues, causing operational disruptions. Because of limited scalability, legacy technologies also reduce your capacity to innovate and expand your market presence.
To determine the optimal approach to application modernization, our consultants perform technical debt and cloud readiness assessments. In practice, this means that we map your entire technology portfolio to understand an app’s logic, dependencies and constraints. Then we suggest the most economically viable and risk-free approach to modernization.
We conduct a holistic assessment to map technical debt on three levels: 1) code; 2) production and architecture; and 3) impact on product scalability, performance, TCO and user experience. Then we look into all instances to formalize a tech debt repayment plan, which combines quick wins with incremental wide-scale modernization.
As part of our assessments, we identify the main security vulnerabilities in individual applications and your IT estate to provide you with a clear overview of prioritized risks. Afterwards, we integrate modern authentication, data encryption, compliance and cybersecurity measures as we modernize your applications.
