=== Solution Strategy
-The module 'Contact Base Data' bases on a three-tier architecture:
-
-. *Frontend* - The GUI is implemented as a web-frontend with rich-client functionalities.
-. *Backend* - The business functionalities are implemented in the backend tier. It provides the business functions via RESTful Webservices.
-. *Database* - The database stores all module specific data.
+The module 'Grid Failure Information' bases on a small microservice architecture, including
+an asynchronous messaging system.
== Building Block View
=== Whitebox Overall System
-The module 'Contact Base Data' contains two components (see figure 2):
+The module 'grid failure information' contains several components:
-. *UI* - Represents the graphical user interface and consumes the services from the business logic component via RESTful webservices.
-. *Business Logic* - Realizes the business functionality and the data storage of the module. The
-module itself is split up in several components due to the requirement to use
-microservices.
+. *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-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
+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
+knows all available import and export jobs and can control them via the internal message bus
+(RabbitMQ internal). Because the communication between the JobManager and the jobs takes place
+via the message bus, the JM does not need to know their configuration and URLs. For this, the JM must
+ensure synchronization (incl. timeout behavior) for asynchronous message communication.
+. *Import- and export jobs* - All jobs provide a uniform (MessageBus) interface to start a job,
+return the result of a job, or to provide information about the respective job (name, version, timeout, status, etc.).
+The job manager cyclically requests all configured jobs to send current status information to it.
+The interfaces of the individual jobs "outside" can be very different (file system, Internet, message queue, etc.)
