Defining twelve-factor applications
The twelve-factor applications are a collection of good practices suggested for cloud-native applications. Applications that adhere to such a list of practices will most likely benefit from being deployed on cloud infrastructures, face web-scale traffic peaks, and resiliently recover from failures. Basically, twelve-factor applications are the closest thing to a proper definition of microservices. PaaS is very well suited for hosting twelve-factor apps. In this section, we are going to have a look at this list of factors:
- Codebase: This principle simply states that all the source code related to an app (including scripts, configurations, and every asset needed) should be versioned in a single repo (such as a Git source code repository). This implies that different apps should not share the same repo (which is a nice way to reduce coupling between different apps, at the cost of duplication).
Such a repo is then the source for creating...
