Tech moves fast — so should you

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.

Clear outcomes: Our clients’ stories

Home improvement retailer

As eCommerce was taking off, a UK building supplies retailer was held back by a decades-old IBM UniVerse Mainframe core. To say that it was dead weight would be a major understatement. Intellias helped the retailer set a new trajectory for growth with a cloud-native platform, uniting front- and back-office operations.

  • More than 300 workloads migrated to the cloud environment to power better data exchange, ensure application scalability and support new digital channels
  • 99.999% cloud system availability achieved on top of 91% availability of the UniVerse mainframe, which has been kept for low-priority components
  • 30% reduction in infrastructure costs and 50% lower maintenance costs after migrating to a microservices architecture
  • Zero-downtime deployments for new products, system updates and bug fixes, resulting in a better customer experience
  • Innovative products launched for mobile commerce, digital order management and returns processing, generating 40% revenue growth

German telecom provider

For a German telco, legacy app migration to the cloud was a critical step for staying competitive and profitable. To accelerate new product development and deployment cycles, improve the customer experience and gain extra operating efficiencies, the company partnered with Intellias for BSS layer transformation.

  • More than 60 billing systems were re-architected as microservices and migrated to a multi-cloud environment.
  • 80% of mission-critical applications run in the cloud, allowing for instant scalability and better load balancing.
  • Infrastructure costs were reduced by 30% within three years thanks to optimized system design and new billing dynamics.
  • Enhanced compliance: all business processes, data models and APIs were standardized according to TM Forum ODA principles.

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.
