Stripe, a leading fintech company, leveraged Vercel to build and optimize a live look at their reliability during Black Friday and Cyber Monday. By harnessing Vercel's framework-defined infrastructure, Stripe was able to focus on design, performance, and reliability rather than architecting a dynamic cache system from scratch in 19 days. The team utilized Next.js, SWR, and ISR to create a flawlessly performing microsite that showcased real-time transaction data. To optimize for the unique challenges of a viral real-time microsite, Stripe implemented a solution that included getStaticProps, Stale-While-Revalidate, and Incremental Static Regeneration. This approach effectively decreased backend load by redirecting traffic to Vercel's cache network and utilizing ISR for background data generation. The project ensured reliability and uncompromising safety, with Stripe handling a peak volume of 93,304 transactions per minute while maintaining API uptime greater than 99.999%.
