Challenges in e-Governance
Architecture
• National E-Governance Plan Strategy
– Centralized initiative decentralizedimplementation
• Core common Policies, guidelines, standards,framework, infrastructure (federated architecture)
– A lot happening in this direction (standards, guidelines,
SWAN, CSCs, SDCs etc)
• Challenges in implementation of variousarchitectural components

Business Architecture challenges
- Identifying commonalities across states/ depts. to devisere-usable Services, processes, forms etc
• Multiple Players – Applying Enterprise Architecture (awareness, governance)
• Single Core software?
• Business Models (service based) – Multi-sourcing, single-sourcing
• Data & Application security and ownership – Policies, guidelines, controls need to be in place
• Service Level Agreements – Internal & External (Passport)
– Dependency on other MMPs
• Exit Management
• Synchronization & clear strategy for core componentinduction

Technology Architecture challenges
• Platform independent, scalable, Open Standards - Policy• Network & System Architecture
– Centralized/ Decentralized / hybrid• Connectivity, transaction volumes• varying timelines - interim solutions, a clear migration path to a future
centralized strategy
• Legacy applications / Backend maturity / location of existingdatabases• Service Access Architecture
– Multiple delivery channels (MMP portals, State portals, India portal, SCAportal etc)
• Single sign-on
• Localization/ multi-language support• Digitization of old records
– Scanning, error removal, validation – Bulk signing
• Digital Signature Management

Organization Architecture
challenges
• In-house departmental resources – Arch team – Tech team to control appl. & Data – Contractual skills – PM skills
• Quality in e-Gov – within departments
• Defining and implementing CMM like processes (BIS 15700 – servicedelivery)
– within MMPs• Quality assurance framework
• 3rd party certification

Gateway Benefits
• Standards based messaging and routing switch
– ensuring secure and guaranteed delivery of services between the frontend portals and the back end departments and between departments
• Simplify the view of the external world to the departments – It will de-link the backend departments from the front end service delivery
mechanisms like CSCs.
– A department will connect only once to the Gateway and transact withmultiple CSCs.
• Complete audit logs & time stamping of transactions
• Facilitate Departmental work flow evolve gradually – a server may be put up at the department for message exchange with
Gateway in absence of readily available infrastructure at the department.
• Gateway has the capability to add additional functionality to supportshared common services like Authentication, payment gatewayinterface, etc

National eGovernance Service Delivery Gateway
(NSDG) system- Messaging Middleware
• The Gateway is a – Core standards based messaging & routing middleware
– based on XML and SOAP
– envisaged as a cluster at the National level & SDCs
– has the intelligence to route each request coming from theCSCs or any other Front ends to the respective departmentalServer offering the service
– The response from the departmental servers will be returnedback to the SCA portal or the State Portal via the Gateway.
• As a part of this project, a National Service Directory(NSD) to resolve the address and service resolutionbetween the Gateways is also being set up
