This post details Shopify's preparations for Black Friday and Cyber Monday (BFCM), focusing on Production Engineering's role in ensuring platform reliability and scalability. It highlights the use of 'game days' for fault injection (e.g., introducing artificial latency to shipping provider interactions) and load testing to simulate peak traffic. The post also discusses the implementation of feature and code freezes to minimize changes during the critical period. The success of these preparations is evidenced by record-breaking sales and order volumes during BFCM 2018, reinforcing the value of proactive risk management and dependency testing.
