Was bedeutet Cloud?

Das International Software Architecture Qualification Board  (ISAQB) definiert den Begriff „Cloud“ wie folgt:

Unter Cloud versteht man

“Cloud computing is a model for enabling ubiquitous, convenient, on-demand networ
access to a shared pool of configurable computing resources (e.g., networks, servers
storage, applications, and services) that can be rapidly provisioned and release
with minimal management effort or service provider interaction.”

Definition quoted from NIST</a
(National Institute of Standards and Technology).

The NIST definition contains the following five characteristics (quoted but abbreviate
from the aforementioned NIST source too):

<ul

  • On-demand self service: A consumer can unilaterally provision computing<br
    capabilities, such as server time and network storage,<br
    without requiring human interaction with each service provider. </li
  • Broad network access: Capabilities are available over the network an
    accessed through standard mechanisms that promote use by heterogeneou
    client platforms.</li
  • Resource pooling: The provider’s computing resources are pooled to serve<br
    multiple consumers using a multi-tenant model, with different physical and<br
    virtual resources dynamically assigned and reassigned according to consumer demand
    There is location independence in that the customer generally has no control o
    knowledge over the exact location of the provided resources but may be able t
    specify location at a higher level of abstraction (e.g., country, state, or datacenter).<br
    Examples of resources include storage, processing, memory, and network bandwidth.</li
  • Rapid elasticity: Capabilities can be elastically provisioned and released
    in some cases automatically, to scale rapidly commensurate with demand
    To the consumer, the capabilities available for provisioning often appea
    to be unlimited and can be appropriated in any quantity at any time.</li
  • Measured service: Cloud systems automatically control and optimize resourc
    use by leveraging a metering capability at some level of abstractio
    appropriate to the type of service (e.g., storage, processing, bandwidth
    and active user accounts). Resource usage can be monitored, controlled, an
    reported, providing transparency for both the provider and consumer of th
    utilized service.</li
