How CELESDEV designed an Azure enterprise landing zone, implemented autonomous subscription vending, and migrated 80+ workloads from on-premises data centres over 14 months — achieving a 40% reduction in infrastructure costs post-migration.
The client operated two ageing data centres with a contractual exit deadline 18 months away. 80+ workloads needed to be assessed, re-platformed, and migrated before the data centre leases expired. Previous cloud adoption attempts had stalled at the landing zone design stage due to conflicting security and network requirements between business units.
The core problem was not technical — it was governance. Six business units had different data classification policies, three security teams had conflicting interpretations of the group's cloud security baseline, and there was no central authority to resolve the conflicts. Every landing zone decision required a committee.
