I am looking into the idea of setting up 10 - 15 virtualized instances
of MySQL. The reason for this is as follows...we are going to be
setting up a 3 to 4 node MySQL replication cluster (1 master-rw and 2
slaves-ro)...each having 16 to 32 GB of RAM.
In order for our development team to do their work...they must have
access to some Mysql resources that are close to the production
environment. I am not currently in a position to provide each developer
two MySQL servers (one master and one slave with 16 to 32 GB of RAM) for
testing...or obvious reasons...mainly cost ;-)
So I have been thinking about how best to provide such resources, at
this point I am thinking that I can use OpenVZ to help me out a bit.
I was wondering if anyone had any thoughts on this issue...should I just
run 10 instances of MySQL on the same server...are there other options?
I am concerned with trying to ensure that the metrics, resources,
workloads, etc from these development servers has some sort of relevance
to our production environment...otherwise we are testing apples and
oranges...which the dev team will clearly point out...and in a way I
know we are...but I would like to minimize the effects....
Any thoughts?
Thanks in advance,
Shain
