3. NIST defines cloud computing as a set of characteristics, delivery
models, and deployment models
5 Characteristics
On-demand self-service
Ubiquitous network access 3 Delivery Models
Software as a Service (SaaS)
Resource pooling
Platform as a Service (PaaS) 4 Deployment Models
Rapid elasticity
Private Cloud
Infrastructure as a Service
Pay per use
(IaaS)
Community Cloud
Public Cloud
Hybrid Cloud
5. PaaS in the Real World
• Good
– Budget - It’s cheap.
– Power - It scales.
– Development – It’s
productive.
• Bad
– Limitations - Can only
use what’s there.
– Standards - Few exist.

• Bottom-up approach
• Simplicity with a higher degree of
control for the developer
10. Real World Advice
• Make sure to consider the target application.
– Static application requirements often lead to PaaS not being a
fit.
• Make sure to consider resources required.
– PaaS clouds limit use of resources, or they become too
expensive quickly.
• Make sure to consider data persistence.
– Data support varies greatly.
• Make sure not to get religious around the languages.
– “We’ll do it in any language as long as it’s Python.”
• Make sure to consider leveraging the outside world.
– Need to interact with other clouds, and on-premise systems.
• Make sure to consider staging and testing.
11. Best Practices
• Start with the data, and work up to the services and UI.
Not matter what the PaaS provider suggests.
• Create an initial POC, and make sure to validate the
complete stack.
• Define a staging and testing strategy before you begin
development.
• Consider SOA approaches in the design and deployment of
the PaaS-based application.
• Make sure to do load testing along with functional testing.
• Make sure to model performance.
• Don’t fall in love with a PaaS player. You may need to use
several.
