Additional security enhancements

With the launch of the DCasv6 and ECasv6 confidential VM family – we support AES-256 memory encryption enabled by default. Additionally, we now offer our customers the capability to leverage key protection with Virtualization-based Security (VBS) in Windows. By enabling key protection in Windows CVMs, customers can protect keys in-use from Guest OS and applications. This key protection is enforced by CPU hardware.

Faster performance for confidential workloads

These new CVMs have demonstrated up to 25% improvement in various benchmarks compared to our previous generation of AMD-based confidential VMs.

KT is leveraging Azure confidential computing to secure sensitive and regulated data from its telco business in the cloud. With new V6 CVM offerings in Korea Central Region, KT extends its use to help Korean customers with enhanced security requirements, including regulated industries, benefit from the highest data protection as well as the fastest performance by the latest AMD SEV-SNP technology through its Secure Public Cloud built with Azure confidential computing. - Woojin Jung, EVP, KT Corporation

Worldwide Region Availability

These CVMs will be gradually made available across all supported Azure regions and availability zones. Please use the sign-up form to indicate interest in participating in the gated preview and regional requirements.

General purpose & Memory-intensive workloads

Featuring general purpose optimized memory-to-vCPU ratios and support up to 96 vCPUs and 384 GiB RAM, the DCasv6-series delivers enterprise-grade performance. The DCasv6-series enables organizations to run sensitive workloads with hardware-based security guarantees, making them ideal for applications processing regulated or confidential data.

For more memory demanding workloads, the new ECasv6-series offer high memory-to-vCPU ratios with increased scalability up to 96 vCPUs and 672 GiB of RAM. The ECasv6-series is ideal for memory-intensive enterprise applications offering nearly double the memory capacity of DCasv6. The ECasv6-series scales 672 GiB RAM with up to 96 vCPUs, making them ideal for memory intensive applications that exceed even the capabilities of the DCasv6 series.

OS Support

These CVMs support the following guest operating systems: Windows Server 2019, 2022, 2025, Windows 11, Ubuntu 22.04, Ubuntu 24.04, and RHEL 9.4.

Endorsements from our customers

The BMW Group relies on Azure confidential VMs powered by AMD EPYC processors to enable a Zero Trust environment with end-to-end encryption for our identity authentication system, allowing over 200,000 associates to collaborate on building the future of individual mobility. The solution was made possible in part due to the fact that AMD EPYC processor based confidential VMs do not require code changes to protect data in memory. Further, our testing of the newest generation of DCasv6 VMs has shown significant improvements in performance, and we look forward to seeing them go live on Azure. - BMW Group
