Read on to uncover how the team enabled the largest cryptographic workload ever run in Azure—built on high-assurance infrastructure designed for secure, high-throughput operations. Migrating highly secure workloads is made possible with the help of Confidential computing and Managed HSM empowering organizations handling highly secure, high-throughput, and confidential workloads to operate with greater confidence, flexibility, and value. Advancing Security and Throughput The Microsoft Windows Key Management Licensing Service (MKMS) is built around the protection and management of high-value cryptographic keys, which are central to its security model. This service processes billions of licensing requests and related cryptographic operations each day, using these keys to ensure that only authorized individuals have access to their Windows operating systems, desktop applications, and games. Through its focus on secure key management, MKMS supports the authenticity of software licenses and the protection of sensitive data, making secure Windows licensing possible on a global scale. With the integration of Confidential Virtual Machines (CVM) and Managed Hardware Security Modules, the service now meets modern high-security requirements by extending this rigorous protection into the cloud environment. This evolution not only reinforces Microsoft's dedication to safeguarding sensitive cryptographic operations but also ensures that customers can trust the reliability and security of their licensing experience. Building Trust by Moving to Azure Transitioning from multiple highly secure on-prem datacenters to strategically selected Azure regions has enabled greater reliability, stronger security, and a seamless customer experience for the service. This migration not only aligns with Microsoft’s Secure Future Initiative and delivers CAPEX savings by eliminating the need for hardware refreshes but also unlocks the benefits of cloud-native solutions powered by Confidential Computing and Azure Key Vault Managed HSM. Migrating MKMS licensing service from on-premises infrastructure to Azure has delivered significant operational benefits. Azure’s elastic cloud resources allow us to scale efficiently, adapting to changing workload demands and supporting future growth while optimizing costs by paying only for the resources we use. Distributing services across multiple geographic regions in Azure has substantially improved our service availability, minimizing downtime and maintaining consistent delivery even during unexpected events. This geographic redundancy ensures our customers experience fewer disruptions. By utilizing Azure’s performance-driven infrastructure, we have reduced upfront hardware investments and ongoing maintenance costs, while still meeting the high throughput, speed, and reliability necessary for large-scale cryptographic operations—achieving results on par with or better than our previous on-premises environment. Enabling Security with Azure Confidential Computing At the heart of this transformation lies Azure Confidential Computing based on 4th generation AMD EPYC™ CPUs with SEV-SNP, which safeguards sensitive data during processing through hardware-based Trusted Execution Environments (TEEs). This technology prevents unauthorized access, including by cloud administrators and datacenter operators, ensuring robust confidentiality for cryptographic operations that are central to the authenticity of software licenses. Azure encrypts data at rest and in transit, while confidential computing further secures data in use. This added layer of protection addressed essential security requirements for migrating secure workloads to Azure, supporting the safety and integrity of customer data. The migration also incorporated Azure Managed HSM to provide enhanced security and tighter control over cryptographic keys. Complemented by Confidential Virtual Machines and securely attested OS images, the service now operates in a trusted and isolated environment, delivering a resilient and scalable cryptographic foundation —crucial for managing high value cryptographic keys required for Windows licensing. Setting a Benchmark for High-Scale Cryptographic Services Microsoft’s Key Management Licensing Service, leveraging Azure Confidential Computing and the specially engineered high-throughput Managed HSM capabilities, delivers advanced performance for securely hosting confidential, high-scale workloads in the cloud. These enhanced MHSM features were designed and built to meet the immense demand of this service, enabling it to support the highest throughput cryptographic workload ever run on Azure to date. MKMS is deployed on Azure using a purpose-built, internally attested secure image to ensure a trusted baseline. The deployment leverages Azure confidential VMs, and managed hardware security modules to protect data: all data at rest and in transit is encrypted, with encryption keys secured by FIPS-validated HSMs. In addition, CVM guarantees our service that all data in-use is encrypted and secure as an additional layer of security. Comprehensive logging and monitoring are enabled across the stack: control-plane operations, host OS events, and network traffic are all recorded and analyzed for auditing and threat detection. This defense-in-depth design layers protection from the hardware and hypervisor up through network firewalls and application-level safeguards, ensuring comprehensive resilience against both volumetric and application-targeted attacks. Summary In summary, migration of Windows Licensing to Azure signifies Microsoft’s commitment to driving innovation and security in the cloud. By leveraging Confidential Computing and Managed HSMs, Microsoft is delivering value to billions of users worldwide while reinforcing the trust placed in its services. This achievement highlights the potential of cloud-native technologies to transform traditional mission-critical systems, offering a glimpse into the future of secure and scalable computing.Preview of Azure Confidential Clean Rooms for secure multiparty data collaboration
