I was going to say "If your Aunt had balls she'd be you Uncle" but I 
don't want to be accused of being transphobic again :-(

Suffice it to say I don't want and never asked to "grow to Google scale".

I have a PaaS cloud service in Sydney, another in Melbourne a an 
arbiter/quorum instance in Singapore. I keep a minimum of 3 Application 
Web Servers and 2 Database servers running in Melb, Syd but can grow to 
10 each if load increases.
