Azure’s next generation of Confidential Computing Virtual Machines, powered by advanced 5th Gen Intel® Xeon® processors featuring Intel® Trust Domain Extensions (Intel® TDX), empower organizations to transition their confidential workloads to the cloud seamlessly, without requiring code modifications to existing applications. The supported Virtual Machines (VMs) include the general-purpose DCesv6-series and the memory optimized ECesv6-series families.
Azure Confidential Computing VMs are meticulously designed for tenants with stringent security and confidentiality needs, offering a robust, attestable, hardware-enforced boundary. They ensure that data and applications remain private and encrypted during use, maintaining encryption of sensitive code and other data in memory throughout processing.
This next generation of Confidential Computing VMs introduces a plethora of improvements and new features. Notably, these VMs utilize our innovative open-source paravisor, OpenHCL. This breakthrough technology increases transparency for customers, affirming our dedication to the "trust but verify" principle.
In addition, the new VMs support Azure Boost, delivering up to 205k IOPS and 4 GB/s throughput for remote storage, along with 54 GBps VM network bandwidth. Intel TDX's capabilities within the Confidential Computing VMs have been enhanced by integrating features from general-purpose and other confidential VM offerings. These improvements include Guest Attestation support and the incorporation of Intel® Tiber™ Trust Authority, providing enterprises with operator-independent attestation.
The DCesv6-series VMs are designed to offer a balanced memory-to-vCPU ratio, featuring up to 128 vCPUs and 512 GiB of memory. Meanwhile, the ECesv6-series VMs are optimized for higher memory-to-vCPU ratios, providing up to 64 vCPUs and 512 GiB of memory.
Get started today with DCesv6-series or ECesv6-series, which are available now in preview in the East US, West US, West US 3 and West Europe regions. Supported OS images include Windows Server 2025, Windows Server 2022, Ubuntu 22.04, and Ubuntu 24.04. Please sign up at aka.ms/acc/v6preview and we will reach out to you.
