Many companies use cloud services to get required compute infrastructure such as virtual machines, block storages and load balancers from the cloud as a service. There are many cloud services from different cloud service providers offering different compute infrastructure. Also, the pricing models differ. Companies are thus faced with the challenge of modelling cost relevant compute infrastructure requirements as a request. There are many tools that can formulate cost-relevant compute infrastructure requirements as a request for cloud services. However, these tools are either limited to cloud services from one cloud service provider or lack of modelling support. Thus, to support modelling, a Graphical Compute Infrastructure Modelling Tool is presented in this thesis. With this tool, it is possible to model cost relevant compute infrastructure requirements as a request that is independent of the offer of one cloud service provider. Thereby, the Graphical Compute Infrastructure Modelling Tool improves the modelling in certain disadvantages of state of the art tools.
