Defining Cloud Computing Two broad categories

Cloud applications

– Often called Software as a Service (SaaS)

Cloud platforms

– The focus of this presentation

Cloud Platform

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

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

– The technology can be much like public clouds, but the economics are different

Categorizing 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
