Provisioning Cloud Computing solutions is a tedious and long process, especially when configuring many components and not only offering the application but also the infrastructure. Today, an administrator has to upload, install and configure all the components of a software solution manually, which not only takes time and is prone to errors but also increases the \textit{onboarding costs} at the cloud provider. Decreasing deployment times by the use of an automated system is favored.

\textit{TOSCA} provides a specification which allows the deployment and management of cloud services by providing a meta-model. %With that it is possible to mitigate all problems in theory. \textit{OpenTOSCA} is a framework called \textit{container}, which can interpret the TOSCA specification and is used in this work to deploy an \textit{Enterprise Content Management} stack on a cloud environment, testing the boundaries of its capabilities. After designing deployment models by the means of a \textit{domain specific modeling} approach, an implementation is realized and compiled into a deployment file. This file is also called a \textit{container file} and is processed by OpenTOSCA to initiate the deployment on the cloud environment, including the necessary middleware.

The goal of this diploma thesis is to develop a TOSCA Service Template, that provides a topology model and automates the deployment of ECM core components. TOSCA Node Types for the middleware and application components have to be defined. To further help modeling the topology, a \textit{domain specific model (DSM)} will be introduced by generically defining all components and their operations. That generic model will be used to realize the actual ECM stack components. The ECM stack is then deployed via OpenTOSCA and the execution is reviewed.
