AWS’s CLOUD Act defense inadvertently reveals they can access customer data when technically feasible. Despite sovereignty agreements, 20,000+ surveillance requests and academic research show “sovereign” clouds offer limited protection, making platform-independent modernization essential for regulatory flexibility and business resilience.
The CLOUD Act prevents US cloud providers from guaranteeing European data sovereignty, as Microsoft’s Carniaux recently admitted regarding French citizen data. This regulatory complexity highlights why mainframe modernization strategies need platform-agnostic deployment capabilities rather than single-vendor lock-in solutions.
European organizations need data sovereignty and mainframe modernization, but platform-dependent solutions prevent migration to sovereign clouds. Heirloom’s proven mainframe application modernization technology enables rapid, low-risk deployment to every platform including sovereign platforms like STACKIT, OVHcloud & Tietoevry, achieving compliance and cost reduction.
