This topic contains the following sections:

Virtualization

Creation of a virtual version of a resource or device, for example, a server or a storage device.

EPAM Cloud is a platform for creating, running and managing virtual machines emulating certain computer systems and executing applications similarly to physical computers.

VLAN

Virtual Local Area Network, Group of hosts sharing a single set of requirements and acting as if connected to a common broadband domain, regardless of their physical location.

VMware

VMware is a US company offering virtualization software and services. VMware is considered to be the first company to ever provide virtualization services.

VMware virtualization products are used in the EPAM Cloud Orchestration Framework.

VMware ESX and VMwareESXi serve as hypervisors creating and running the virtual machines in EPAM Cloud.

The centralized management of the hypervisors is performed by the WMware vCenter Server.

See Cloud Orchestration Framework page for details.

Visit VMware Official Website for details on VMware products and services.

VNC

Virtual Network Computing, a graphical desktop sharing system used to control another computer remotely using the keyboard and mouse. The keyboard and mouse events are sent to the other computer over a network and the related graphical screen changes are sent back.

Volume

Storage memory available in a virtual machine by default (system volume), or additionally attached to it.

Each Windows VM initially has 100 GB of storage volume, and each Linux VM - 40 GB of storage volume. Additional volume can be created, if necessary, and attached to the VM. Additional volumes can be increased, detached from VMs, attached to VMs again, and deleted when no longer needed.

Additional volume is charged on the hourly basis per GB of the used storage volume. Storage volume is charged on stopped instances, too, however, the charge is lower than that for running instances.

See the Maestro CLI User Guide, Section 7, Working with Volumes, for details.

Vulnerability

Cloud infrastructure flaw which may result in compromising of confidentiality, availability or consistency of EPAM Cloud assets.

Vulnerabilities detected in the system are categorized as critical, high or medium according to the severity of security risk they may pose. The severity level is evaluated by the system and stated in the weekly security report.

EPAM Cloud Security Policy establishes the following deadlines for resolving vulnerabilities:

  • Critical: 30 days
  • High: 60 days
  • Medium: 60 days

See Security Policy for details.
