. *SIT-Web-FE* - This component (SPA with Angular) provides two HTML pages: a table and a map
with failure information. This component is in the DMZ and can be called up from the Internet.
-. *SIT-Web-Guard* - The SIT-Web-Guard (Java Spring Cloud) is a Zuul proxy
-(API gateway) that only forwards explicitly configured services. For the failure information
-tool, only certain services are available on the Internet that do not require authentication.
-Since the SIT-BE is protected by Spring Security, the SIT-Web-Guard procures guest authentication for forwarding.
+. *SIT-Web-Cache-Service* - The SIT-Web-Cache-Service is a service which receives the published
+grid failures in the form of a JSON from the SIT-BE and makes them available to the SIT-Web-FE
+via a ReST interface. This component is implemented with Angular / Typescript. Because this
+component is only equipped with freely accessible data, no security is necessary here. The
+SIT-Web-Cache-Service, like the SIT-Web-FE, is situated in the DMZ.
. *SIT-FE* -
This component (SPA with Angular) provides the user interface for the failure information application. The SIT-FE
receives its authentication when it is called from the PortalFE in the form of a JWT.
. *SIT_BE* - The SIT-BE (Java Spring Boot Microservice) provides all CRUD services in the form of
-ReST services that the two frontends require. The SIT-BE is the only component that has
+ReST services that the frontend requires. The SIT-BE is the only component that has
access to the database. Every call is authorized against the PortalBE. This microservice also includes
the JobManager subcomponent.
. *JobManager* - The various imports and exports are controlled via the JobManager. The JobManager
