2. Defining Cloud Computing
Two broad categories

Application
Cloud Platform
Users Developers
 Cloud applications
– Sometimes called Software as a Service (SaaS)
 Cloud platforms
– The focus of this talk

3. Defining Cloud Computing
Examples
 Cloud applications:
– Salesforce.com CRM
– Google Apps
– Microsoft Exchange Online
– Your favorite Web site (?)
 Cloud platforms:
– Amazon Web Services (AWS)
– Google AppEngine
– Microsoft Windows Azure platform
– Salesforce.com Force.com

4. What is a Cloud Platform?
Some defining characteristics
 It lets developers create and run apps, store
data, and more
 It provides self-service access to resources, e.g.,
via a browser
 It allows granular, on-demand allocation of
resources
 It charges only for the resources an application
uses

5. Public Clouds vs. Private Clouds
Typical definitions
 Public cloud: A cloud platform run by a service
provider, such as Microsoft, Amazon, or
Google, made available to many end-user
organizations
 Private cloud: A cloud platform run solely for a
single end-user organization, such as a bank or
retailer

6. Categorizing Public Cloud Platforms
The usual split
 Infrastructure as a Service (IaaS)
– Developers create virtual machines (VMs), to
which they have full access
– Provides total control, but also total responsibility
 Platform as a Service (PaaS)
– Developers provide an application, which the
platform runs
– Provides an easy-to-use execution environment,
but limits freedom
