Walmart tells some tech providers not to use Amazon Web Services if they want Walmart's business
Wal-Mart is telling some technology companies that if they want its business, they can't run applications for the retailer on Amazon's leading cloud-computing service, Amazon Web Services.
Context & Ripple Effects
Walmart is using its procurement weight as a weapon against its fiercest retail rival: technology vendors that want Walmart's business can't run the retailer's applications on AWS, the market-leading cloud. It is the mirror image of the cross-market leverage Amazon itself is accused of — the related coverage later details how Amazon compels vendors in one market to accept its terms in others, including threats of punitive action — with Walmart now playing the same card from the buy side.
The move kicks off a five-year arc of cloud de-risking at Walmart: a year later it signs a strategic partnership with Microsoft for cloud, AI, and machine learning, it extends the same leverage playbook to smart-home vendors by requiring Google Home compatibility, and by 2022 it reports its own hybrid cloud with 10,000 edge nodes cutting costs 10%-18% annually and lessening reliance on the cloud giants.
First-order effects
- Tech providers serving Walmart must re-architect or re-host applications off AWS or forfeit the retail relationship — an immediate revenue and engineering cost imposed on named vendors.
- AWS loses prospective retail workloads not on price or capability but on who its parent company is, a competitive exclusion unavailable to any rival except Walmart itself.
Second-order effects
- Microsoft is the structural beneficiary: Walmart's subsequent cloud partnership routes the displaced workloads to Azure, and by 2022 Microsoft is asking Google and Oracle to help push the US government to spread cloud spending — the same anti-AWS-concentration logic Walmart applied privately.
- Vendors caught between the two retailers face split infrastructure builds, raising costs that flow into pricing for retail technology contracts broadly.
Third-order effects
- If the pattern holds, hyperscaler selection becomes a bargaining chip in every large retailer's vendor negotiations, and customers with rival businesses to a cloud provider build hybrid or multi-cloud stacks — Walmart's edge-node buildout is the template — to cap their dependence on a competitor's infrastructure.
- The episode foreshadows the regulatory scrutiny of cross-market leverage that Amazon's own vendor practices later attracted, with buyer-side exclusion now documented as a standard tactic on both sides of the retail-cloud rivalry.
The trend: Large retailers are treating cloud provider choice as a competitive weapon, shifting workloads away from a rival's infrastructure and toward multi-cloud and owned edge capacity.
