Sovereign cloud disconnected in Luxembourg
In a world marked by many geopolitical tensions, digital sovereignty is an increasingly important issue. Businesses have strong needs and requirements when it comes to the cloud, they need to use innovative services, operated and supported by trusted providers, while maintaining control of their data.
The issue of data sovereignty is even more crucial for a European organization that is digitizing its operations and deploying the latest cloud innovations, as it wants to have full control over its data privacy while complying with European jurisdiction.
The sovereign cloud solves the dilemma between innovation and compliance. By combining the best of both worlds, it facilitates access to technological innovations while ensuring compliance and protection of sensitive data.
The solution we offer, based on Google Cloud technology, is a unique initiative in Luxembourg and in Europe
Based on Google Cloud technology , it enables customers to confidently deploy sensitive applications containing critical data and provide next-generation digital sovereignty controls.
Installed and managed locally, the solution offers all the necessary guarantees in terms of data preservation and constitutes the best compromise on the market between “strong sovereignty” and “access to the best of the cloud”. A pioneer in the European market, the platform is capable of offering an experience close to the public cloud in an environment completely isolated from third parties – including Google. Such a configuration allows full control of data location and access rights.
