The retail sector has experienced a significant shift towards online shopping, particularly during peak periods like Christmas, as consumers choose the convenience of online purchasing over traditional in-store visits. This change was evident when foot traffic decreased by 4.7% on Boxing Day, while online shopping surged, highlighting a transformation in consumer behavior. The UK experienced a notable instance of this shift during Black Friday in 2014, when many e-commerce platforms, such as John Lewis and Argos, struggled to handle the unexpected surge in online demand. Retailers are advised to rethink their capacity planning, which typically forecasts traffic a month in advance, to avoid performance issues that result in lost customers and revenue. By adopting a flexible and scalable infrastructure, retailers can better manage the fluctuating demand typical of festive periods, ensuring that their online platforms can handle increased traffic and maintain a seamless shopping experience.
