"AWS's new networking philosophy focuses on making network connectivity nearly invisible to users and administrators alike. For AWS, networking needs to be as reliable as flipping a switch—it simply works, and no one notices unless it fails. To meet this goal, AWS spent the past decade moving away from traditional, proprietary network hardware and has built a unified, custom stack that spans everything from silicon to software."
"At the heart of this innovation is the decision to use a single switching application-specific integrated circuit (ASIC)—the silicon “brain” at the center of every network switch—across its aggregation, core, and border networks. Rather than the old industry practice of mixing and matching hardware from various vendors (each with its own firmware, bugs, and scaling challenges), AWS has network engineering and operations teams focus on a single, consistent foundation."
"This not only simplifies procurement and troubleshooting but also enables scalable, reproducible deployments that surpass the speed of conventional enterprise or cloud architectures. All these switches run NetOS, a Linux-based operating system that AWS built to optimize security, automation, and r"
AWS is upgrading its end-to-end custom networking stack to make connectivity nearly invisible to users and administrators. The platform aims for reliability comparable to flipping a switch, with fewer operational surprises. AWS built a unified approach that replaces mixed vendor hardware with a consistent foundation across aggregation, core, and border networks. A single switching ASIC is used throughout the network, enabling scalable and reproducible deployments. The switches run NetOS, a Linux-based operating system designed for security and automation. These changes are positioned to improve performance for next-generation workloads such as generative AI and globally distributed applications, while enterprises must plan strategically to capture the cost and operational advantages.
