Cloud server configurations
When creating a cloud server you can choose the number of vCPUs, RAM, the size of the local disk (optional), and add GPUs. Depending on the tasks for which you need a cloud server, you can choose a configuration from a specific line that fits these tasks.
Two types of server configurations are available for all lines, except Shared and Dedicated:
- prebuilt configurations — configurations of lines with different specifications, in which the resource ratio is fixed;
- custom configurations — configurations in which any resource ratio can be specified.
The configurations use different processors depending on the line and pool segment. You can customize the selected configuration. After creating a cloud server, you can change the configuration.
Processors
Available processors vary by line.
Standard
GPU
Shared
HighFreq
10G Net
Dedicated
Processor with DDR4 REG 2450 MHz and processor with DDR5 REG 2250–2450 MHz for cloud servers with allocated cores.
Processors with DDR4 REG 2133–2633 MHz for configurations without allocated cores.
Lines
To see the availability of configurations in the regions, see the Cloud servers availability matrix.
You can choose the configuration when creating a cloud server in the control panel. If you want to create a cloud server with a fixed configuration via the OpenStack CLI and Terraform, use the List of fixed configuration flavors in all pools table. If fixed configurations do not work for you, create a flavor. You can create a flavor with a GPU via the OpenStack API.
Depending on the line, fixed configurations offer up to 240 vCPUs, 1000 GB of RAM, and 3.2 TB of local disk space, while custom configurations offer up to 232 vCPUs, 900 GB of RAM, and 3.2 TB of local disk space.
Standard
Prebuilt configuration
Custom configuration
Fixed configurations of a cloud server line with a balanced vCPU:RAM resource distribution. Suitable for most tasks, such as running code for web services and applications, hosting online stores, or creating test environments.
In the Standard line, a local or network boot disk is available.
In this line, cloud server configurations with allocated cores are available in the multi-zone pool ru-6 and in pool segments ru-3b, ru-7a, and ru-7b. For cloud servers with allocated cores, from 2 to 32 vCPUs, from 4 GB to 256 GB of RAM, and from 32 GB to 1 TB of local disk are available.
For basic cloud servers, from 1 to 32 vCPUs, from 1 GB to 128 GB of RAM, and from 16 GB to 1 TB of local disk space are available.
GPU
Prebuilt configuration
Custom configuration
Fixed cloud server configurations with dedicated GPUs.
Optimized for GPU computing, such as video transcoding, neural network training, or creating remote workstations.
Available from 4 to 48 vCPUs, from 1 to 8 GPUs, and from 16 GB to 450 GB of RAM.
In the GPU line, local or network boot disks are available. For cloud servers with a local disk, you can only use GPUs that support local disks.
Read more about dedicated GPUs in the Graphics Processing Units (GPU) instruction.
Shared
Fixed cloud server configurations with the ability to use and pay for only a portion of a vCPU.
Shared line configurations are less expensive than other lines and are suitable for tasks that do not require constant and full utilization of a virtual core, such as launching staging, a website, setting up a network, or training.
In the Shared line, one virtual core can be used by multiple clients simultaneously. When creating such a configuration, you must specify the share of vCPU to be reserved for your server: 10%, 20%, or 50%. The performance of the cloud server will never fall below the specified share and may temporarily reach 100% if other clients are not using resources at maximum capacity or if part of the virtual core is not leased.
Only network boot disks are available in the Shared line.
Available from 1 to 4 vCPUs and from 512 MB to 8 GB of RAM.
Custom configurations are not available.
HighFreq
Prebuilt configuration
Custom configuration
Fixed configurations of high-performance cloud servers with processor frequencies up to 3.6 GHz, and memory — 3,200 MHz. Suitable for databases, for example, 1C Bitrix, game servers, and other tasks requiring high processing and response speeds.
Local boot disks are available in the HighFreq line.
In this line, fixed configurations are available to support cloud servers with allocated cores in the multi-zone pool ru-6 and in pool segments ru-3b, ru-7a, and ru-7b. For cloud servers with allocated cores, from 2 to 64 vCPUs, from 4 GB to 256 GB of RAM, and from 30 GB to 1 TB of local disk are available.
For basic cloud servers, from 1 to 64 vCPUs, from 2 GB to 256 GB of RAM, and from 30 GB to 1.5 TB of local disk space are available.
10G Net
Prebuilt configuration
Custom configuration
Fixed configurations of a line with support for high-speed 10 Gbps networks in pool segments ru-3b, ru-7a, and ru-7b. Configurations in this line are only available with support for cloud servers with allocated cores.
Suitable for high-load web applications, network services, game servers, and other tasks that require high network throughput for transferring large amounts of data.
Available 16 vCPUs, from 32 GB to 128 GB of RAM, and from 256 GB to 2 TB of local disk space.
Dedicated
Fixed configurations of a line with support for a cloud server on a dedicated host in pool segment ru-3b. Configurations in this line are only available with support for cloud servers with allocated cores.
Suitable for software with physical hardware ties, applications and services with isolation requirements for computing loads, and high-load services.
Available 14 vCPUs, 64 GB or 86 GB of RAM.
Custom configurations are not available.
List of cloud server line flavors
Flavors correspond to cloud server configurations and define the number of vCPUs, RAM, and local disk size (optional) of the server.
Flavor IDs or names are used to create cloud servers through the OpenStack CLI and Terraform. IDs differ across pools.
For example, 1015 is the ID, and SL1.4-16384 is the flavor name that corresponds to a fixed configuration of the Standard line with 4 vCPUs and 16 GB of RAM in pool ru-9.
If there is no fixed-configuration flavor for the line with the required number of vCPUs, RAM, and local disk size, you can create a flavor.
You can view the list of fixed-configuration flavors in all pools in a table or view a list of flavors for all configurations in a specific pool through the OpenStack CLI.
