e-WAY BILL : One Nation – One Tax – One Market – One e-Way Bill
The e-Way Bill System is a document which gives details regarding the movement of goods and has to be carried by transporters for any consignment exceeding Rs 50,000. The complete e-Way Bill System, which includes development of web-based IT Application, hosting IT infrastructure (which includes network, computing and security) and operation & management of the system is the responsibility of National Informatics Centre (NIC).
It provides multiple modes of e-way Bill generation including Web, Bulk Upload, SMS, Mobile App and API for Large Taxpayers/ GST Suvidha Providers (GSPs).
As 24×7 accessibility is a critical requirement of this application, infrastructure is designed to provide redundancy at multiple levels including firewall, load balancer, switches, racks, virtual machines (web servers), database servers and MPLS links (for connecting to GSTN servers). Virtual machines for webservers are created on Hyper-V clusters. 24 VMs are used as front-end (with IIS). Number of other VMs have been created for API, Mobile App, GSTN API and Redis.
Two Availability Groups of four Database Servers, each are configured to ensure redundancy at the Database level. In each Availability Group, out of four Database Servers, two servers store data of two zones each and sync copies of two other zones whereas the other two servers are async copies of the data of four zones used for reporting purposes.
The third availability group has two database servers which store session and authentication databases respectively.
Considering criticality of the application, 24×7 Help Desk is set up at NIC Centre, Koramangla, Banglore to provide L2 support to the issues forwarded by the GSTN Help Desk. The Help Desk functions 24×7 which enables quick resolution of the issues and closing of tickets forwarded by GSTN Help Desk.
The application performance is also monitored round the clock. PRTG is configured to monitor the health of the infrastructure i.e. Web VMs, Database Servers, Firewalls etc. The parameters monitored include utilization of processor and memory, ping, HTTP response time etc. Additionally, a Dashboard is also provided to display State-wise/ Zone-wise e-Way Bills generated in every five minutes. These tools and mechanisms facilitate the team to identify any system or service outage within no time and respond quickly.
