Executive Summary

ANALYST: COI RESEARCH

To comply with strict EU data export rulings (Schrems II), the bank adopted a Sovereign Cloud strategy. This architecture ensures that key encryption keys are managed within the EU by a trusted third party (T-Systems), preventing the US cloud provider (Google) from accessing the data, thus satisfying regulatory requirements for data residency and immunity from foreign subpoenas.

rate_review Analyst Verdict

"The bleeding edge of policy-driven infrastructure. The 'sovereign cloud' is the only answer to the geopolitical splintering of the internet. It allows global banks to use hyperscale tech (Google/AWS) without legally 'exporting' the data."

warning The Challenge

EU regulators ruled that transferring personal data to US cloud providers violated GDPR because US surveillance laws (FISA 702) trumped EU privacy rights. The bank risked being unable to use public cloud for core systems.

psychology The Solution

The bank utilized Google's Sovereign Cloud offering. Data is encrypted at rest and in use. The encryption keys are held by a German custodian (T-Systems). Policy controls prevent any administrative access from outside the EU.
