+	\begin{tcolorbox}[title=Definition]
+		A DCDT mirrors the structure, context and behaviour of a datacenter~\cite{DBLP:journals/computer/AthavaleBBMMPS24}. The prerequisite to any digital twin is good monitoring and sensing capabilities in the physical entity.
+		Datacenters meet this requirement easily because they already connect hundreds of monitoring sensors. 	\end{tcolorbox}

+	\textbf{Figure E.3:} Due to insufficient technological foundations,
+	little work is available on DTs between 2003 and 2018, and it is only with the rapid growth
+	of cloud computing, Internet-of-Things and Big Data analytics that DTs have reemerged~\cite{DBLP:conf/cirp/TAO2018169}.
+	That is why nobody used digital twins to mirror datacenters earlier.

+		Preventing failure-caused outages in advance
+		can reduce huge operational costs, as over 20\% of all reported outages amount to more than 1 million
+		US\$~\cite{DBLP:report/AnnualOutageAnalysis2025}.
+		Only a constant bi-directional interaction (digital twin $\iff$ physical entity) can achieve this.
