Moreover, \code{Schema Registry} is compatible with versatile data interchange formats, such as \code{ProtoBuf}~\cite{Wikipedia:article/ProtoBuf}. +\code{Redis}, is a key value store that provides efficient store and retrieval operations~\cite{Wikipedia:article/Redis}. +In particular, \code{Redis} is capable of storing \emph{streams} -- append only logs which allow for fast and quick query of large volumes of data. +\code{Redis} is the industry leader in key value caching. +The only alternative to \code{Redis} is \code{memcached}~\cite{Wikipedia:article/Memcached}, which does not provide the capability to integrate with \code{Kafka}. + +\code{PostgreSQL} is a database management system, necessary to store large volumes of out-of-band data coming from the physical datacenter. +The \code{PostgreSQL} server provides a simple and straightforward interface to query the data via \code{psql}. +Importantly, to adhere to the single responsibility principle, \code{PostgreSQL} does not provide any \gls{ui}. +Additionally, there exist many integrations between \code{PostgreSQL} and other software, including \code{Kafka}. +The many alternatives to \code{PostgreSQL} are listed in~\cite{Wikipedia:article/Postgresql}. +An alternative used in previous work is \code{InfluxDB}~\cite{DBLP:conf/wosp/SumanCNTMI24}. + +Lastly, to enable predictive analytics we use a state-of-the-art discrete-event simulator, \code{OpenDC}~\cite{GitHub:software/OpenDC}. +\code{OpenDC} is a leading software package capable of modeling complex datacenter phenomena and workloads (\eg failures,
