The Mapbender project requests a dedicated VM on osgeo4, see at:
http://wiki.osgeo.org/wiki/Infrastructure_Transition_Plan_2010#osgeo4

The server should be known as http://mapbender.osgeo.org (which currently
redirects to http://www.osgeo.org/mapbender)

  * summary: VM on osgeo4 for the Mapbender project => VM on osgeo4 for
              Metadata Repository

Comment:

The summary of the ticket was changed to: "VM on osgeo4 for Metadata
Repository" to reflect the purpose of this instance. It is planned to use
this VM as a permanent OSGeo resource providing a service metadata
repository with monitoring and management capabilities. It is intended to
be used to rivive the currently dormant Public Geospatial Data Committee
Working Group on Geodata Discovery [1]. The Wiki page is simply not the
right tool to get things done, it was created and used well initially but
was abandoned when it grew too large to be useful.

It seems a more appropriate place for this might be on the webextra VM
which already exists or on a to be created Projects VM. Is this ticket
still connected to mapbender in any way?

Per our discussion today:

Since the Geodata Working Group is treated as a project of OSGeo, this
work is ideal for the projects VM. After the meeting today, we have
outlined the infrastructure for that VM, and will be getting it set up
shortly.

Once the projects VM is up, access will be granted to the users who
currently have access to the Telascience blades (via ldap); the people
interested in setting up a Metadata repository can collaborate to get the
software that they want installed and running on that machine.

Comment(by arnulf):

As an OSGeo-service (just like SVN, Trac or Wiki) metadata.osgeo.org has
high availability requirements. Parking it on a general "projects VM" is
asking for trouble. The load requirements are minimal compared to that of
a build bot or large SVN commits as it only moves around URLs and other
metadata.

A reliable linkage to OSGeo's LDAP is required.

Arnulf:

"OSGeo-service" only has meaning if SAC takes on that role. You have
outlined it as:
  * A replacement for mapbender.osgeo.org
  * A project of the Geospatial Data group
  * An OSGeo-service

OSGeo services are software services that SAC has taken on the task of
installing and maintaining. Since metadata.osgeo.org has, so far as I can
tell, not been described to SAC, there is no way that SAC could take on
the task of maintaining the software in question.

At this time, SAC is happy to leave the operation of the metadata service
up to the Public Geospatial Data project. If you wish to propose that SAC
takes on the running of a metadata repository as a foundation task (not as
a project task), then a more concrete proposal sent to the mailing list is
probably the right way to handle that.

As to your concerns about load/availability: The VM ('hardware') provided
for the metadata project, while shared with the other projects, is the
best-provisioned hardware that OSGeo has thus far made available; it has
been given the most disk space, CPU, and RAM of any VM that we make
available. It is the most important VM for OSGeo to maintain for public-
facing purposes, outside of the Drupal VM (for osgeo.org). Additionally,
the connection to OSGeo's LDAP is exactly the same for all of the OSGeo
services running on the VMs hosted at OSUOSL, so the projects VM is not
special in that regard. (This includes the main drupal site, SVN, Trac,
etc.)

If the projects VM is crowded, it will be SAC's responsibility to help
affected services move to other hosts, and we have already set up
monitoring of the services in question to ensure that we can observe and
be proactive in moving these services. If the projects VM is overloaded,
we will be happy to help migrate services to another VM; until such time
as a service demonstrates a need for a seperate host, it is our intention
to maintain most projects sharing infrastructure, maintained in
combination with SAC.

To sum up: If you want SAC to maintain it, you need to propose that to
SAC. (The answer may be 'no'; SAC is already completely overloaded with
the existing responsibilities, and adding more without more resources is
unlikely to happen.) IF you want the Geodata group to maintain it, then it
is in the right place, and if it turns out that it's the wrong place, SAC
will gladly help change that.

Comment:

Arnulf,

Per discussions on the sac mailing list OSU OSL has created a new "adhoc"
VM. This should be suitable for use by the Mapbender SoC student for
development purposes. It is accessable at:

   adhoc.osgeo.osuosl.org

Anyone in the telascience LDAP group will have ssh access, and can use
this url to add new people:

   https://www.osgeo.org/cgi-bin/auth/ldap_shell.py

Furthermore, I have given you sudo access, and you can grant sudo access
(by adding people to the sudoers group in /etc/group) as needed on this
system.

I have written up some notes at http://wiki.osgeo.org/wiki/AdhocVM

Note that the core mapbender website (http://mapbender.osgeo.org) is still
likely best hosted on the main Projects VM - intended for stable, mission
critical services.

Thanks for making this possible, it is greatly appreciated! My timing is crappy, I will be off line myself for the next three weeks but I guess that the Mapbender team will eagerly start off right away.

Thanks,
Arnulf.
