Infrastructure

We deliver and operate infrastructure capabilities that are stable, secure, simple, and efficient, while scaled to support hundreds of thousands of team members and the experiences of millions of guests every day in one of the world’s largest retailers. We build and run cloud and compute platforms, network connectivity, data centers, field engineering, and big data systems that power our stores, digital, and supply chain experiences. Our software engineers develop distributed systems that run elastic compute across the hybrid cloud and the edge. Our hardware engineers operate IoT technology in stores, deploy wearables and robots in our supply chain, and integrate hardware in our data centers.

    Hardening the Registers: A Cascading Failure of Edge Induced Fault Tolerance

    June 22, 2022
    By John Engelman
    In 2017, Target announced that we had prioritized stores at the center of how we serve our guests – no matter how they choose to shop. To make this store-as-hubs model work, we spent several years redesigning operations and modernizing how we conduct business. We invested billions of dollars into remodeling stores, hardened our world-class supply chain, and created a robust suite of fulfillment options to meet every guest need.

    Triaging in Target’s Distributed Point of Sale Ecosystem

    June 9, 2022
    By Tyghe Vallard
    Across Target.com and nearly 2,000 stores, we run a complex and highly distributed point of sale (POS) ecosystem. And as we invest heavily in a great omnichannel POS experience, we continue to develop and scale new features for a variety of applications including store registers and self-checkout, our team members’ handheld myDevices, and our award-winning guest mobile app. As a result, we manage more software with a growing number of interactions – a single scan of an item during checkout could mean touching a distributed tree of dozens of services, with hundreds of thousands of these done per minute.
