The FlaggedRevs lab site mysteriously got better, which makes me
nervous. To counteract that, I'd like to put together some basic smoke
and load tests. My plan is to do that on Amazon's cloud infrastructure.
A few questions:
1. Does anybody have an AMI (basically, a virtual machine config)
that's already like WMF production servers?
2. If not, is there something like a Puppet config that I can use to
help build the AMI?
3. What's the best way for me to find out details on production
server configs? I see the info in Special:Version, but I'm
wondering a) where to find those packages, and b) if there are
other requirements (e.g., particular kernel versions, supporting
Once I get the AMI working, I'll post details here so others can easily
spin up pseudo-production boxes.
I can only assume by this post that you're completely out of the loop
on FlaggedRevs and have received no support from Wikimedia tech staff.
There's no need for performance testing since we've been running it on
our second-biggest wiki for 18 months and the hardware requirements
there can be extrapolated to the English Wikipedia.
Domas tells me that that extrapolation leads to some concern that we
might approach our hardware limits on the s1 cluster. The sums need to
be done and the hardware ordered, if necessary.
I think we need to discuss this off list, preferably in real time with
Aaron and Domas.
