This document discusses cloud computing, including its key characteristics, services, deployment models, advantages and disadvantages. Cloud computing refers to utilizing online servers rather than local systems for file storage, applications and other services. The main types of cloud services discussed are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The document also covers public, private, community and hybrid cloud deployment models and some advantages of cloud computing like cost savings and scalability and disadvantages like internet dependency.
