  1. 1. CLOUD COMPUTING Presented By Abir Jashu M.S.I.T.
  2. 2. What is Cloud Computing 2 Shared pool of configurable computing resources On-demand network access Provisioned by the Service Provider
  3. 3. Cloud Computing Technologies o Technology context: multi-core, virtualization, 64-bit processors, parallel computing models, big-data storages… o Cloud models: IaaS (Amazon AWS), PaaS (Microsoft Azure), SaaS (Google App Engine)
  4. 4. Cloud Technologies 64-bit processor Multi-core architectures Virtualization: bare metal, hypervisor. … VM0 VM1 VMn Web-services, SOA, WS standards Services interface Storage Models: S3, BigTable, BlobStore, ... Bandwidth WS 6/23/2010Wipro Chennai 2011 4 Cloud applications: data- intensive, compute- intensive, storage- ntensive
  5. 5. Cloud Architecture 5
  6. 6. Types of cloud computing 6 For one Organization On a private N/W. Highly Secure Owned by Cloud server provider Combination Of private & Public
  7. 7. Type of Services Infrastructure As a service Platform as a service Software as a service
  8. 8. Cloud computing takes virtualization to the next step  You don’t have to own the hardware  You “rent” it as needed from a cloud  There are public clouds  e.g. Amazon EC2, and now many others (Microsoft, IBM, Sun, and others ...)  A company can create a private one  With more control over security, etc. 8
  9. 9. How cloud computing work
  10. 10. Virtual Machines  VM technology allows multiple virtual machines to run on a single physical machine. 10 Hardware Virtual Machine Monitor (VMM) / Hypervisor Guest OS (Linux) Guest OS (NetBSD) Guest OS (Windows) VM VM VM AppApp AppAppApp Xen VMWare UML Denali etc. Performance: Para-virtualization (e.g. Xen) is very close to raw physical performance!
  11. 11. The Virtual Private Cloud Private Cloud (Internal) Private Cloud (External) Non-Cloud Local Applications Community Cloud (External) Public Cloud (External) Public Clouds (External) Public Clouds (External) Partners Inter-Cloud Access Communications Circuit (dedicated, Internet, etc.) Public Clouds (External) External Hosted Applications Mobile devices can participate as peer nodes within this concept
  12. 12. Another possible privacy and security solution is to use a technique called steganography :  Multimedia content like images and videos have significant redundancy. This makes it possible to hide data in multimedia using steganography.  Steganographic techniques can be used to transform the data before storage so that operations can still be performed on the data.
  13. 13. Cloud Providers
  14. 14. Suppose you are Forbes.com  You offer on-line real time stock market data  Why you pay for your used time(5PM-9AM) 14 9 AM - 5 PM, M-F ALL OTHER TIMES Rate of Server Accesses EXAMPLE Time
  15. 15. Forbes' Solution  Host the web site in Amazon's EC2 Elastic Compute Cloud  Provision new servers every day, and deprovision them every night  Pay just $0.10* per server per hour  * more for higher capacity servers  Let Amazon worry about the hardware!
  16. 16. Advantages of Cloud Computing  Lower computer costs  Improved performance  Reduced software costs  Instant software updates  Improved document format compatibility  Unlimited storage capacity 16
  17. 17. Advantages of Cloud Computing  Increased data reliability  Universal document access  Latest version availability  Easier group collaboration  Device independence 17
  18. 18. Problems  Requires a constant Internet connection.  Does not work well with low-speed connections  Features might be limited  Even with a fast connection can be slow  Stored data might not be secure  Stored data can be lost  Without 3G connection Cloud computing not effective 18
  19. 19. CONCLUSION AND FUTUREWORK  Cloud computing can potentially save energy for users.  The services should consider the energy overhead for privacy, security, reliability, and data communication before offloading.  Any where any place we can access information  According to a recent study by ABI Research, a New York-based firm, more than 240 million business will use cloud services through mobile devices by 2015.
