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
You can check the availability of configurations in the regions in the Cloud Servers availability matrix.
The configuration can be selected when creating a cloud server in the control panel. If you want to create a cloud server with a fixed configuration via OpenStack CLI and Terraform, use the list of fixed-configuration flavors in all pools. If fixed configurations do not suit your needs, create a flavor. You can create a flavor with a GPU via OpenStack API.
Depending on the line, up to 240 vCPU, 1000 GB of RAM, and 3.2 TB of local disk are available in fixed configurations, and up to 232 vCPU, 900 GB of RAM, and 3.2 TB of local disk in custom ones.
Standard
Fixed configuration
Custom configuration
Fixed configurations of a line of cloud servers with a balanced vCPU:RAM resource distribution. Suitable for most tasks, such as executing code for web services and applications, hosting online stores, and creating test environments.
A local or network boot disk is available in the Standard line.
The line offers cloud servers with dedicated cores in the multi-zone pool ru-6 and pool segments ru-3b, ru-7a, and ru-7b. For cloud servers with dedicated cores, 2 to 32 vCPU, 4 GB to 256 GB of RAM, and 32 GB to 1 TB of local disk are available.
For basic cloud servers, 1 to 32 vCPU, 1 GB to 128 GB of RAM, and 16 GB to 1 TB of local disk are available.
GPU
Fixed configuration
Custom configuration
Fixed configurations of cloud servers with dedicated GPUs.
Optimized for GPU-based computing, such as video transcoding, neural network training, or creating remote workstations.
1 to 8 GPU, 4 to 240 vCPU, 16 GB to 450 GB of RAM, and 64 GB to 6.8 TB of local disk are available.
Local or network boot disks are available in the GPU line. For cloud servers with a local disk, you can only use GPUs with local disk support.
Read more about dedicated GPUs in the Graphics Processors (GPU) guide.
Shared
Fixed configurations of cloud servers with the ability to use and pay for only a portion of a vCPU.
Shared line configurations are cheaper than other lines and are suitable for tasks that do not require constant and full utilization of a virtual core, such as running a staging environment, a website, bringing up a network, or training.
In the Shared line, one virtual core can be used by several clients simultaneously. When creating such a configuration, you need to specify the portion of the vCPU that will be reserved for your server: 10%, 20%, or 50%. The performance of the cloud server will never drop below the specified portion and may temporarily reach up to 100% if other clients are not using their resources to the maximum or if a part of the virtual core is not leased.
Only network boot disks are available in the Shared line.
In fixed configurations, 1 to 4 vCPU and 512 MB to 8 GB of RAM are available.
Custom configurations are not available.
HighFreq
Fixed configuration
Custom configuration
Fixed configurations of high-performance cloud servers with processor frequencies up to 3.6 GHz and memory frequencies up to 3,200 MHz. Suitable for databases (e.g., 1C Bitrix), game servers, and other tasks requiring high processing and response speeds.
Local boot disks are available in the HighFreq line.
The line offers fixed configurations to support cloud servers with dedicated cores in the multi-zone pool ru-6 and pool segments ru-3b, ru-7a, and ru-7b. For cloud servers with dedicated cores, 2 to 64 vCPU, 4 GB to 256 GB of RAM, and 30 GB to 1 TB of local disk are available.
For basic cloud servers, 1 to 64 vCPU, 2 GB to 256 GB of RAM, and 30 GB to 1.5 TB of local disk are available.
10G Net
Fixed configuration
Custom configuration
Fixed configurations of a line with support for fast 10 Gbit/s networks in pool segments ru-3b, ru-7a, and ru-7b. Line configurations are only available with support for cloud servers with dedicated cores.
Suitable for high-load web applications, network services, game servers, and other tasks that require high network bandwidth when transferring large volumes of data.
16 vCPU, 32 GB to 128 GB of RAM, and 256 GB to 2 TB of local disk are available.
Dedicated
Fixed configurations of a line with support for running a cloud server on a dedicated host in pool segments ru-3b and ru-6a. Line configurations are only available with support for cloud servers with dedicated cores. There are also configurations with GPUs.
Suitable for software with hardware binding, applications and services with isolation requirements for computational workloads, and high-load services.
In fixed configurations with CPU, 18 or 34 vCPU and 64 GB or 86 GB of RAM are available. In configurations with GPU, 48 or 96 vCPU, 48 GB or 72 GB of RAM, and 512 GB or 1 TB of local disk are available.
Custom configurations are not available.
List of cloud server line flavors
Flavors correspond to cloud server configurations and determine the number of vCPU, RAM, and size of the local disk (optional) of the server.
To create cloud servers through OpenStack CLI and Terraform, flavor IDs or names are used. IDs differ in pools.
For example, 1015 is the ID, and SL1.4-16384 is the name of a flavor that corresponds to a fixed configuration of the Standard line with 4 vCPU and 16 GB of RAM in the ru-9 pool.
If there is no fixed-configuration flavor for a line with the required amount of vCPU, 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 via OpenStack CLI.
