Every November, the same story plays out. A Magento 2 store that comfortably handles 200 concurrent visitors suddenly gets 5,000. The database connection pool exhausts. Varnish cache miss rates spike because products are being updated mid-sale. The checkout times out. The payment gateway returns 502s. And by the time the engineering team rolls back the promotion, the brand has lost six figures in revenue and a significant chunk of customer trust.
Peak events — Black Friday, Cyber Monday, flash sales, product launches, viral campaigns — don't just test your infrastructure. They expose every shortcut, every unoptimized query, every misconfigured cache, and every missing monitor you've been getting away with during normal traffic.
In this post, I'll walk you through a structured preparation plan that starts 8-12 weeks before your peak event and covers infrastructure, caching, database, queues, monitoring, and incident response.
