Cloud Applications

SaaS resides here

Most common Cloud / Many providers of

different services

Examples: SalesForce, Gmail, Yahoo! Mail,Quicken Online

Advantages: Free, Easy, Consumer

Adoption Disadvantages: Limited functionality, no

control or access to underlying technology

Cloud Platforms

Containers, Closed environments

Examples: Google App Engine, Heroku,Mosso, Engine Yard, Joyent or Force.com

(SalesForce Dev Platform) Advantages: Good for developers, more

control than Application Clouds, tightly

configured Disadvantages: Restricted to what is

available, other dependencies

12

Cloud Infrastructure

Provide Compute and Storage clouds

Virtualization layers (hardware/software)

Examples: Amazon EC2, GoGrid, AmazonS3, Nirvanix, Linode

Advantages: Full control of environmentsand infrastructure

Disadvantages: premium price point, limitedcompetition

Single-Tenant vs. Multi-Tenant

Architecture

17

Single tenancy gives each customer adedicated software stack and each layer in

each stack still requires configuration,

monitoring, upgrades, security updates,

patches, tuning and disaster recovery.

On a multi-tenant platform, all applicationsrun in a single logical environment: faster,

more secure, more available, automatically

upgraded and maintained. Any improvement

appears to all customers at once.
