Cloud Computing

The word 'cloud' is a metaphor for the Internet. IT resources, software applications and services are provided via the World Wide Web. The user only needs a web-enabled device, to access all cloud services.  
An example of a cloud service is the provision of a WMS in the cloud, which simultaneously provides data storage and the necessarily computing power.

Dr. Chris Harding summarizes briefly the idea of cloud WMS in the book "Cloud Computing for Business":
„Cloud computing is 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. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.”
