These virtual machines are in public preview and not recommended for production usage. Please sign up at aka.ms/acc/v6preview for access. These VMs are available in West Europe, East US, West US and West US 3.
The ECesv6-series are Azure confidential VMs that can be used to protect the confidentiality and integrity of your code and data while it's being processed in the public cloud. Organizations can use these VMs to seamlessly bring confidential workloads to the cloud without any code changes to the application.
These machines are powered by Intel® 5th Generation Xeon® Scalable processors reaching an all-core turbo clock speed of 3.0 GHz and Intel® Advanced Matrix Extensions (AMX) for AI acceleration.
Featuring Intel® Trust Domain Extensions (TDX), these VMs are hardened from the cloud virtualized environment by denying the hypervisor, other host management code and administrators access to the VM memory and state. It helps to protect VMs against a broad range of sophisticated hardware and software attacks.
These VMs have native support for confidential disk encryption meaning organizations can encrypt their VM disks at boot with either a customer-managed key (CMK), or platform-managed key (PMK). This feature is fully integrated with Azure KeyVault or Azure Managed HSM with validation for FIPS 140-2 Level 3.
Note
There are some pricing differences based on your encryption settings for confidential VMs.
Note
Certain applications which are time sensitive may experience asynchronous time at VM boot. Whilst a long-term fix is in development, a workaround is available for Linux customers today. If you need additional support, please create a support request.

ECesv6-series
The ECesv6 VMs offer even higher memory to vCPU ratio and an all new VM size with up to 64 vCPUs and 512 GiB of RAM. These VMs are ideal for memory intensive applications, large relational database servers, business intelligence applications, and critical applications that process sensitive and regulated data.
This series supports Standard SSD, Standard HDD, and Premium SSD disk types. Billing for disk storage and VMs is separate. To estimate your costs, use the Pricing Calculator.

Size table definitions
Storage capacity is shown in units of GiB or 1024^3 bytes. When you compare disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1023 GiB = 1098.4 GB.
Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.
Data disks can operate in cached or uncached modes. For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. For uncached data disk operation, the host cache mode is set to None.
To learn how to get the best storage performance for your VMs, see Virtual machine and disk performance.
Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. For more information, see Virtual machine network bandwidth.
Upper limits aren't guaranteed. Limits offer guidance for selecting the right VM type for the intended application. Actual network performance will depend on several factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimize network throughput for Azure virtual machines. To achieve the expected network performance on Linux or Windows, you may need to select a specific version or optimize your VM. For more information, see Bandwidth/Throughput testing (NTTTCP).
