Yeah, I tend more and more to be annoyed by some devs negativity every time someone is trying something new. I may take that personally, yes, not about docker and microservices, but because I'm always told to stop creating and use what already exists each time I'm trying to develop a new concept on sideprojects. I have to let that go, I guess.

Thanks for the article, a lot of interesting things in it.

It's funny how it's focused on the scaling problem. It may depend on which circles we're in, but it seems to me that what people were most interesting about in heroku was more the ease of deployment than the scalability. It probably depends on the size of your usual projects.

Yet, what is interesting in docker is not just scalability. I find it way easier to code system dependencies with docker than with chef, that's already a big win. Also, I've stayed out of heroku for my own projects, mainly because of the cost. Docker, with dokku, allows me to have the same comfort one have on heroku, but with a 80€/mo server (handling about 15 small apps, and still having one third of memory available). And having several applications using several versions of ruby or postgres on the same server is not a problem anymore.

In that regard, docker is not only interesting for people who have massive infrastructure to manage, but also to people who are used to self hosting and want an easier way to deliver.
