TCS and DNA forge five-year strategic partnership to drive cloud transformation

Tata Consultancy Services, a global provider in IT services, consulting, and business solutions, has announced a five-year partnership with DNA, one of Finland’s leading telecommunications providers, to accelerate its cloud transformation programme.

Under the agreement, TCS will lead the migration of up to 80% of DNA’s enterprise applications to the public cloud by 2030. Building on a successful 17-year collaboration between the two organisations, this partnership aims to enhance customer experience, improve operational efficiency, and drive significant cost optimisation.

Jussi Tolvanen, CEO of DNA , commented,“Cloud adoption is essential for DNA's business, as we serve millions of customers and manage vast volumes of data. Running AI services without a cloud-based data platform is virtually impossible. Working with a skilled and experienced partner enables us to optimise costs, increase agility, and deliver superior service quality. Our aim is to remain at the forefront of connectivity for our customers.”

As part of DNA’s broader ‘Journey to the Cloud’ initiative, TCS will utilise its proprietary tools, TCS CloudCounsel and TCS Migration Factory on Google Cloud, to streamline and automate key migration processes. In the initial phase of the programme, more than 100 applications will be migrated to Google Cloud over the next 24 months. To support this at scale, TCS will establish a dedicated Cloud Migration Factory at its nearshore delivery centre in Portugal, ensuring efficient management of application migration and modernisation.

Sari Leppänen, CTO of DNA Plc, stated,“Having a strong strategic partner with us to lead this transformation journey is critical to success. By leveraging TCS CloudCounsel and TCS Migration Factory on Google Cloud, we are well-positioned to lead the cloud transformation of Finland’s telecom sector. This transformation brings new levels of speed, innovation, operational flexibility, and long-term efficiency.”

Thomas Skjelbred, Head of Global Procurement at Telenor Group and CEO of Telenor Procurement Company, said,“Telenor Procurement Company’s goal is to create lasting value through efficiency and expertise. We are pleased to recognise TCS as a trusted and capable partner in DNA’s Cloud Migration and Modernisation project, an initiative central to our long-term digital transformation strategy. This collaboration already demonstrates strong alignment with our objectives, and we are confident it will support future growth and innovation.”
