In 2018, Amazon lost over $100M in sales when it crashed on Prime Day. What went wrong… and how will Amazon scale for high demand during Prime Day 2024? 👇 When an e-commerce giant the size of Amazon experiences any amount of downtime, the impact on revenue can be severe. When that downtime happens to occur on Prime Day, the consequences would be catastrophic. Back in 2018, that’s exactly what happened. The outage lasted for several hours. The main Amazon website and mobile app were affected, with users reporting issues accessing product pages, completing purchases, and loading the home page. According to estimates, Amazon lost $100 million in sales during the downtime — an estimated $1.2 million per minute. There are a few key factors that likely contributed to the failure: 1️⃣ 𝐇𝐢𝐠𝐡𝐞𝐫-𝐭𝐡𝐚𝐧-𝐞𝐱𝐩𝐞𝐜𝐭𝐞𝐝 𝐭𝐫𝐚𝐟𝐟𝐢𝐜 𝐬𝐩𝐢𝐤𝐞 This exceeded Amazon’s capacity — despite its preparation. To mitigate these issues in real-time, Amazon attempted to fall back to a simpler frontend page, while blocking international traffic. 2️⃣ 𝐂𝐚𝐬𝐜𝐚𝐝𝐢𝐧𝐠 𝐟𝐚𝐢𝐥𝐮𝐫𝐞𝐬 Though Amazon used a robust microservices architecture, it likely faced issues where service dependencies caused cascaded failures. This was also reported for other Amazon services, such as Twitch, Alexa, and Prime Now. 3️⃣ 𝐃𝐞𝐥𝐚𝐲𝐬 𝐢𝐧 𝐬𝐜𝐚𝐥𝐢𝐧𝐠 While Amazon uses autoscaling to handle surges in traffic, there were delays in scaling up resources due to configuration issues with Amazon’s systems and services. This forced Amazon to manually deploy servers to meet the traffic load, which cost time and money. The surge in traffic was likely the biggest culprit — the system received approximately 63.5 million requests per second(!) on its storage and computational service. 📦 Amazon is a great case study in what it truly takes to scale for traffic during high-demand periods.
