Cloud computing conceptsOn demand, internet-based computing
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
$53.1bn by 2019.
By this time, it will also account for nearly half of all
enterprise IT spend
