Introduce Storage Guideline #8
Description
As most of the stuff created is containerized, a stateless system is needed. If persistent storage is required, there should be guidelines on what to use when. For example, user data and the like should be stored in some form of database. Blobs should be stored in S3, and only temporary files, like cache files and intermediate files, can be stored in some form of temporary folder inside the container or the host.
