I tend to agree with this approach specially given how much ram/cores you can get on a single box today. You can run what took a cluster of servers 10 years ag

I tend to agree with this approach specially given how much ram/cores you can get on a single box today. You can run what took a cluster of servers 10 years ago on a single box. Just make sure your code doesn't assume that everything is running on the same host. Use some logical names that map out to an actual host, db_write -> 127.0.01 and hopefully later db_write -> db123.cloudfoo.net
