'''Video summary:''' Architecture walkthrough of the West Bengal "OBPASS" (online building-plan approval) government application. Staging is a simple single proxy/single app/single DB server chain. Production is more redundant: two proxy servers behind a load balancer, two application servers (one handling the bulk of traffic, the second more of a standby that can't fully absorb the load alone if the first goes down), and two database servers in a manual master/slave setup (failover to the slave is not automatic -- has to be brought up by hand). A separate Windows "scrutiny" server, connected to both staging and production, receives files pushed from the application during the citizen-facing form-submission flow. Shared document/PDF storage is an NFS mount, synced from the primary to secondary app server by a script whenever a developer changes data. Covers a recent migration of the whole 7-server production estate onto the state government's own "SCI platform" data center (new floating IPs for every server), with the NFS disk's actual mount-point cutover still pending (scheduled for a maintenance window later that night) and a related planned hardware upgrade (RAM/disk) once the state data center processes the request. Briefly mentions NKDA as a related project on the same platform, with its staging server ready but production not yet built.
