4. Cloud Computing provides variety of computing resources from servers and storage to applications such as , web-hosting, ERP & CRM packages etc. all are delivered over the Internet.
Cloud delivers hosting environment that is immediate, flexible, scalable, secure, and available – while saving the organizations money, time and resources.

5. Cloud Computing Delivery Models

6. Traditional Costs Continue to Grow
High CapEx
Low facility asset utilization (55%)
High Depreciation (42-50%)
Power/Cooling costs > Server Costs
Not “Green”
30% hardware obsolescence

7. Migrating to cloud computing
Colo
Managed
Colocation – 1st step to outsourcing
Managed Hosting – dedicated servers managed by 3rd party takes pain away
Cloud Hosting – Lower cost, easier, lower risk, more reliable

8. Cloud Computing Applications

9. 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

10. 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

11. Cloud “Infrastructure”
Provide “Compute” and “Storage” clouds
Virtualization layers (hardware/software)
Examples: Amazon EC2, GoGrid, Amazon S3, Nirvanix, Linode
Advantages: Full control of environments and infrastructure
Disadvantages: premium price point, limited competition

12. Cloud “Extenders” (Wild Card)
Provides extension to Cloud Infrastructure and Platforms with basic functionality
Examples: Amazon SimpleDB, Amazon SQS, Google BigTable
Advantages: Extends functionality of Compute & Storage Clouds to integrate with legacy system or other clouds
Disadvantages: Sometimes requires use of specific Platforms or Infrastructure

13. Cloud “Aggregators” (Wild Card)
Sits on top of various Cloud Infrastructures for management
Examples: RightScale, Appistry
Advantages: Provides more options for Cloud environments
Disadvantages: Dependent on Cloud Providers

14. Top 10 Cloud Computing Adopters
Messaging & team collaboration applications
Cross enterprise integration projects
Infrastructure consolidation & virtualization
Web content delivery services
Data analytics and computation
Mobility applications for the enterprise
Customer Relationship Management Packages
Enterprise Resource Management Packages
Experimental deployments and test-beds etc.
Backup and archival storage etc. 14

15. Advantages of Cloud Computing:
It can lower initial costs for start-up companies and for traditional companies which own IT resources.
It provides IT resources immediately and enables scalability according to needs of user or customer.
Usage of cloud computing services can foster innovation because there are no huge upfront costs for test and development environments.
