Community Clouds
The document discusses cloud computing models, focusing on community clouds and their relevance to higher education. It outlines various service models (IaaS, PaaS, SaaS) and deployment models (public, private, community, hybrid) while emphasizing the advantages of community clouds for academic institutions. Additionally, it suggests strategic approaches for adopting cloud services, addressing potential risks and challenges, and encourages participation in existing communities for better collaboration and resource sharing.
