Case Study: William Hill achieves faster time-to-market and 20% IT time savings with VMware NSX-T and vSAN

Transforming efficiency, scalability and agility with private cloud

William Hill, a leading global gaming company with an online platform handling millions of transactions daily, needed to speed time-to-market, reduce manual deployment tasks, and scale quickly for major sporting events while keeping costs and data locality under control. Its legacy blade-and-array infrastructure was slowing developers and operations, making it hard to roll out dozens of product changes each month and to scale instantly for peak demand.

William Hill migrated to an on‑prem Software‑Defined Data Center using VMware NSX‑T and vSAN HCI, moving about 5,500 VMs in a single eight‑hour window. The change cut provisioning from weeks to hours, saved developers and engineers ~20–25% of their time, delivered faster scaling for major events (5–6x normal load), reduced storage procurement costs, and accelerated product rollouts—improving agility and competitiveness.
