The following diagram shows the overall architecture on our infrastructure which can be used as a blueprint for other deployments - the architecture is based on the network zone policy concept of the Federal IT Steering Unit (FITSU, https://www.isb.admin.ch/) - Official Document.

The backend services for the CovidCode App are hosted on the following Federal Office of Information Technology, Systems and Telecommunication (FOITT) Atlantica Cloud Components:

CAP = SUSE Cloud Application Plattform (Coud Foundry)

CaaSP = SUSE Container as a Service Plattform (Kubernetes)

Internally we differentiate between the black and the red system. The black system is on the left side and is the system used by the health authorities (HA - mostly doctors) developed by FOITT (https://www.bit.admin.ch/bit/en/home.html) and descibed in this repository (admin-ch).

CAZ = Central Access Zone

SSZ = Shared Server Zone

The general flow between the black and the red system is shown in the following diagram:
