  • Essential Characteristics
    1. On-demand self-service
    A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider.
    2. Broad network access
    Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
    3.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. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines.
    4. Rapid elasticity
    Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
    5. Measured Service
    Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

    3. 3. Cloud A model for enabling 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.
    4. 4. Mobile Devices with Cloud Services; The limited processing and memory capabilities of mobile devices have always required some use of the "cloud" for delivery of mobile applications and services. However, the challenges inherent in application development as well as the desire to enhance applications with location, presence, and other value- added services are driving greater use of the cloud for creating advanced mobile applications.(ABIresearch) Mobile Cloud Computing FunctionalFunctional Processing Power Processing Power DataData UIUI GPS, Gyroscope, ...
