The options for hosting ruby web application are plentiful, all with different advantages and disadvantages, options, limitations. How to start, how to grow, what are the pitfalls? With this talk I’d first like to give a short overview of several cloud hosting alternatives such as plain VPS, AWS, EngineYard, Heroku, and provide some insights based on my experience with them – beyond just somehow getting it to run, but also how to handle continuous deployment, how to maintain and scale them. While Rails already comes with many best practices build in, there are still plenty enough traps for you. We definitely had our fair share, and I’d like to share some of them for your entertainment and learning.
