Recap & Conclusion

Challenges

Cloud Models
Virtualized
Software as a Service (SaaS)
Subscribe to web editions of traditional packaged applications
Platform as a Service (PaaS)
Write applications specifically to run on a Cloud platform
Web Based Services
Internet Web Sites, finished web experiences
Application Components as a Service
Building block services and features
Infrastructure as a Service (IaaS)
Host existing applications as Virtualized Machines in the Cloud

Cloud Considerations
Pay for access – not ownership
Improve time-to-market
Staff and plan for typical usage
Scale to the cloud at peak times
Focus essential IT resources on business solutions
Gain massive scalability
Increase business agility

So, here are the various options
Application runs
on-premises
Buy my own hardware, and manage my own data center
Application runs
on-premises
Bring my own machines, connectivity, software, etc.
Complete control and responsibility
Upfront capital costs for the infrastructure
Application runs at a hoster
Pay someone to host my application using hardware that I specify
Application runs at a hoster
Rent machines, connectivity, software
Less control, but fewer responsibilities
Lower capital costs, but pay for fixed capacity, even if idle
Application runs using cloud platform
Pay someone for a pool of computing resources that can be applied to a set of applications
Application runs using Public cloud platform
Shared,
multi-tenant environment
Offers pool of computing resources, abstracted from infrastructure
Pay as you go

What Should The Cloud OS Provide?
The same facilities that a desktop OS provides, but on a set of connected servers:
Abstract execution environment
Shared file system
Resource allocation
Programming environments
And more: Utility computing
24/7 operation
Pay for what you use
Simpler, transparent administration

Windows Azure, Bit By Bit
Developer platform, designed top down
Cloud infrastructure, built bottom up
