mongos and config server on a 32bit machine?

[rbrc]

I'm wondering how bad of an idea it would be to setup mongos and the
config server on a 32bit machine. I recognize that the config data
would be limited to 2gb of data; is that enough space? The reason I
ask is because we host in EC2, and small and medium machines are only
32bit, and it seems like overkill to put mongos and the config server
on large machines.

Thanks.

A mongos on a 32-bit instance isn't great as it will use ram for
connections, merging data, etc...

You could try it - but a bit risky...

Many people deploy the mongos process directly on their app-servers or
client machine so they don't need a dedicated resource for it.

With journaling in 2.0.x+ it is advisable to have more than 2 GB of
possible space so it is not suggested. You could turn off journaling
but that would lead to higher chance of data corruption/loss
potential. I would suggest against doing that if you can avoid it. You
could try it out and see if you feel comfortable with it.

So realistically mongos needs more than 1.7gb of ram?

There are lots of factors, but it could.
