Cloud computing is a model for facilitating expedient, on-demand network access to a shared pool of computing resources (e.g., networks, storage, servers, services and applications) that can be rapidly provisioned and released with minimal management effort or service provider communication. This cloud model endorses availability and is composed of five essential characteristics (on-demand self-service, resource pooling, broad network access, measured service and rapid elasticity). Also research communities such as AMO (Atomic, Molecular and Optical) physics research, biology and neuroscience are investigating the relevance of clouds, with their strengths and weaknesses in scientific environments.
