7 What is Cloud? : it depends who you ask... A user experience and a business model Cloud computing is an emerging style of IT delivery in which applications, data, and IT resources are rapidly provisioned and provided as standardized offerings to users over the web in a flexible pricing model. An infrastructure management and services delivery methodology Cloud computing is a way of managing large numbers of highly virtualized resources such that, from a management perspective, they resemble a single large resource. This can then be used to deliver services with elastic scaling and flexible pricing. 7

8 Varying opinions on its definition, but some common attributes are emerging IT Customers: IT Analysts: Common Attributes of Clouds Rapid provisioning Elastic scaling Standardized Offerings Advanced virtualization Flexible pricing Press: Financial Analysts: 8

9 Cloud services can be found in four service layers Internet / Intranet Business Process-as-a-Service Cloud Ecosystem Consulting Services Application/Software-as-a-Service Platform-as-a-Service Infrastructure-as-a-Service TSAM 9

14 In order to be able to use public / hybrid clouds, an organization must meet a number of criteria. In order to be able to use public / hybrid clouds an organization must at least have the following in place: Technological: o IT Standardization fully worked out o Well developed Systems Management Infrastructure o Implemented integration infrastructure o Proper security infrastructure o Virtualized infrastructure o Implement automated provisioning Organizational: o Well organized Service management (including ITIL processes) o Implementation of an IT usage based cost accounting model 14
