Having VMware in 2026 is a sign of low tech.
OpenShift is okay but has quirks unless you have a major Kubernetes staff; Proxmox is good for most but I wouldn't use at massive scale. Azure Stack/ Hyper-V can work but has its own quirks.
Tesco worked closely with a data startup to create the Clubcard and that startup is now a big company owned by Tesco (Dunnhumby, £350m, 2,000 employees)
They were the first supermarket to do online grocery delivery
They had Nokia apps for groceries on 2009, iPhone in 2010
Huge supply chain automation
Tesco Labs etc
It takes a long time to change corporate mindset.
