The drive to deliver products faster is relentless. In response to this, we have sought to unburden ourselves of the complexity of managing supporting infrastructure and instead adopt serverless architectures. Success in this brave new world is far from guaranteed, designing apps that run in such environments and that can take advantages of platform features such as auto scaling requires a new set of design practices.

The Twelve-Factor App methodology (https://12factor.net/), distilled from the collective wisdom of engineers with the experience of developing and deploying hundreds of apps on Heroku, defines a set of best practices for authoring code targeting modern cloud platforms.

In this presentation we will look at what the Twelve-Factor App methodology is, explore the rationale behind each factor, and demonstrate how it can be applied in practice. By the end of the session you will understand what is required to build cloud native applications, and have the knowledge to deliver on these requirements.
