Karnataka State Data Centre: Sharing Common Infrastructure

M N Vidyashankar
Principal Secretary, e-Governance Department, Government of Karnataka


The State Data Centre of Government of Karnataka was set up during 2004-05 as a core common technology infrastructure. The State Data Centre (SDC) provides the infrastructure required for consolidating state level applications at a central facility.

The State Data Centre is hosted in a physically secure Data Centre located centrally at Reliance IDC, Khanija Bhavan, Bangalore. It is continuously monitored by surveillance mechanisms and administered by 24×7 operations and management staff.

SDC connects to the remote Taluka servers through a VSAT network. SDC also has dedicated fibre connectivity to the Treasury network and to the State Secretariat. Connectivity to the web is through a shared 100 Mbps line.

Karnataka State Wide Area Network (KSWAN) would be shortly commissioned to connect SDC to all the Taluks, which would phase out the existing VSAT connectivity.
