\begin{mynote}
	Our contribution in this chapter is three-fold:
	\vspace{-0.2cm}
	\begin{enumerate}[label=\emph{C\textsubscript{\arabic*}}, itemsep=0.2pt]
		\item We analyze the requirements for \mysystem (\Cref{ss:requirements_analysis}).
		\item We propose a conceptual design for \mysystem's architecture (\Cref{ss:design_of_mysystem})
		\item We describe how \mysystem enables predictive analytics through digital twinning (\Cref{ss:design_discussion})
	\end{enumerate}
\end{mynote}
\section{Requirements Analysis}\label{ss:requirements_analysis}
In this section we determine the requirements that should be fulfilled by \mysystem.
We present here the stakeholders identified by our literature survey (see \Cref{sss:digital_twins_for_datacenters}) and the relevant use-cases.
Afterwards, we list the functional and non-functional requirements for \mysystem.
