What the buyer wants

In 2019, on behalf of the Ministry of Education, Youth and Sport (hereinafter MBJS), a complex IT infrastructure was established on the basis of the products Univention UCS and Univention UCS@School, consisting of a central identity management system, hereinafter referred to as IDM, and the groupware and e-mail solution Open Xchange from the manufacturer of the same name, hereinafter referred to as OX. An extensive communication solution was created for 20,000 teachers at publicly owned schools in the state of Brandenburg. The schools depicted in UCS and UCS@School in the form of separate school OUs form the basis for the contexts set up in OX. Each school is thus assigned to a separate context in OX. The creation, modification and deletion of accounts in the IDM takes place via the technical procedures developed by the MBJS. After several years of operation, due to the lifecycle of OX, it is necessary to switch to the current version 8. The change to OX 8 requires extensive changes to the UCS OX connector and the IT infrastructure. The OX 8 version requires Docker runtime environments that do not exist with the existing IT infrastructure. It is not possible to simply update the software in the existing system. The MBJS therefore intends to allow the groupware and e-mail solution for teachers based on OX to operate as a SaaS solution by a provider in the future. The user accounts in the existing IDM should continue to form the basis for the e-mail inboxes and the existing provisioning processes should be maintained. Only the mail stack of the existing IT infrastructure is to be replaced by a SaaS solution.

Der Gegenstand dieser Ausschreibung umfasst die Beschaffung einer SaaS-Lösung, welche verschiedene Funktionen und Leistungen umfasst. Dabei liegt der Schwerpunkt auf der Bereitstellung einer umfangreichen digitalen Kommunikationslösung auf Basis von OX 8. Das MBJS sucht nach einem erfahrenen Auftragnehmer, der in der Lage ist, eine entsprechende Lösung auf Basis von OX 8 bereitzustellen und dabei die spezifischen Anforderungen und Bedürfnisse einer Landeslösung für das Land Brandenburg in punkto hohe Sicherheitsstandards (BSI Grundschutz), Datenschutzkonformität (DSGVO), Integrität, Flexibilität und Skalierbarkeit zu erfüllen.
