Confidential▲Cloud computing provides resources on demand The definition of Cloud Computing “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” The National Institute of Standards and Technology Flexible allocation of logically Virtualisation partitioned resources at three service layers Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS)
