Public Cloud powered by VMware product description

Public Cloud powered by VMware is a cloud infrastructure based on the VMware vSphere® and VMware Cloud Director® (formerly vCloud Director®) platforms, which is provided on Selectel's physical infrastructure (IaaS).

In a public cloud, you share physical server resources with other clients. To organize an infrastructure isolated from other clients, use a private cloud based on VMware.

To work with a public cloud, you need to create an organization in one of the regions — Moscow or Saint Petersburg. Within an organization, a virtual data center is created in one of the clusters in a specific availability zone of the selected region. For the GOLD-1 cluster, a multizonal solution is available — deployment across two availability zones within a region.

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

By default, basic Selectel DDoS protection is enabled for the Public Cloud.

If you need help administering your public cloud, order the Managed Services.

Tasks solved

expanding cloud capacity hosted in On-Premises infrastructure without additional hardware costs;
moving public applications to a separate cloud;
creating disaster-resilient infrastructure by using a public cloud as a backup;
launching a test environment in minutes.

Technologies

VMware NSX® — network virtualization;
VMware vSphere® — application virtualization:
- version 8.0 U3 — for the AMD HiFreq-1 cluster;
- version 7.0 U3 — for other clusters;
VMware vSAN™ — virtual disk and directory storage:
- version 8.0 U3 — for the AMD HiFreq-1 cluster;
- version 7.0 U3 — for other clusters;
VMware Cloud Director® (version 10.5) — Virtual Data Center Control Panel.

VMware NSX

For network virtualization, the full functionality of VMware NSX® is implemented. NSX allows for flexible configuration of private and public networks and supports:

network micro-segmentation using stateful Distributed Firewalls (Distributed Firewalls) with support for all protocols;
separate address translation (NAT) rules for source and destination IP addresses, port translation;
DHCP protocol for configuring IP address groups, gateways, DNS servers, and lookup domains;
creation of 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 (Dynamic Routing), BGP, and OSPF support for configuring complex networks and inter-location networking.

Platinum-1	Intel® Xeon® Gold 6254 @ 3.10 GHz	Cluster based on All-Flash vSAN: vSSD (5000 IOPS); Fast vSSD (25000 IOPS); Ultra vSSD (40000 IOPS)
AMD HiFreq-1	AMD EPYC™ 9275F @ 4.10 GHz	Cluster based on All-Flash vSAN: vSSD Pro (10000 IOPS); Fast vSSD (25000 IOPS); Ultra vSSD (40000 IOPS); Extreme vSSD (80000 IOPS)

The write speed for disks is listed cumulatively for all operations in 32 KB blocks.

All clusters use:

high-performance NVMe SSDs;
Juniper Networks and Brocade networking equipment;
virtualization hosts on hardware platforms certified for VMware HCL.

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

Multizonal Gold-1 cluster

When choosing a multizonal solution, a virtual machine cluster is reserved in an additional data center alongside the virtual data center (VMware Stretched vSAN technology). The virtual data center is regularly replicated to the backup cluster — the 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.
