Greetings,
Please note that there are participants from at least 14 countries apart from India that too within few weeks of announcement.

Surely the students and practiioners too will gain a lot.
I am planning to experiment and present CentOS as a robust High Availability Platform for Applications like KOHA/DRUPAL etc. I don't know what I will Land up with though over the course of time.
Some of the question I am looking at in a practical viewpoint of an Application and IT infrastructure Architect are:
1. We need to look at lifetime of the application like KOHA - perhaps 10 year in the timeline of a library? 2. Is the quick changing Fedora/Ubuntu stand the trial? 3. What is the interaction between DSpace etc? 4. Can they both be running in HA peacefully? 5. etc.
If so please reply on this list.
I must declare that I am not going to invest INR(Money) in this. I can't afford HA hardware at this point of time.
Would anybody like to join me in presenting a paper or experimenting?
Perhaps two different department can jointly decide to own one server each and bring it together for HA demo teaching purposes and then use it later individually or using the HA setup for themselves and to educate next gen of the students.
Regards,
Rajagopal

Please define your concept of High Availability - people have different ideas on these buzz words.

I think 10+ years is a reasonable time frame. Version upgrades surely but changing to some other package - the migration cost could be prohibitive.
- Is the quick changing Fedora/Ubuntu stand the trial?
Don't know what you mean by this. IMO anybody using Fedora as a server platform and that too in production ... I know people are doing it ... In one instance, I was forced to install a version of Fedora (which was no longer supported at that time) because the vendor's app was certified only on that version!
- What is the interaction between DSpace etc?
- Can they both be running in HA peacefully?
IMO, if ERP apps can run in VMs then Koha and DSpace can also run in respective VM.

What is HA hardware? Do you really need enterprise grade servers to demonstrate your Proof of Concept or present your paper? For a Proof of Concept this can be achieved with mid range desktop(s) that support Linux KVM. (system board + cpu cost 13-15K).
Would anybody like to join me in presenting a paper or experimenting?
I think it would be better if you first present an executive summary of your paper/experiment.

(High) Availability is an engineering concept with a precise definition; it shouldn't be called a "buzzword" or be left open to people's own interpretations :-)

Still it is better to be clear than assume that everybody else has the same understanding of the concept. The OP is looking for collaborators and interested parties should know the assumptions he is making and the direction he wants to go. A reference URL would be sufficient :)
