Open Stack

Hi everyone,

In Shanghai we held a forum session to gauge interest in a new SIG to 
specifically address cluster scaling issues. In the past we had several 
groups ("Large deployments", "Performance", LCOO...) but those efforts 
were arguably a bit too wide and those groups are now abandoned.

My main goal here is to get large users directly involved in a domain 
where their expertise can best translate into improvements in the 
software. It's easy for such a group to go nowhere while trying to boil 
the ocean. To maximize its chances of success and make it sustainable, 
the group should have a narrow focus, and reasonable objectives.

My personal idea for the group focus was to specifically address scaling 
issues within a single cluster: basically identify and address issues 
that prevent scaling a single cluster (or cell) past a number of nodes. 
By sharing analysis and experience, the group could identify common pain 
points that, once solved, would help raising that number.

There was a lot of interest in that session[1], and it predictably 
exploded in lots of different directions, including some that are 
definitely past a single cluster (like making Neutron better support 
cells). I think it's fine: my initial proposal was more of a strawman. 
Active members of the group should really define what they collectively 
want to work on. And the SIG name should be picked to match that.

I'd like to help getting that group off the ground and to a place where 
it can fly by itself, without needing external coordination. The first 
step would be to identify interested members and discuss group scope and 
objectives. Given the nature of the group (with interested members in 
Japan, Europe, Australia and the US) it will be hard to come up with a 
synchronous meeting time that will work for everyone, so let's try to 
hold that discussion over email.

So to kick this off: if you are interested in that group, please reply 
to this email, introduce yourself and tell us what you would like the 
group scope and objectives to be, and what you can contribute to the group.

Thanks!
