Public Cloud Powered by VMware Product Description

VMware-based Public Cloud is a cloud infrastructure based on the VMware vSphere® platform and VMware Cloud Director® (formerly vCloud Director®) that is delivered on Selectel's physical infrastructure (IaaS).

In a public cloud, you share physical server resources with other clients. Use Public Cloud powered by VMware to organize an infrastructure that is isolated from other clients.

To work with the public cloud, you need to create an organization in one of regions — Moscow or St. Petersburg. The organization sets up a virtual data center in one of the clusters in a specific availability zone of a selected region. A catastrophe-resilient solution is available for the GOLD-1 cluster — placing it in two availability zones at once within the region.

Once a virtual data center is created, its resources are managed through the Cloud Director panel.

The default public cloud is under DDoS Guard L3-L4 protection.

If you need help with public cloud administration, order Service Administration.

Tasks to be solved

  • Expand cloud capacity hosted on On-Premises infrastructure without additional hardware costs;
  • Moving public applications to a separate cloud;
  • Creating a disaster-resilient infrastructure by using the public cloud as a backup;
  • launching a test environment in minutes.


  • VMware NSX® — Network virtualization;
  • VMware vSphere® (version 7.0 U3) — Application Virtualization;
  • VMware vSAN™ (version 7.0 U3) — virtual disk and directory storage;
  • VMware Cloud Director® (version 10.3) — Virtual Data Center Control Panel.

VMware NSX

Full VMware NSX® functionality is implemented for network virtualization. NSX allows flexible configuration of local and public networks and supports:

  • micro-segmentation of the network using stateful Distributed Firewalls with support for all protocols;
  • separate address translation (NAT) rules for source and destination IP address, port translation;
  • DHCP protocol for configuring IP address groups, gateways, DNS servers, and lookup domains;
  • create VPN connections using IPsec, SSL VPN, and L2 VPN standards;
  • L4/L7 application level load balancing (Load Balancing) with dynamic configuration of virtual IP and server groups;
  • dynamic Routing, BGP, and OSPF support for configuring complex networks and inter-location networking.

The write speeds for the disks are listed cumulatively for all operations in 32 KB blocks.

All clusters use:

  • P-Series NVMe SSDs (a solution in Intel's server SSD lineup);
  • HGST Enterprise server HDD disks;
  • Juniper Networks and Brocade networking equipment;
  • virtualization hosts on Intel® hardware platforms.

The bandwidth of the virtual data center channel is 1 Gbps.

Catastrophe Resilient Cluster Gold-1 (DR)

If you choose a disaster-resilient solution, along with the creation of a virtual data center, a cluster of virtual machines is reserved in an additional data center (VMware Stretched vSAN technology). The virtual data center is regularly replicated to the backup cluster — availability of the primary and replicated data center is constantly monitored.

In case of virtual data center unavailability, all virtual machines will be automatically started on the backup one with minimal downtime.
