Presentation: Tweet"Immutable Infrastructure: Kiss your Pets Goodbye, Here Comes the Cattle"

App deployment and server setup are complex, error-prone and time-consuming. They require OS installers, package managers, configuration recipes, install and deployment scripts, server tuning, hardening and more. But... Is this really necessary? Are we trapped in a mindset of doing things this way just because that's how they've always done?

What if we could start over and radically simplify all this? What if, within seconds, and with a single command, we could wrap our application into the bare minimal machine required to run it? What if this machine could then be transported and run unchanged on our laptop and in the cloud? How do the various platforms and tools like AWS, Docker, Heroku and Boxfuse fit into this picture? What are their strengths and weaknesses? When should you use them?

This talk is for developers and architects wishing to radically improve and simplify how they deploy their applications. It takes Continuous Delivery to a level far beyond what you've seen today. Welcome to Immutable Infrastructure generation. This is the new black.
