<\/a>Run connected or fully disconnected. Sovereign Private Cloud unifies Azure Local, Microsoft 365 Local and Foundry Local, bringing modern infrastructure, productivity and support for large AI models to any operational boundary.<\/p>\nThis delivers a truly localized\u00a0full stack\u00a0experience\u00a0built\u00a0on Azure Local\u00a0infrastructure and Microsoft 365 Local workloads,\u00a0designed to stay resilient across any connectivity condition, with\u00a0large models\u00a0being part of\u00a0Foundry Local extending the stack to run advanced multimodal models locally, securely,\u00a0even when fully disconnected. Customers can\u00a0now\u00a0help\u00a0maintain uninterrupted operations,\u00a0keep\u00a0mission critical workloads\u00a0protected\u00a0and\u00a0apply consistent governance and policy enforcement,\u00a0while keeping data,\u00a0identities\u00a0and operations within their sovereign boundaries.<\/p>\n
Azure Local runs\u00a0critical infrastructure locally, even when disconnected\u00a0<\/p>\n
For workloads with specialized requirements, Azure Local provides the on-premises foundation with consistent Azure governance and policy controls.\u00a0With Azure Local disconnected operations,\u00a0management,\u00a0policy\u00a0and workload\u00a0execution\u00a0stay\u00a0within the customer-operated environments,\u00a0so\u00a0services\u00a0continue\u00a0running securely even when environments must be isolated or connectivity is not available.\u00a0Using\u00a0familiar Azure experiences and consistent policies,\u00a0organizations\u00a0can deploy and govern workloads locally\u00a0without depending on continuous connection to public cloud services.\u00a0Azure Local is designed to scale with mission-critical needs from smaller deployments to larger footprints that support data-intensive and AI-driven workloads. Customers can start fast, expand over\u00a0time\u00a0and\u00a0maintain\u00a0a unified operational model, all within their sovereign boundary.<\/p>\n
Operating\u00a0in disconnected environments\u00a0surfaces\u00a0constraints that go beyond traditional cloud assumptions:\u00a0External dependencies may be unacceptable, connectivity may be intentionally\u00a0restricted\u00a0and operational continuity\u00a0is a business imperative.\u00a0<\/p>\n
\u201cThe availability of Azure Local disconnected operations\u00a0represents\u00a0a breakthrough for organizations that need control over their data without sacrificing the power of the Microsoft\u00a0Cloud. For Luxembourg, where digital sovereignty is not just a principle but a strategic necessity, this model offers the resilience, autonomy and trust our market expects. By combining Microsoft\u2019s technological leadership with Proximus NXT\u2019s sovereign cloud\u00a0expertise, we are enabling our customers to innovate confidently\u00a0\u2014\u00a0even in fully disconnected mode,\u201d\u00a0said Gerard Hoffmann, CEO Proximus Luxembourg.\u00a0<\/p>\n
Microsoft 365 Local keeps\u00a0productivity and collaboration available in\u00a0fully\u00a0disconnected environments\u00a0<\/p>\n
As sovereign environments move into\u00a0disconnected environments,\u00a0keeping\u00a0people\u00a0productive becomes just as critical as keeping infrastructure online.\u00a0Building\u00a0on more than a decade of\u00a0delivering and supporting\u00a0these services,\u00a0Microsoft 365 Local\u00a0disconnected\u00a0brings that continuity to the productivity layer, delivering\u00a0Microsoft\u2019s core server workloads\u00a0\u2014\u00a0Exchange Server,\u00a0SharePoint Server\u00a0and\u00a0Skype for Business Server\u00a0supported through\u00a0at least\u00a02035\u00a0\u2014\u00a0directly into the customer\u2019s\u00a0sovereign private cloud.\u00a0\u00a0<\/p>\n
With Microsoft 365 Local,\u00a0teams can\u00a0communicate, share\u00a0information\u00a0and\u00a0collaborate securely within the same controlled boundary as their infrastructure and AI workloads. Everything runs\u00a0locally, under\u00a0customer-owned policies, with full control of data resiliency,\u00a0access\u00a0and compliance.\u00a0By\u00a0operating\u00a0with\u00a0Azure-consistent\u00a0management\u00a0and governance, customers get the productivity experience they rely on, designed to stay resilient and secure even when offline.\u00a0<\/p>\n
Bringing\u00a0large\u00a0models and\u00a0modern\u00a0infrastructure\u00a0to\u00a0Foundry Local\u00a0<\/p>\n
With the availability of larger models and modern infrastructure as part of the Foundry Local portfolio, Microsoft is enabling customers with highly secure environments the\u00a0ability\u00a0to run\u00a0multimodal, large\u00a0models\u00a0directly inside\u00a0their sovereign private cloud\u00a0environments. This\u00a0brings the richness of\u00a0Microsoft\u2019s\u00a0enterprise\u00a0AI capabilities\u00a0to\u00a0on-premises systems, complete with\u00a0local inferencing\u00a0and\u00a0APIs\u00a0that\u00a0operate\u00a0completely within\u00a0customer-controlled data boundaries.\u00a0\u00a0<\/p>\n
Expanding beyond small models, the integration of Foundry Local with Azure Local is specifically designed to support large-scale models\u00a0utilizing\u00a0the latest GPUs from partners such as NVIDIA. Microsoft will provide comprehensive support for deployments,\u00a0updates\u00a0and operational health. Even as inferencing demands increase over\u00a0time, customers\u00a0retain\u00a0complete control over their data and hardware.\u00a0\u00a0<\/p>\n
Choice and control without\u00a0added\u00a0complexity\u00a0<\/p>\n
Customers\u00a0facing strict sovereignty and\u00a0regulatory\u00a0requirements\u00a0are clear that\u00a0a\u00a0fully disconnected sovereign private cloud is a key business\u00a0need. Microsoft Sovereign Private Cloud is designed to meet these needs head-on, enabling secure, compliant operations even in environments with no external connectivity. At the same time, we recognize that disconnected\u00a0environments are not one-size-fits-all; some\u00a0customers\u00a0operate\u00a0across connected, hybrid and disconnected\u00a0modes\u00a0based on\u00a0mission,\u00a0risk\u00a0and\u00a0regulation. Our approach\u00a0helps\u00a0customers\u00a0to\u00a0meet\u00a0strict sovereign requirements in fully disconnected scenarios\u00a0without\u00a0compromising simplicity, while\u00a0retaining\u00a0flexibility where connectivity is possible.\u00a0Together, Azure Local\u00a0disconnected operations,\u00a0Microsoft 365 Local\u00a0and Foundry Local\u00a0help organizations choose where workloads run and how environments are managed, while standardizing governance and operational practices across connected and disconnected deployments.\u00a0<\/p>\n
