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 the public cloud, you share physical server resources with other clients. To set up an infrastructure isolated from other clients, use VMware-based private cloud.
To work with the public cloud, you need to create an organization in one of the regions: Moscow or St. Petersburg. A virtual data center is created in one of the clusters in the selected location. For the Gold cluster, a multizone solution is available: deployment across two availability zones within a region at once.
Once a virtual data center is created, its resources are managed through the Cloud Director panel.
By default, Selectel basic DDoS protection is enabled for the public cloud.
If you need help administering the public cloud, order the Managed Services service.
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;
- VMware vSAN™ — storage for virtual disks and catalogs;
- VMware Cloud Director® — control panel for virtual data centers.
Clusters
The cluster is selected when creating a virtual data center. After creation, you can view the cluster where a specific virtual data center was created.
All clusters use:
- high-performance NVMe SSDs;
- Juniper Networks and Brocade network equipment;
- virtualization hosts on VMware HCL certified hardware platforms.
Virtual data center link bandwidth is 1 Gbps.
* The cluster is no longer available for order.
** The write speed for disks is specified as the total across all operations in 32 KB blocks.
View cluster type
After creating a virtual data center, you can view the cluster where a specific virtual data center was created:
-
in the control panel: in the top menu, click Products and select VMware-based Cloud → Virtual Data Centers section → check the cluster name in the middle of the cluster card. For example, Platinum-2 means version 2 of the Platinum cluster;
-
in the virtual data center name. You can view it in the control panel in the Virtual Data Centers section and in the Cloud Director panel on the Data Centers → Virtual Data Center tab. The name is specified in the format
s-xxxx-location-cluster-vDCxx, where:s-xxxx— organization name;location– location, for example MSK1;cluster— cluster version, for example G1;vDCxx— virtual data center number.
VMware NSX
Full VMware NSX® functionality is implemented for network virtualization. NSX enables flexible configuration of local and public networks and supports:
- network micro-segmentation using stateful Distributed Firewalls with support for all protocols;
- separate Network Address Translation (NAT) rules by source and destination IP address, port forwarding;
- DHCP protocol for configuring IP pools, gateways, DNS servers, and search domains;
- creation of VPN connections based on IPsec, SSL VPN, and L2 VPN standards;
- L4/L7 application load balancing with dynamic configuration of virtual IP and server pools;
- dynamic routing, BGP and OSPF support for configuring complex networks and network interconnectivity between locations.
Multizone Gold cluster
When choosing a multizone solution, along with creating a virtual data center, a virtual machine cluster is reserved in an additional data center (VMware Stretched vSAN technology). The virtual data center is regularly replicated to the backup cluster, and the availability of both the primary and replicated data centers is continuously monitored.
In the event of virtual data center unavailability, all virtual machines will automatically start on the backup data center with minimal downtime.
