I would love to use Heroku/PaaS the one thing holding me back is my service needs a proper file system with a highly customised server for the compilation of LaTeX documents (https://www.sharelatex.com https://www.sharelatex.com). I would also prefer to use an Linode server but because I rely heavily on s3 and the aws based MongoLab I am using an ec2 for the moment. If the service gets bigger I am planning on leaving the LaTeX compiling on the ec2 and moving everything else into Heroku, but thats a big if. One thing I would say to other small timers like me who can't use a PaaS for some reason, automate your deploys as much as possible, capistrano is a good start https://github.com/capistrano/capistrano/wiki https://github.com/capistrano/capistrano/wiki . Also look through the list of Heroku addons for other services to make life easier, I use MongoLab and Loggly for starters.
