Presentation Transcript

  1. State e-governance Service Delivery Gateway(SSDG)‏ A Messaging Middleware for Integration & Interoperability

  2. Agenda • Need of Gateway • What is SSDG? • Benefits of SSDG • SSDG Architecture • Role of Connectors • Service Level of SSDG • SSDG Support • Roles & Responsibilities

  3. Current Set-up • Low or no data exchange between various departments • Computerization without interoperability • If automated various departments may use different technologies, platforms, languages for developing their applications which may become a limiting factor in data exchange between departments • Data exchange in paper format • Each department has a separate front-end • Citizen needs to visit and remember multiple locations for their various requests. • No unified face of government

  4. Department 2 Department 1 Front-end 1 Department 3 Front-end 2 Department 4 Department 6 Department 5 Without Gateway

  5. PWD RTO Land Records Standards Based Communication Standards Based Communication CSC/ State Portal SSDG Standards Based Communication Standards Based Communication TAX Standards Based Communication Election Commission Municipal Services With SSDG (Example Scenario)‏

  6. What Is SSDG? • SSDG is a message X-change • Interoperable – • Helps any Service Access Provider (SAP) to Communicate with any Service Provider (SP) with appropriate authentication • IIP/IIS standards are developed to achieve this • XML based data • Secure • Authentication between SAP and services is achieved through mapping • PKI support • XML signature

  7. Cont… • 24 X 7 availability • Decouples front end from the business logic • Useful for joint services • No vendor locking

  8. Who Will Benefit from SSDG? • Government Departments • Service Access Providers (Citizen Service Centre)‏ • Citizens

  9. Government Departments • Multiple delivery channels • Better audit management & time stamping • Web enabling of legacy applications • Interoperability • Departmental workflow • Seamless availability of information • Centralized management • Shared services

  10. Citizens • Status tracking • Grievance re-addressing at one point • Data privacy maintained • Single window service catering to multiple departments • Allows the citizen to fill minimum data and fetches already available data under Unique ID from other departments • Quick response to end user • Keeps a record of each transaction in a secure manner and does not open the packet data (payload)‏

  11. Service Access Providers • Easy interface with departmental data & business logic • Integrated and joined up services • Flexibility in modifying the front-end application without touching the back-end applications

  12. SSDG Solution Service Access Providers (SAP) or Service providers (SP)‏ Implemented by IA Applications Connectors SSDG SSDG Stack Consultancy to Implementation Agencies provided by C-DAC C-DAC Support

  13. Framework Continues • End To End Integration

  14. Connectors • Designed for easy programming interface • Facilitate easy integration with SSDG • Ensure compliance to IIP (Interoperability Interface Protocol) and IIS (Interoperability Interface Specifications) messaging standards available in Java and .NET used by SSDG • Two types of connectors • Generic Connectors • Application Specific Connectors

  15. Connectors • SAP Connectors • Generic Connectors • Application Specific Connectors • SP Connectors • Generic Connectors • Application Specific Connectors

  16. Working with Connectors

  17. Application Specific -SAP • Request from SAP to avail SP service will be sent through SSDG. • Application Specific Connector will take the data from SAP and will convert the request as per the format understood by SP. • Application specific Connector will use the API’s of Generic Connector to send the payload as per the IIP/IIS standards to the SSDG. • Application Specific Connector will be developed by IAs.

  18. Generic -SAP • Purpose of generic connector is to interface with gateway for standards based messaging communication. • C-DAC will be providing Generic Connectors. • Generic connectors are available in Java,. NET and php.

  19. Generic -SP • Purpose of generic connector is to check whether the message sent by SSDG is valid or not. • If the message sent is valid ,it passes the message to Application Specific Connector by extracting the payload and other necessary details. • If the message is invalid then it sends back the message to SSDG by populating necessary error codes. • C-DAC will be providing Generic Connectors. • Generic connectors are available in Java,. NET.

  20. Application Specific -SP • Based on the payload and details provide by generic connector, application specific connectors will send the request to SPs whose services are requested. • Application specific connector will send back the necessary response to SAP through SSDG. • Application Specific Connector will be developed by IAs.

  21. SSDG Message Exchange Synchronous Communication SAP (portal) Gateway SP( Back off ) Synchronous Submit Request Synchronous Submit Request Synchronous Response Synchronous Response

  22. Asynchronous Communication SAP (portal) Gateway SP( Back off ) Asynchronous Submit Request Submit ACK Asynchronous Submit Request Submit ACK Submit poll Submit ACK Submit Response Submit ACK Submit poll RESPONSE

  23. Service Level of SSDG • Supports 50/100/250 messages per second (based on the BOM purchased by State) • 95% of the transactions will a response time of 3 seconds else it will constitute a violation.(Note: Performance may vary depending on the Hardware Components used.)

  24. Roles and Responsibilities of C-DAC • C-DAC will provide SSDG software product • C-DAC will also provide the optimized SSDG software stack containing: • Operating System • Application Server • RDBMS

  25. Roles and Responsibilities of C-DAC • C-DAC will provide necessary patches, service packs and upgrades of SSDG over a period of 1+3 years • C-DAC will provide technical support for SSDG product and the optimized Stack • C-DAC will provide the training to the Implementation Agency (IA) and the state personnel.

  26. Roles and Responsibilities of State • State needs to sign an End User Licensing Agreement (EULA) with C-DAC before deploying the SSDG product. • It is recommended to get the deployed SSDG solution certified by STQC as per ISO 20000 and 27001 standards. • States should purchase the hardware subject to compliance with the Bill of Material (BOM) provided by C-DAC.
