## AI overview

Shopify's Production Engineering teams prepare the platform for Black Friday and Cyber Monday by maintaining reliability and scalability for heavy traffic and sales volumes. Their preparations include game days that use controlled fault injection, artificial latency, dependency degradation, and fallback verification, along with synthetic load testing to evaluate applications and system components under expected demand.

## Source excerpt

Making commerce better for everyone is a challenge we face on a daily basis. For our Production Engineering team, it means ensuring that our 600,000+ merchants have a reliable and scalable platform to support their business needs. We need to be able to support everything our merchants throw at us--including the influx of holiday traffic during Black Friday and Cyber Monday (BFCM). All of this needs to happen without an interruption in service.
