Case Study: LEGO achieves 50x more traffic resilience and scalable orders with commercetools

How LEGO put the building blocks in place to ensure website stability even during major traffic surges

LEGO, the global B2C toy maker, was struggling with reliability and scalability: the site crashed during major product launches and Black Friday peaks. To fix this, LEGO partnered with commercetools and moved to a cloud-native MACH commerce platform, reworking its architecture to gain control, resilience and the ability to auto-scale.

commercetools implemented a cloud commerce solution and modular MACH architecture across LEGO’s digital ecosystem, enabling auto-scaling, faster experimentation and low-cost R&D. The change produced measurable gains — a 7x increase in orders per second (from handling 7 to 35 orders/sec during peak launches) and the ability to absorb roughly 50× larger traffic peaks on Black Friday — while unlocking new channels and customized experiences.
