SAPS comprises 5 components (a Dashboard, a submission dispatcher, a scheduler and an archiver). The user interacts with the system through the Dashboard, a web-based GUI that serves as a front-end to the Submission Dispatcher. After successfully logging in, the user can specify the region, the period that he/she wants to process, as well as the Energy Balance algorithm to be used. The execution consists of three-stages: input download, input preprocessing, and algorithm execution. With this data, the Dashboard creates the processing requests of each single scene and submits them to the Submission Dispatcher, which creates a task associated with the request in the Service Catalogue database (PostgreSQL).
The users can access the production instance by registering in the SAPS VO through the link https://operations-portal.egi.eu/vo/view/voname/saps-vo.i3m.upv.es. Additionally, a user can automatically deploy its own instance, which is configured and managed by EC3. All the SAPS components run on a K8s cluster, and the only component that needs to run in the front machine is the Dashboard, so it can be exposed using the public IP of the front to the users.
