" Cloud comes from the early days of Internet where we drew the network as a cloud... we didn't care where the message went- the cloud hid it from us ", Kevin Marks, Google
to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents.
Because like cloud, internet is hard to measure, elastic, flexible
Characteristics of Cloud Computing First, the SPI Model Cloud S oftware as a Service ( S aaS) Cloud P latform as a Service ( P aaS) Cloud I nfrastructure as a Service ( I aaS)
Characteristics of Cloud Computing Network based or Internet based
Characteristics of Cloud Computing On-demand capabilities : A business will secure cloud- hosting services through a cloud host provider which could be your usual software vendor. You have access to your services and you have the power to change cloud services through an online control panel or directly with the provider. You can add or delete users and change storage networks and software as needed. Typically, you are billed with a monthly subscription or a pay-for-what-you-use scenario. Terms of subscriptions and payments will vary with each software provider.
Characteristics of Cloud Computing Rapid elasticity : If anything, the cloud is flexible and scalable to suit your immediate business needs. You can quickly and easily add or remove users, software features, and other resources.
Measured service. Cloud systems automatically control and optimize resource usage by leveraging a metering capability at some level of abstraction appropriate to the type of service. Resource usage can be monitored, controlled, and reported - providing transparency for both the provider and consumer of the service. Characteristics of Cloud Computing
Resource pooling. The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. Characteristics of Cloud Computing
