This document discusses libraries moving services to the cloud. It begins by defining cloud computing and the different types of cloud models including infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Examples are given of how libraries currently use each cloud model. Considerations for libraries transitioning to the cloud include budget, personnel needs, bandwidth requirements, and service level agreements. The presentation raises questions about reliability, control, and the risks of vendor lock-in.
