The core components that encompass VDI-in-a-Box are:
VDI-in-a-Box 5.1 Broker
●
o Installed on servers either in the data center or branch office, the broker
authenticates users, manages the assembly of users‖ virtual desktop
environments and brokers connections between users and their virtual
desktops.
Provisioning Service
●
o Enables and controls dynamic provisioning and de-allocation of virtual
desktops.
High Availability
●
o vdiManager instances on physical servers communicate with each other to
share key operational and configuration information. When a physical
server fails, the remaining servers in the grid have the needed information
to create extra desktops to replace those on the failed server. When the
failed server is repaired and re-joins the grid, the key operational and
configuration information is sent to it and it then resumes desktop
provisioning.
Load Balancing
●
o Desktops are created across servers running vdiManager based on how
many desktops are currently running on each server and the availability of
computing resources (memory and cores) on each server. When a user
logs on, vdiManager provisions a desktop from a lightly loaded server.
Virtual Desktop Agent
●
o Installed on virtual desktops, the agent enables direct ICA (Independent
Computing Architecture) connections between the virtual desktop and
users‖ endpoint devices.
Template Management
●
o Virtual desktops are created from templates. Templates consist of:


Citrix Desktop Receiver
●
o Software running on an endpoint that enables the device to connect to a
virtual Windows XP, Vista or 7 desktop running on a server
Additional VDI-in-a-Box components
●
o Hypervisor Integration. The Citrix VDI-in-a-Box solution can be used in
conjunction with Citrix XenServer or Microsoft Hyper-V for the provisioning
of virtual machines.
o Active Directory Integration. VDI-in-a-Box optionally uses Active Directory
for security services like authentication.
o Antivirus Management - An optional component that is not built into the
solution but is highly recommended.
