- 2. ABSTRACT •Internet Based Computing -SharedResources -Software -Information •Perfect System •Uses Advanced Business Model •Introduces the background, serv deployment models and se
- 3. INTRODUCTION How does CloudComputing work? •Metaphor for the Internet •Dynamically scalable shared resources accessed over a network •Subscription based Service •Examples: Google, Amazon,
- 4. Characteristics •On Demand SelfService •Broad Network Access •Resource Pooling •Cost •Location Independence •Maintenance •Virtualization •Reliabilty
- 5. Benefits •Cost Effective •Almost UnlimitedStorage •Backup and Recovery •Automatic Software Integration •Easy Access to Information •Quick Deployment
- 6. ARCHITECTURE •Multiple Cloud Components •Clients,Data Centre, Distributed Servers •Front End and Back End •Three Network Entities -User -CSP -TPA

- 8. •SaaS(Software as aService) •PaaS(Platform as a Service) •IaaS(Infrastructure as a Service) SERVICE MODELS
- 9. SaaS(Software as aService) •Application hosted as Service •Network Based Access •Customer free of worries •Provider does all Updates •Example: Gmail, salesforce.com
- 10. PaaS(Platform as aService) •Application delivery model •Supplies Resources •Application design, development environment, testing •Application Developers, testers •Lack of Portability
- 11. IaaS(Infrastructure as a Service) •ProvidesResources •Server space, Storage space, CPU cycles •Scaled up and down based on need •Charged by resources consumed

- 13. •Public Cloud •Private Cloud •HybridCloud •Community Cloud DEPLOYMENT MODELS
- 14. Public Cloud •Provide DiskSpace and Computing Power •Customer has no visibility about the infrastructure •Shared among organizations •Example: Amazon
- 15. Private Cloud •Solely forsingle organizations •Not shared •Managed by an organization or third party •Expensive and Secure •Example: Microsoft Private
- 16. Hybrid Cloud •Composition ofat least two Clouds •Private, Public or Community •Benefits of Multiple Deployment Models •Critical, secure applications in Private
- 17. Community Cloud •Shared between organizationsin the same community •Similar Cloud requirements •All Government Agencies in a City •Example: G-Cloud
- 18. SECURITY ISSUES Security Threats: InsecureAPI -Customers use API to access the Cloud -Must be highly secure Remedy: -Analyze the Security Model -Ensure strong Authentication
- 19. •Data Loss/Leakage -Unauthorized Access,Deletion -Top concerns for business Remedy: -Strong API Access Control -Encrypt and Protect Integrity of Data -Implement strong key generation, storage
- 20. •Network Sniffing -Data monitoredin a network -Attacker hacking passwords Remedy: -Encryption methods
- 21. Security Issues •Data Protection -Dataremains private -SSO technology, Encryption •Physical and Personnel Security -Security of Physical Machines -Customer data not only restric but also documented
- 22. •Availability -Data available wheneveruser needs it •Application Data -Applications are secure •Privacy -All critical data masked -Only authorized users have access
- 23. •Infinite Computing Capability •Providesservice on demand •Pay per use basis •Offers many benefits •It is vulnerable to security threats be lessened by taking some measu CONCLUSION
