Product Description Cloud Servers

A cloud server is a virtual server of a fixed or arbitrary configuration that runs on Selectel physical resources. Selectel uses the KVM hypervisor as the virtualization system for its physical resources.

Terms of use for the Cloud Servers product are defined by the document Terms of Use for Individual Services: Cloud Platform Service Group and SLA . All cloud servers by default comply with 152-FZ.

If mandatory certification of an information system, use of certified security tools only, or processing of security levels 1 and 2 personal data is required, deploy the server in the certified cloud.

In addition to a standard cloud server, you can create a preemptible server in Selectel at a discount of up to 75%. A preemptible cloud server runs continuously for no more than 24 hours and can be stopped by Selectel at any time. Terms of use do not apply to preemptible servers.

Cloud servers can be created in different locations. For details, see the Cloud Server Availability by Location guide.

To work with cloud servers, user types and roles, projects, and project limits and quotas are supported.

Use cases

  • hosting web projects: web applications, online stores, corporate websites, portals, and other internet resources;
  • hosting software and corporate infrastructure services (CRM, ERP, databases, mail servers, and others);
  • creation, development, and testing of applications;
  • running containerized applications and microservice architectures;
  • performing load testing and organizing CI/CD processes;
  • scaling fault-tolerant web services during peak loads;
  • rendering graphics, animations, and visual effects;
  • performing GPU-accelerated computing for scientific and engineering tasks;
  • inference of machine learning and artificial intelligence models;
  • running and maintaining large language models (LLMs), chatbots, RAG systems, and AI agents;
  • organizing remote workplaces and virtual desktops.

How it works

To get started, create a cloud server. You can create a server:

When creating a server, you select a product line and a specific configuration suitable for your tasks. For most product lines, two types of configurations are available:

  • fixed configuration — a configuration with a fixed ratio of CPU cores, memory, and disks;
  • custom configuration — a ratio of CPU cores, memory, and disks adjustable to your needs.

Depending on the tasks your cloud server will handle, you can:

How to work with cloud servers

Once you have created a server, you can manage it:

For remote access to the cloud server, you can connect in several ways.

You can track cloud server metrics using the Metrics service.

Records of operations on cloud servers are saved in audit logs.

Areas of responsibility

Areas of responsibility at Selectel correspond to the division of responsibilities in the IaaS cloud service delivery model.

Selectel provides

  • a virtualization environment and computing systems;
  • physical security and fault tolerance of servers, and power supply;
  • collection and analysis of hypervisor and infrastructure component events;
  • protection against DDoS and network attacks;
  • traffic encryption and filtering.

Selectel is not responsible for

  • configuration of cloud servers: the operating system, network, and firewall;
  • security of the virtual network and user accounts;
  • resource access control;
  • cloud server backup;
  • encryption and data integrity verification.

You manage the cloud server yourself: you install and configure the necessary software.

If you need help administering cloud servers, order the Managed Services service.

Pricing

Cloud servers are billed according to the pay-as-you-go payment model. Funds are deducted from the balance every hour for the previous hour of using cloud server resources. Outbound traffic exceeding 3 TB across all Cloud Platform projects is also billed. For details, see the Payment Models and Prices guide.

What is included in the price

The price of a cloud server includes:

Limits and restrictions

Total bandwidth for UDP traffic to ports 0, 16, 19, 53, 123, and 1900 is limited to 500 Mbps.

If the threshold of 150 000 packets per second is exceeded, Selectel limits the bandwidth to 100 Mbit/s.

Selectel sets account and project limits, as well as resource quotas. For details, see the Quotas and limits guide

In Selectel, some TCP/UDP ports are blocked by default, including ports 25, 465, and 587. You can submit a request to unblock ports. To send emails, you can use the Selectel email service.

Access from Selectel infrastructure to public subnets of the e-government (Gosuslugi portal and related services) is also blocked. To unblock it, request access to e-government subnets.

Cloud servers do not support nested virtualization. If nested virtualization is required for your tasks, consider dedicated servers or Managed Kubernetes clusters on dedicated servers.
