Nordic telecom operator scaling B2B services and modernizing legacy infrastructure

Telecommunications SOLNA, - 10,001+ employees Public Company

Telia operates a major regional telecom network across the Nordics and Baltics, serving millions of customers with connectivity, IT services, and streaming (Telia Play). The tech stack reveals a transitional infrastructure: Oracle and PostgreSQL dominate data layers, Cisco and Fortinet secure the network, and Kafka powers streaming—but the company is actively replacing COBOL and adopting NSX-T and modern Java frameworks (Jetpack Compose, Firebase), signaling a shift toward cloud-native architectures.
