¿Cómo poner título en dedicatoria?

Question

Quiero poner el título más grande, sin perder la alineación del párrafo de la dedicatoria.

\documentclass[a4paper,12pt]{article}
\usepackage[paper=a4paper,left=30mm,right=20mm,top=25mm,bottom=30mm]{geometry}

\newenvironment{dedication}
  {\clearpage           % we want a new page
   \thispagestyle{empty}% no header and footer
   \vspace*{\stretch{1}}% some space at the top 
   \raggedleft
   \leftskip=5cm
   \parindent=10pt
   \itshape             % the text is in italics

  }
  {\par % end the paragraph
   \vspace{\stretch{3}} % space at bottom is three times that at the top
   \clearpage           % finish off the page
  }

\begin{document}
\begin{dedication}
Dedicated to google and wikipedia by models (SaaS, PaaS, and IaaS), the CP provides the storage and processing facilities
needed to support that service model, together with a cloud interface for cloud
service consumers. For SaaS, the CP deploy
\end{dedication}
\end{document}

Puedes usaralcance(usando {... }o \begingroup... \endgroup) para limitar el efecto de \raggedleft, o puede usar \justifyingdesderagged2epara restaurar el aspecto justificado de un párrafo después de algo como \raggedlefto \centering:

\documentclass{article}

\usepackage{ragged2e}

\newenvironment{dedication}
  {\clearpage           % we want a new page
   \thispagestyle{empty}% no header and footer
   \vspace*{\stretch{1}}% some space at the top 
   \raggedleft          % Flush with right margin
   \section*{Dedication}% Formatting of dedication title (as section*)
   \itshape             % the text is in italics
   \justifying          % layout of dedication paragraph

  }
  {\par                 % end the paragraph
   \vspace{\stretch{3}} % space at bottom is three times that at the top
   \clearpage           % finish off the page
  }

\begin{document}

\begin{dedication}
  Dedicated to google and wikipedia by models (SaaS, PaaS, and IaaS), the CP provides the storage and processing facilities
  needed to support that service model, together with a cloud interface for cloud
  service consumers. For SaaS, the CP deploy.
\end{dedication}
