Imagine applying for PAN card via a common service centre. You complete all the formalities, and you get you PAN within the specified time. Have you ever wondered how all this is made possible, and what are the networks working to make this feasible? Behind all this is the infrastructure. The Service Delivery Gateway is part of this infrastructure.
For the delivery of various services under different e-governance projects, Service Delivery Gateway plays a significant role. e-Governance infrastructure comprises State Wide Area Network, State Data Center, Service Delivery Gateway, Common Service Centers and the GI Cloud (MeghRaj).
Service Delivery Gateway (NSDG) is the component of service delivery network – the basic e-Governance infrastructure involved in imparting the numerous public services delivered to the people by the government.
The Service Delivery Gateway (NSDG) comprises the three components of NSDG, SSDG, and MSDG.
The government functioning is made possible by diverse systems that use different technologies and platforms and different degrees of automation. All this makes the task of achieving the goal very challenging.
An MMP under National e-Governance Program, the NSDG has simplified the task by “acting as a standards-based messaging switch and providing seamless interoperability and exchange of data across.’’
E-governance service application for different departments for online services for citizens, businesses, and government entails growing interaction among departments and different levels of the government. The departments have to develop connectors/adaptors for point-to-point connections, leading to a complex mass of applications.
This makes the applications hard to maintain and undergo changes (upgrading) when needed and in accordance with changes in government policy or business rules. It is here that the role of NSDG becomes relevant. The National e-Governance Service Delivery Gateway (NSDG) seeks to reduce the multiplicity of point-to-point connections between departments and provide a standardized switch for interfacing, sending messages and routing switch to enable the various departments, front-end service access providers to make their data and applications interoperable.
The objectives of NSDG are enumerated as follows
- To play as core infrastructure to enable standards-based interoperability between various e-Government applications at different levels and at different locations.
- To develop gateway messaging standards and a government central gateway based on standards.
- To help build standards-based e-governance applications with the Gateway as the platform to achieve interoperability.
- To enable integration of services by Centre, State or Local governments.
- To help protect the infrastructure by integrating it with other platforms and software.
- To de-link the back-end departments/Service Providers from the front-end Service Access Providers to enable separation of service access, and to encourage competition.
- To enable the addition of shared service to the core services as and when required.
- To economize the cost of e-governance project.
- To ensure secure transactions using PKI infrastructure.
- To enable tracking of transactions and centralized control.
- To enable departments to evolve gradually as the Gateway as a middleware.
Given the massive size of networks, heterogeneity of applications and their usage across users at different levels within the government and without, ensuring high-quality service sustainably without affecting the quality of the service is a herculean task. The NSDG is the infrastructure that enables smooth functionality.
