Editing Linux Terminal Server Project (section)

== Scalability ==
Initially, the MILLE-Xterm project, funded by Canadian public agencies and school districts in the province of Quebec, created a version of LTSP integrating four subprojects: a portal (based on uportal), an open-source middleware stack, a CD with free software for Windows/Mac and, finally, MILLE-Xterm itself. The MILLE-Xterm project's goal was to provide a scalable infrastructure for massive X-Terminal deployment.{{Citation needed|date=March 2009}}

MILLE means ''Modèle d'Infrastructure Logiciel Libre en Éducation'' (Free Software Infrastructure Model for Education) and is targeted at educational institutions.

As of 2009, MILLE-Xterm was integrated back into the LTSP as LTSP-cluster, a project specializing in the large scale deployment of LTSP. One of the main differences between LTSP and LTSP-cluster is the integration of a web-based central control center that replaces the traditional "one configuration file per thin client" as is the method of client customization through LTSP's lts.conf file in the main LTSP. LTSP-cluster allows organizations to centrally manage thousands of thin clients and their parameters from a central location.

In LTSP-cluster high-availability and high-performance thin-clients are specified through the optional use of redundant components. Services that can be load-balanced and made highly available are:
* DHCP server
* TFTP server
* Boot servers (root filesystem for the thin clients)
* Application servers
* Control center (PostgreSQL database + web frontend)<ref>{{cite web

LTSP-Cluster can support Linux application servers as well as Windows application servers and provides a similar level of support, centralized management, high-availability, and load-balancing features for both platforms.

Also included is support for virtual desktops for remote users using [[NX technology]]. The NX protocol can allow remote Windows and Linux sessions to be accessed from a web browser with very low bandwidth (40&nbsp;kbit/s) requirements and tolerance for high-latency connections. The NX client runs on various operating systems including Linux, Mac, and Windows.
