T-Systems Austria Tech Stack

SAP infrastructure and integration services for enterprise customers

Information Technology & Services Wien 501–1,000 employees Public Company

T-Systems Austria operates enterprise ICT infrastructure for large corporations and public institutions, with heavy focus on SAP modernization—particularly S/4HANA migrations and HCM implementations. The tech stack reveals deep SAP ecosystem entrenchment (S/4HANA, SuccessFactors, BW/4HANA, BTP) paired with cloud adoption (AWS, Azure) and data platforms (Databricks, dbt, Fabric), signaling a shift from on-premise legacy systems toward hybrid cloud SAP deployments. Project velocity centers on S/4 conversions, legacy system replacement, and integration complexity—not greenfield product work.
