-This Service follows the following architectual design principles
-- horizontal scalability, be stateless
-- don't reeinvent the wheel, use libraries
-- start testing early, keep 100% code coverage
-- keep it simple stupid (kiss), few files, few sloc, no stuff
-- high performance via non blocking asynchronous code

 ## Security

 The API (PDF generation) is secured by an api token and can therefore be public hosted. The metrics, status and documentation are not protected by the api token (disable or protect them in case you need it). Keep in mind that you should always use https for communication with the service.
