  \frametitle{VM Platform vs. Cloud Platform}
  VM Platform:
  \begin{itemize}
  \item Managed by IT
    \begin{itemize}
    \item VMs
    \item ISOs/images
    \item Rudimentary networking
    \item Use pre-allocated storage
    \end{itemize}
  \end{itemize}
  Cloud:
  \begin{itemize}
  \item Managed by end users
    \begin{itemize}
    \item VMs
    \item images
    \item Advanced networking
    \item Advanced storage
    \item Object storage
    \item SSH keypair management
    \item APIs
    \item Orchestration
    \item Dashboard
    \end{itemize}
  \end{itemize}
\end{frame}

  \frametitle{Proprietary Public Cloud Platforms}
  \begin{itemize}
  \item Microsoft Azure
  \item Rackspace
  \item Amazon Web Services
  \item Google Cloud
  \end{itemize}
\end{frame}

\begin{frame}
  \frametitle{Private Cloud Platforms}
  \begin{itemize}
  \item Microsoft Azure (\$\$\$)
  \item OpenStack (sweat)
  \end{itemize}

  \frametitle{Evolution of the Cloud}
  \begin{enumerate}
  \item Baremetal servers in datacenters
    \begin{itemize}
    \item Costly
    \item 4-8 weeks from request to delivery
    \end{itemize}
  \item Non-cloud virtualization controlled by IT
    \begin{itemize}
    \item Cheaper
    \item Shorter time to delivery, but still moves at the speed of IT
    \end{itemize}
  \item Users abandoning IT in favor of public cloud providers
    \begin{itemize}
    \item More expensive than non-cloud virtualization, but cheaper
      than baremetal
    \item Instant push-button delivery
    \item Source of great conflict between users and IT
    \end{itemize}
  \item Private cloud platforms in the enterprise
    \begin{itemize}
    \item More expensive than non-cloud virtualization, but cheaper
      than public cloud
    \item Instant push-button delivery
    \item No more conflict between users and IT
    \end{itemize}
  \end{enumerate}
