 Title: Apache VCL
 <a name="ApacheVCL-ApacheVCL"></a>
 # Apache VCL

 The Apache VCL project.

 VCL, Virtual Computing Lab. The VCL can be many things, first and foremost
 it is a open-source system used to dynamically provision and broker remote
 access to a dedicated compute environment for an end-user. The provisioned
 computers are typically housed in a data center and may be physical blade
 servers, traditional rack mounted servers, or virtual machines. VCL can
 also broker access to standalone machines such as a lab computers on a
 university campus.

 One of the primary goals of VCL is to deliver a dedicated compute
 environment to a user for a limited time through a web interface. This
 compute environment can range from something as simple as a virtual machine
 running productivity software to a machine room blade running high end
 software (i.e. a CAD, GIS,statistical package or an Enterprise level
 application) to a cluster of interconnected physical (bare metal) compute
 nodes.

 Also using the scheduling API it can be used to automate the provisioning
 of servers in a server farm or HPC cluster.

 # Conceptual Overview

 The conceptual overview below shows that remote users connect to the VCL
 Scheduling Application (the web VCL portal) and request access to a desired
 application environment. The application environment consists of an
 operating system and a suite of applications. The computer types are
 machine room blade servers, vmware virtual machines, and standalone
 machines.
