How Walmart Drives Operational Excellence with Open Source Innovation
Walmart runs a massive network over 5 million connected devices across 10,500+ stores, fulfillment, and distribution centers. Managing such scale with diverse vendor systems is complex and costly. To simplify, Walmart embraced open-source platforms like SONiC (a Linux-based network OS) and L3AF (an eBPF orchestration and observability tool). These solutions allow the use of standardized, white-box hardware managed under one common OS, ensuring consistent performance, simplified automation, and improved reliability.
By contributing to and working with open-source communities, Walmart reduces vendor lock-in, streamlines codebases, and eases cognitive load for engineers. This lowers operational costs (reflecting their everyday low-cost ethos) and boosts network stability, while also enabling innovation at scale. As a result, Walmart can roll out network improvements faster across thousands of sites delivering strong ROI and continued growth in its digital infrastructure.
