Target wanted deploying to a store to feel the same as deploying to the cloud or its data centers. It put Kubernetes in every store and built Unimatrix, a central system that captures an application's intended state and distributes it to the store clusters. What that design solves, and when a retailer needs it.
Target set a goal that the development and delivery experience should be the same whether a team deployed to the public cloud, Target's data centers or its roughly 1,800 stores.
It chose Kubernetes as the common foundation and ran a cluster in each store.
It built Unimatrix, a central system that is the single interface for deploying to stores. It records an application's intended state and distributes that state to the store clusters, so a team can change the whole fleet with one command.

The insight is organizational, not technical: if store deployments are different and harder, teams avoid shipping to stores, and in-store software falls behind online.
Central intent, local execution is the same pattern Chick-fil-A reached with GitOps. Each site converges on a declared state and keeps working when disconnected.
This is a large-retailer solution. With dozens of locations rather than thousands, a managed edge option (EKS Hybrid Nodes, IoT Greengrass) or a well-built device image is less to own.

Computing in the Store: What Chick-fil-A, Walmart and McDonald's Built at the Edge
Chick-fil-A runs a Kubernetes cluster in every restaurant, managed by GitOps. Walmart runs regional clouds plus edge clouds in stores and clubs. McDonald's is putting Google Distributed Cloud into thousands of restaurants. Why retailers put compute in stores, how they manage thousands of tiny sites, and the AWS equivalents.

How Lowe's Replaced Its E-Commerce Platform: Carbon, Kubernetes and Deploys in Hours, Not Weeks
Lowe's left a packaged, monolithic e-commerce system from late 2018, invested more than $500 million a year and hired up to 2,000 engineers. Its internal platform, Carbon, now runs more than 1,000 workloads across cloud, data center and stores, and carried 111% e-commerce growth in 2020. What they built and how it compares with Home Depot's path.
