Compare sovereign cloud offerings before a regulated workload moves

For CIOs, CISOs and cloud leads in regulated sectors deciding between hyperscaler sovereign regions, SI-run sovereign stacks and national clouds.

Engagement type: Team Pod
Experts: 3 consulted · 1 lead
Hours: ~45
Duration: 3 weeks

What the client needed

A regulated organisation needed to understand the sovereign cloud market before choosing a path: who buys sovereign cloud and why, how data residency, access controls, encryption and local frameworks such as GDPR and BSI shape the design and its trade-offs on scale and cost, and how hyperscaler sovereign offerings differ in practice from system-integrator stacks and fully national clouds.
