This work package includes the design of the entire BayernCloud reference architecture. The reference architecture integrates the results of the reference building blocks from the technical architecture, the business model, the governance model and the certification model. The reference architecture follows the structure of the 4+1 model according to Kruchten and combines the use cases of BayernCloud in 4 views.

Using the BayernCloud reference architecture, concrete industry-specific architectures and sub-components can be derived. The overall reference architecture serves as a blueprint for the instantiation of digital platform ecosystems and can be used for both scientific and practical purposes.
