Yandex Cloud · Network and Server Infrastructure

Location: ru-central1-b Resource type: Virtual Machines (Yandex Cloud)

RFC NOTE: This document describes the current state of the DSP infrastructure deployed in Yandex Cloud. It is intended for operational overview, capacity planning, and architectural reviews.

1. Assumptions

RFC NOTE: At the VM abstraction level, physical CPU topology is not exposed. For consistency across all environments, the following assumption is used throughout this document.

  • 1 vCPU is treated as 1 CPU core

This assumption is standard for cloud-based infrastructure documentation and sufficient for capacity and scaling discussions.

RFC NOTE: Kafka brokers do not have public IP addresses by design. All inter-broker and client communication is performed over the internal VPC network.

3. Aggregate Resources

  • Total servers: 13

  • Total CPU cores: 42

  • Total RAM: 132 GB

  • Availability zone: ru-central1-b

RFC NOTE: Aggregate values are provided for high-level capacity estimation. They must not be interpreted as a single failure domain or a shared resource pool.

4. Infrastructure Diagram

The diagram below illustrates the Yandex DSP infrastructure, including managed services.

RFC NOTE: This AsciiDoc document is located under /architecture. The Mermaid diagram is stored under /architecture/diagrams/mermaid/ and serves as a visual complement to the tabular data above.

5. Managed Data Services

RFC NOTE: The following components are provided as managed services by Yandex Cloud. They are not represented as virtual machines and therefore are excluded from the server inventory table.
