Lucknow Origin: DNS, Latency, and a CDN in Front
Point DNS at your Lucknow DC01 origin, measure real RTT, then put a CDN in front so global GETs cache at the edge while writes still hit Lucknow.

Cost-Aware Architecture on INR Pay-as-You-Go
Treat each VPS as a line item in INR: right-size roles, delay splits until SLOs demand them, and turn idle nodes off instead of overbuying reserved capacity.

Shared-Nothing vs One-Box Monolith Decision Tree
Walk a practical decision tree: keep the monolith on one VPS until a named bottleneck, then split one concern instead of copying the whole stack.
