Cloud Interconnect terminologyCloud Interconnect terminology

• CIC: Abbreviated name for Yandex Cloud Interconnect.
• PoPs: Points of presence, i.e., commercial communication hubs hosting third-party network equipment, including the Yandex Cloud equipment.
• Cross-connect (XC): Two optical fibers at the point of presence connecting the physical port of the customer or telecom provider equipment to the physical port of the Yandex Cloud equipment.
• Transceiver: Optical module installed on the customer and Yandex Cloud equipment ports. It provides termination for the optical fibers of the cross-connect.
• Telecom provider: Telecommunication service provider that has its own equipment at a point of presence. Typically, you need a cross-connect to connect to the Yandex Cloud equipment via a telecom provider.
• Trunk: Physical connection at a point of presence between the Yandex Cloud equipment and the customer or telecom provider equipment.
• Private connection (PRC): Connection between the customer site (on-prem) and a routing instance.
• Public connection: Logical connection between the customer site (on-prem) and Yandex Cloud services without using VPC.
• Support: Yandex Cloud technical support team that handles customer requests.

Cloud Router terminologyCloud Router terminology

• Hybrid Cloud is a type of IT infrastructure that brings together the company’s internal IT resources on the one hand and public clouds resources on the other.

• On-prem: Customer site hosting their IT resources and network equipment for connection to Yandex Cloud via Cloud Interconnect.

• Cloud network (VPC, Network): Virtual Private Cloud resource. A cloud network is used to provide network connectivity in all availability zones of a single region.

• Subnet: Virtual Private Cloud resource. It belongs to a cloud network. Each subnet has an IP prefix (CIDR). Each subnet is always linked to a single availability zone. Cloud resources are connected to a subnet.

• Routing instance (RI) is a resource you can use to create a specific network topology which may include:

  • IP prefixes of subnets belonging to one or more networks.
  • Private connections. The number of private connections depends on the network topology type.

• Routing is the ability to direct network traffic using the Cloud Router and Cloud Interconnect resources.

• VPC Stitching is one of the Cloud Router mechanisms providing network connectivity between cloud networks (VPCs) that are located in folders of the same or different clouds within a single cloud organization.

• Stitching announcements are aggregating routes implementing the VPC-Stitching mechanism. They are used to create individual types of network topologies to configure private connections. Regional in scope, they combine IP prefixes of subnets across all availability zones. Stitching announcements are calculated and added to the private connection configuration by the client. Stitching announcements are not automatically calculated or added to the private connection configuration on the Yandex Cloud side. You will find them displayed in the ipv4_static_routes field of the Cloud Interconnect API for private connections.
