CACI Ltd is delighted to announce it has been selected by Amazon Web Services (AWS) as an official launch partner for the AWS European Sovereign Cloud (ESC), a major AWS initiative designed to help organisations meet stringent European digital sovereignty, security, and compliance requirements.
This appointment further reinforces CACI – a global AWS Premier Tier Partner – as a trusted advisor for organisations looking to adopt sovereign cloud solutions while leveraging the scale, resilience and innovation of AWS.
The European Sovereign Cloud is purpose-built to ensure the highest levels of governance and assurance, making it particularly suited for mission-critical and highly regulated sectors such as public services, national security, defence, financial services, healthcare, and critical infrastructure. This is also essential in supporting large commercial organisations navigate regulatory landscapes, protect sensitive data, and maintain customer trust at scale.
Why are the AWS ESC Principles Important?
The AWS ESC applies the principles above in the European context, giving organisations absolute confidence that their data and operations remain under tight European control, while enabling innovation without compromise.
Key capabilities include:
- EU-only operations: managed exclusively by EU-based personnel, ensuring governance and operational independence.
- EU data residency: all customer data – including metadata – remains within the EU, supported by isolated service environments.
- Independent European infrastructure: physically EU-based facilities with separate control systems including independent billing, security, and multiple Availability Zones for resilience.

CACI brings proven expertise in cloud transformation, security, and compliance. Becoming an ESC launch partner further enables CACI to:
- Guide organisations through sovereign cloud adoption using AWS best practices.
