    This section shows the implementation of the concepts applied to a reference \gls{hybrid_cloud} model.
    It serves as an evaluation of the concepts on a technical level and as instrumentation for computing the result.

    In order to be able to gather data when running experimentations, metrics are scraped from the running processes by an instance of \gls{prometheus} running in each \gls{kubernetes} cluster.
    The data is then queried and aggregated in \gls{grafana}, which only runs in the \gls{minikube} cluster.
    Each deployment is registered in \gls{prometheus} via the \gls{pushgateway} running in the \gls{minikube} cluster.
    The \glsdisp{pushgateway}{Pushgateway} enables short running processes to report data, as \gls{prometheus} works by scraping data on a configured interval (Fig.~\ref{fig:impl_instr}).
