ECas_cc_v5 and ECads_cc_v5-series (Preview)

Applies to: ✔️ Linux VMs in Azure Kubernetes Service

Note

Preview Terms - These VM sizes are subject to the Supplemental Terms of Use for Microsoft Azure Previews.

Note

Confidential child capable VMs are currently enabled only through Azure Kubernetes Service (AKS) when you choose these VMs as your agent node sizes. If you wish to enable it outside AKS, please contact azconfidentialpm@microsoft.com.

Confidential child capable VMs allow you to borrow resources from the parent VM you deploy, to create AMD SEV-SNP protected child VMs. The parent VM has almost complete feature parity with any other general purpose Azure VM (for example, E-series VMs). This parent-child deployment model can help you achieve higher levels of isolation from the Azure host and parent VM. These confidential child capable VMs are built on the same hardware that powers our Azure confidential VMs. Azure confidential VMs are now generally available.  

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. For more information on disk types, see What disk types are available in Azure?

Note

There are some pricing differences based on your encryption settings for nested confidential VMs.

ECas_cc_v5-series products

The ECas_cc_v5-series sizes offer a combination of vCPU and memory for most production workloads. The ECas_cc_v5-series sizes offer a combination of vCPU and memory that is ideal for memory-intensive enterprise applications. These new VMs with no local disk provide a better value proposition for workloads that do not require local temp disk.

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).
