  3. 3. “A buyer centric view of technology where applications are available, through purchase, rental or even development, wherever and whenever.” What is cloud computing? Cloud Computing is …….. “An approach to consume technology in a pay-as-you-go model where consumers only pay for what they use.”
  4. 4. Service Types oSaas oPaas oIaas Layers
  5. 5. Software as a service(Saas):- Software deployed as a hosted service accessed over the internet Features:- •Open,Flexible •Easy to upgrade •Easy to deploy •Easy to use
  6. 6. Platform as a service:- Platform providing all the facilities necessary to the complete process of building and delivering web applications and service, all available over the Internet. Entirely virtualized platform that includes one or more servers,operating systems and specific applications Features:- •Database management system •Server Software •Support •Storage
  7. 7. Infrastructure-as-a-Service(Iaas):- Infrastructure as a service delivers basic storage and Compute capabilities as standardized services over the network. Server ,storage system,switche,router and other system are Pooled and made available to handel workloads the range from application components to high-performance computing Applications. Features:- • The service provider owns the equipment and is responsible for housing,running and maintaining it. • The client typically pays on a per-use basis.
  8. 8. Patterns For Cloud Computing:-
  9. 9. Public Cloud:- •A single or combination of SaaS,IaaS,PaaS offerings shall be shared between multiple companies to reduce costs and enable a dynamic resource usage following a pay-per-use pricing model. •Additional security mechanisms are implemented to isolate customers from each other.
  10. 10. Private Cloud:- •A single or combination of SaaS,IaaS,PaaS offerings shall be used internally of a company since privacy requirements or restrictions by law render the usage of public clouds impossible. •A private cloud is established in a dedicated data center by the company itself or by an external provider. The services offered by this cloud are only accessible by one company.
  11. 11. Hybrid Cloud:- •A single or combination of SaaS,IaaS,PaaS offerings shall be offered exclusively to companies with high privacy and security requirements while others shall be shared between multiple companies to reduce costs of the offerings and enable a dynamic resource usage following a pay-per-use pricing model. •A hybrid cloud integrates services of public and private clouds and establishes common management functionality.
  12. 12. Evolution & Market Drivers:-
  13. 13. As an end-consumer, believe it or not you’ve been using Cloud for long times •Keep up Friends •Share what’s new •Gmail •Drive •Online CRM •Buy Books online
  14. 14. Key Player’s in Market:- Ec2 Cloud (Elastic Compute) S3 storage (Simple storage service) Elastic app Infrastructure App Platform Websites Virtual Machine Data Management Websites App Platform
  15. 15. Private Cloud vendors (Data Centers):- ▫IBM ▫Vmware ▫Sun/Oracle ▫3Tera Hosting players Hundreds of them around the world Ex-Godady.com Hostgator.com
  16. 16. Global Perspective:- •A Market survey says the cloud market will reach 270 billion dollars in 2020 estimating that it will hit 143 billion dollars by 2013. •The top five rankings for markets with the most robust cloud policies went to Japan, Australia, Germany, the United States, and France. •Today there are 100 cloud companies ,in two years there will be 5000.
  17. 17. Smart Devices Cloud Connection • Broad band conectivity • Run Sophisticated apps • Rich media and social networking • Location services • Accessible by everyone from anywhere
  18. 18. Green IT Strategy via Cloud:- •In theory, a shared resource like Amazon or Google's public clouds can have higher utilization and thus greater power efficiency. •Cloud-based enterprise mobility ! It reduces the significance of device operating systems, providing easier multi-vendor support and enabling access to applications from mass-market handsets; it reduces the amount of data stored on the device
  19. 19. Pro’s & Con’s:- Pro’s •Cost reduction •It’s scalable •Easier collaboration •Increased Storage Capacity •Backup and Recovery •Cloud is environmentally friendly
  20. 20. Con’s •Availability •Data mobility and ownership •Technical Difficulties and Downtime •Increased Vulnerability
  21. 21. Conclusion:- •Despite its disadvantages and the fact that it is still in an infant age, cloud computing remains strong and has great potential for the future. Its user base grows constantly and more big players are attracted to it, offering better and more fine tuned services and solutions. •If you decide that your business should be in the cloud, be sure to take the time to layout your transition plan and determine how you will make progress.
