HiSea backend architecture guidelines

Summary
Currently the existent backend platforms (including the ones being proposed here FEWS and AQUASAFE) work in more “traditional” workstation environments. By moving to a cloud based system will need some adjustments in the overall architecture, but will allow moving to the next level of micro services concept based on docker containers. This approach will make the platforms independent of the infrastructure supporting an easy deployment in a cloud environment such as DIAS but also enabling the services to run in any type of operating system (Linux or Windows). This task will be focused on defining the backend design and assessing the required work to achieve this goal.
