Yes, sure. There's more benefits to reap: You can intermingle your services with services bought/rented somewhere and eventually replace the ones you're using if it pays of at the scale you reached (think redis2go vs. a self-hosted redis server) Services usually offer good boundaries at which you can separate the system and scale over multiple machines as well as a good entry point for black box testing.
