Roadmap to production

Roadmap to production

[Thomas Mueller]

hi 

reading http://ceph.newdream.net/roadmap/ leaves me with some 
questions. :)

* is there some roadmap when CEPH will be official announced "production 
ready" 
* and will there be commercial support for it?

These are good questions.  :)

I've made the Ceph site link directly into the redmine roadmap, where 
we'll be maintaining a detailed set of issues (features, bugs) for each 
upcoming release along with a target release date.  The roadmap now 
includes a v1.0, which will be something we at least will cautiously 
deploy in production.  I would like to get there (or close to it) by the 
end of the year.

I prefer to avoid "production ready" as that is a bit of a subjective 
term.  Different people have different stability requirements and 
expectations.  That said, I would like v1.0 to be something I am 
comfortable encouraging people to use in real (but non-critical) 
deployments.

> * and will there be commercial support for it?

Yes.  We haven't settled on exactly what form that will take (what the 
support contract terms will look like, whether there will be a 
semi-independent entity, etc.), but that will be settled once we get 
closer to v1.0.

answering here the question from another thread because IMHO it fits 
better:

as storage is a fundamental service there are for sure other "stable" 
demands than for a newsreader/mailclient/whateveruncriticalapp. 

I'll give it a try to describe my idea of stable:

- stable means promised features (http://ceph.newdream.net/about/) work 
reliable
- no workarounds needed to use these features
- (at least) in a series of stable releases (aka "1.x") i can upgrade 
without downtime
- in a series of stable releases a can do a rolling upgrade
- in a stable series there no design changes introduced

Also, maybe there should be a small check list for different usage
scenarios, like for example maybe
the most generic usage will be just a file storage, without needs for
snapshotting, dkms support, and other complicated stuff.

works/tested
- file storing and retrieving in ext3/4
- snapshotting works
- dkms
- usage
...

so those who'd need just a plain file store - would not afraid trying and using.
