What is cloud computing?
Very simply stated, cloud computing is the delivery of a service or a capability over the network. More specifically, cloud computing refers to IT resources and services that are abstracted from the underlying infrastructure and are provided "on demand" and "at scale" in a multitenant environment.
What are the benefits of cloud computing?
Cloud computing fundamentally changes the way IT services are delivered. Organizations can employ cloud computing to meet their IT requirements using a flexible, on demand, and rapidly scalable model that requires neither ownership on their part, nor provision of dedicated resources.
Are there security issues connected with cloud computing?
Traditional issues around data and resource access control, encryption, and incident detection are factors in cloud computing. The key take-away in cloud data center computing is that security should not be an afterthought or a building block; it should be pervasively implemented across all layers of architecture
