vCenter Indexing#

An automated system is registered with the vCenter Server to receive vCenter event notifications. These notifications are used to determine when new Virtual Machines are created in RPC-VMware to make them available for GOSS enrollment. The system also detects Virtual Machine configuration changes and when Virtual Machines are deleted.

CMDB#

Rackspace maintains a CMDB with details about your RPC-VMware environment. The CMDB is automatically updated with information about the Virtual Machines that you create in your RPC-VMware environment. The CMDB received additional updates when you enroll a Virtual Machine in Guest OS Services.

Guest OS Services Automation#

Rackspace has created custom automation services to provide the automated experience for Guest OS Services. This service orchestrates the interactions between all systems involved in providing Guest OS Services for your Virtual Machines.

vSphere Guest APIs#

Initial OS access during the enrollment process makes use of the vSphere APIs for guest actions which requires VMware Tools to be installed and running within the guest OS. This is used to validate the OS credentials provided with the enrollment and to ensure that the OS meets the requirements for enrollment.

MyRackspace Portal#

The MyRackspace portal will display your indexed Virtual Machines under the "Devices" section. This portal is also used when you enroll your Virtual Machines in Guest OS Services as well as create or interact with support tickets relating to these systems.

IPAM#

Rackspace uses an internal IPAM service to keep track of as well as allocate IP addresses within your RPC-VMware environment. During the automated enrollment process, the IPAM service will record the local IP address that you have assigned within the Virtual Machine and will provide a public IP address and record the NAT relationship.

Firewall#

Rackspace uses an automation system to perform certain configuration changes to your firewall. These changes are limited to adding or removing NAT's on your firewall during the automation processes for Guest OS Services.

Ansible#

During the automated enrollment process, an Ansible system is used to remotely execute specific OS actions to perform the required operating system modifications.

vCenter Network Interactions#

Rackspace automation systems interact with the vCenter server in your RPC-VMware environment over a secure connection using a service account that accesses various functions of the vSphere API.

Direct interactive access of the vCenter Web UI will be used to provide OS services. This includes observing performance details or accessing the console.

Virtual Machine Network Interactions#

During the enrollment process and at various times after enrollment, the OS of enrolled VMs is be accessed by Rackspace System Administrators and/or Automation Systems to perform actions within the guest operating system. The network access method for enrolled VMs uses dedicated individual public IP addresses added to the public interface of your hosted firewall. The public IP is NAT'd to the local IP address of the enrolled VM operating system.

Depending on the OS type of your Virtual Machine, Rackspace uses various secure network protocols such as ssh, WinRM, and RPD to access the OS.
