Shared-core VMs

The E2 machine series also contains shared-core machine types that use context- switching to time-share a physical core between vCPUs for multitasking. Different shared-core machine types sustain different amounts of time on a physical core.

Unlike predefined machine types and custom machine types, shared-core machine types have a predefined price that includes both vCPUs and memory. For more information, see VM instance pricing .

CPU bursting

Shared-core machine types offer bursting capabilities that allow instances to use additional physical CPU for short periods of time. Bursting happens automatically when your VM requires more physical CPU than originally allocated. During these spikes, your VM will opportunistically take advantage of available physical CPU in bursts. Note that bursts are not permanent and are only possible periodically.

• e2-micro , e2-small , and e2-medium shared-core VMs can burst for dozens of seconds.
• If the CPU is utilized at 100%, then the burst lasts as follows:
• e2-micro : 30 seconds
• e2-small : 60 seconds
• e2-medium 120 seconds

The exact burst time is determined by a Token bucket meaning utilizing the CPU less than 100% will result in longer bursts. Bursting doesn't incur any additional charges. You are charged the listed on-demand price for e2 shared-core , f1-micro , and g1-small VMs.

This series is available only in select regions and zones .

The Tau T2A machine series doesn't support simultaneous multithreading (SMT); each vCPU is equivalent to an entire core.

Tau T2A Limitations

The Tau T2A machine series does not support:

• Custom machine types
• Sole tenant nodes
• Nested virtualization
• Extreme Persistent Disk
• Local SSD
• Regional Persistent Disk
• Virtio-SCSI Storage Controller and Virtio-Net Ethernet Adapter
• Windows Server or Windows Client OS
• 32-bit mode ELO (guest userspace support)
• Committed use discounts (CUDs) or Sustained use discounts (SUDs) ; however, it offers Spot VM discounts .
• Virtual display devices

T2A supports the Secure boot feature, but not all public OS images for T2A support secure boot.

Supported disk types for T2A

T2A VMs support only the NVMe disk interface and can use the following block storage types:

• Zonal standard Persistent Disk ( pd-standard )
• Zonal balanced Persistent Disk ( pd-balanced )
• Zonal SSD (performance) Persistent Disk ( pd-ssd )

For VMs running Microsoft Windows and using the NVMe disk interface, the combined number of both Hyperdisk and Persistent Disk attached volumes can't exceed a total of 16 disks. See Known issues . Local SSD volumes are excluded from this issue.

Tau T2D machine series

The Tau T2D machine series run on the third generation AMD EPYC Milan processor with a base frequency of 2.45 GHz, an effective frequency of 2.8 GHz, and a max boost frequency of 3.5 GHz. This series has predefined machine types of up to 60 vCPUs, support 4 GB of memory per vCPU, and a maximum of 32 Gbps outbound data transfer. It also supports the following discount and consumption options:

• Resource-based committed use discounts (CUDs)
• Spot VMs
• Reservations

This series is available only in select regions and zones .

Machine types in the Tau T2D machine series have simultaneous multithreading (SMT) disabled; therefore a vCPU is equivalent to an entire core.

Tau T2D Limitations

Tau T2D VMs do not support:

• Local SSD
• Regional Persistent Disk
• Custom VMs
• Sole-tenant nodes
• Extreme Persistent Disk
• GPUs
• Nested virtualization
• Flexible CUDs
• Sustained use discounts (SUDs)
• Confidential VMs

Supported disk types for T2D

T2D VMs support both the SCSI and the NVMe disk interface and can use the following block storage types:

• Zonal standard Persistent Disk ( pd-standard )
• Zonal balanced Persistent Disk ( pd-balanced )
• Zonal SSD (performance) Persistent Disk ( pd-ssd )
• Hyperdisk Throughput ( hyperdisk-throughput )

Custom machine types

If none of the predefined machine types in the general-purpose machine family match your workload needs, you can create a VM with a custom machine type.

Creating a VM with a custom machine type is ideal for workloads that require more processing power or more memory, but don't need all of the upgrades that are provided by the next larger predefined machine type.

It costs slightly more to use a custom machine type than an equivalent predefined machine type, and there are limitations in the amount of memory and vCPUs that you can select. The on-demand prices for custom machine types include a 5% premium over the on-demand and commitment prices for predefined machine types.

You can create a VM with a custom machine type for only the N and E machine series in the general-purpose machine family. Custom machine types are not available for the C and Tau machine series. Custom machine types are subject to the same Persistent Disk limits as E2, N2, and N1 predefined machine types. The maximum total Persistent Disk size for each VM is 257 TiB and the max number of Persistent Disk is 128. N4 custom machines types are subject to the limitations of Hyperdisk capacity storage.

If a custom machine type doesn't meet your requirements, it's possible to customize the number of visible CPU cores on many machine types. It's also possible to set the number of threads per core for certain machine types. You can make these changes during VM instance creation, or by editing an existing VM instance. Reducing the number of visible cores might impact the cost of your VMs. Be sure to review pricing prior to making any changes.
