Deployment models

■ Public cloud: open for public use■ Private cloud: operated entirely

for a single organization■ Hybrid cloud: a composition of

two or more clouds

Service models

■ Software as a service (SaaS)

■ Platform as a service (PaaS)

■ Infrastructure as a service (IaaS)

Software as a service (SaaS)

■ On-demand software■ Vendors provide complete

management■ Priced on a pay-per-use basis or

using a subscription fee■ Example: Google Apps,

Salesforce, Cisco WebEx, etc

Platform as a service (PaaS)

■ Development platform■ Vendors manage IT, OS, app

server, DB and web server■ Auto scaling resources■ Example: Google App Engine,

Microsoft Azure, etc

Infrastructure as a service (IaaS)

■ Remote datacenter infrastructures (compute, storage, networking)

■ Vendors manage physical resources

■ Example: Google Cloud Engine, Amazon AWS, etc

Cloud main benefits

■ Cost savings■ Self-service provisioning■ Flexibility■ Elasticity■ Technology innovation

Cloud main challenges

■ Security■ Control■ Compatibility with existing

applications■ Privacy■ Performance

Cloud computing numbers

According to IDC’s five-year forecast, cloud infrastructure IT spending is set to grow at a compound annual growth rate (CAGR) of 15.1% and will hit
