= VCL Proposal =

A proposal to the Apache Software Foundation Incubator PMC by

Matt Hogstrom^*^, Aaron Peeler^#^, Mladen Vouk^#^

^*^IBM, ^#^North Carolina State University

September 6, 2008

== 1. Abstract ==

VCL is a management framework for building, dispensing and managing virtual machine images
across a set of bare metal machines or systems with an installed virtual machine hypervisor.

== 2. Proposal ==

This proposal seeks to create a top-level Apache Software Foundation project to continue the
development and advancement of the Virtual Computing Lab open-source framework.  This project
is primarily concerned with providing a framework for hosting virtual server instances.  These
instances can contain a variety of application types.  This implementation is in use at North
Carolina State University to facilitate efficient use of their computing infrastructure using
virtualization technologies.   It has broad backing from the existing contributors to the
North Carolina State University Virtual Computing Lab as well as interest from a variety of
outside organizations.

We thank you for your consideration.

Key Features & Goals
 *  A REST driven framework for managing virtual computing resources.
 *  Scheduling server resources in a virtualized environment to improve hardware and software
 *  Expand supported hypervisors to include additional machine architectures.
 *  Security support for multiple roles in managing and gaining access to Cloud resources.
 *  Tools to create images to be hosted in the virtual infrastructure.

== 3. Rationale ==

The current implementation of the Virtual Computing Lab provides benefits for NC State University
in terms of efficiently managing hardware and software resources.  It also improves the simplicity
to distribute images to a wide variety of users in a simplified way thus increasing human
productivity in the process.  Although originally focused on academic usage the infrastructure
to manage the virtual assets have broader applicability for general data processing needs.
 To explore these additional areas NC State wants to bring this project to a more general
population of developers and users to expand the usefulness of the codebase.

In addition, this technology would benefit many organizations that are looking to manage a
set of physical assets through the application of virtual server and image management.

== 4. Need for a Community Effort ==

The VCL project at NC State has been very successful at serving the needs of the academic
community and their unique needs for image creation, dispensing, usage and scheduling.  To
enhance the system for broader applicability for hosting other workload types and incorporating
a diverse set of ideas and driving towards a more generalized approach there is a need for
developers from commercial, academic and other users to be involved in evolving the code base.

== 5. Known Risks ==

''Commitment to future development.'' NC State has been actively working this code base with
other universities since 2004.  Enhancements are needed as the world of cloud computing evolves.
 The initial commiters listed are actively working on the code base and have a list of desired
enhancements included later in this proposal.

''Experience with open source.'' Some of the developers have had limited involvement in open
source projects.  They understand that collaboration at Apache is community oriented.  Working
with mentors and others at Apache to build a solid community around the code base is an understood
goal of the project.

''Diversity of developer community.'' The initial code base was developed at NC State over
a few years with involvement with some local universities.  There has also been interest and
some participation from corporate interests.  The initial community is made up of individuals
from 5 universities and one corporation.

''Relationship to other Apache projects.'' There are no Apache projects such as VCL is currently
involved with although the project uses releases from projects such as HTTP. Recent proposals
such as Tashi have similar goals but not necessarily complete overlap.

== 7. Source ==

The seed code from NC State has been in production since 2004 and has undergone several changes
over that time.  It currently serves the needs of the Virtual Computing Lab in use at NC State
as well as other universities in various stages of exploitation.

Access to existing source code can be found here for those interested in looking at current
project status:
