Case Study: PayU India achieves two-week time-to-market and massive scale with Amazon Web Services

PayU India Reduced Time-to-Market to Two Weeks by Using AWS

PayU India, a top-three online payment gateway with more than 300,000 merchants and a rapidly growing consumer base, faced the challenge of consolidating systems after merging with Citrus Pay and scaling its infrastructure fourfold to support a new payment-consolidation and short-term credit product (LazyPay). The company needed a secure, low-latency, India-based platform that met PCI-DSS and data-residency requirements, could handle sudden transaction spikes (such as post-demonetization demand), and would let teams run fast proofs of concept to accelerate time-to-market.

PayU implemented its cloud architecture on AWS Asia‑Pacific (Mumbai), using VPC for tiered security, Auto Scaling, Amazon Redshift, AWS Lambda, and machine-learning tools to generate credit scores. The move let PayU scale from supporting ~10,000 to 300,000+ merchants and from 25M to 50M+ consumers, process about ₹60 billion/month, maintain a few-millisecond latency and 99.999% availability, handle demand surges, and bring LazyPay to production in roughly two weeks while meeting compliance and cost goals.
