NSDG Goes Live on 14th August 2008!

The National e-Governance Service Delivery Gateway (NSDG) is one of the 27 Mission Mode Projects under the National e-Governance Plan (NEGP) of Government of India. The The National e-Governance Plan (NeGP) of the Govt. of India aims to cooperate, collaborate and integrate information across different departments in the Centre, States and Local Government.

The messaging middleware for integratrion and interoperability is executed by C-DAC Mumbai with support from the e-Governance division of the Department of Information Technology of the Government of India. NSDG will also be taken through its opeartion and maintenance phase by C-DAC for five years.

NSDG Go Live was inaugurated on August 14, 2008 by Shri Jainder Singh, Secretary(IT) in presence of renowned members of Department of Information Technology.

Government systems are characterized by islands of legacy systems using heterogeneous platforms and technologies and spread across diverse geographical locations, in varying state of automation, make this task very challenging. The emergence of many e-governance applications for different departments to provide online services to citizens, businesses and government would require increasing interactions amongst departments and with external agencies at various levels in Government. Departments would need to develop connectors/adaptors for point to point connections between departments creating a mesh as shown in figure and also tight coupling between applications. This would lead to applications difficult to maintain and upgrade in case of version change and change in government policies and business rules.

NSDG is an attempt to reduce such point to point connections between departments and provide a standardized interfacing, messaging and routing switch through which various players such as departments, front-end service access providers and back-end service providers can make their applications and data inter-operable using the framework of e-Governance Standards.

C-DAC has also successfully implemented National Services Directory (NSD) which needs to be utilized by all the gateways across the country. NSD provides a registry, which acts as a service resolution point for all the services in the Gateway constellation. All the Gateways that need to resolve services which are not in their domain, need to resolve it at the NSD. The services offered by the back-end government departments (Service Providers) will need to be uniquely identified and registered under the administrative domain of the concerned Gateway. The Gateway in reality becomes an aggregator of service information within its jurisdiction.
