This has been getting better. The platform-specific knowledge necessary to get a Heroku app running on Cedar is pretty much limited to knowing you need to put "heroku run" in front of your rake tasks or command line utilities, and perhaps 3-4 sets of arguments to back up a database, restore one, and restart your app.

Compared to the amount of knowledge necessary to effectively and reliably run a dedicated server, it's honestly pretty trivial.

I've had to rewrite gems and Rails code to work properly with Heroku. The biggest drawback to Heroku IMHO is the read-only filesystem. It makes simple tasks like creating ZIP files on the server more challenging.

They've actually moved from a read-only to an ephemeral file system with Cedar. You can write to your hearts content, but can't really rely on the files being there. In most cases where you'd want to write files, you really should be using something like S3 anyway.

Heroku's Cedar stack does not have a read-only filesystem. However, it is ephemeral, meaning it is not durable and it's not a guarantee that things you put on the filesystem will stick around between requests.

This happened to me as well. If I had to do it all over again, I would have started pushing to Heroku from the start.
