  3. 3. Example of Cloud Computing Google Apps: provides the service of business applications such as Gmail, Google Talk, Google Calendar and Google Docs, etc.  Amazon Web Services: The services offered are the Amazon EC2 , Amazon S3, Simple DB , Amazon SQS .  Azure: Microsoft provides operating system services, hosting, systems development.

  8. 8. Google App Engine 10
  9. 9. Software as a service (SaaS) This is the most common form of cloud computing which we see in action. It is a complete software offering on the cloud. They are accessed by the customers on pay per use basis. Example:Gmail , Hotmail etc
  10. 10. Platform as a service (PaaS) The consumer creates the software using tools and libraries from the provider. The consumer also controls software deployment and configuration settings. The provider provides the networks, servers and storage . Example:Wavemaker,Longjump etc
  11. 11. Infrastructure as a service (IaaS) Hardware related services are provided using the principles of Cloud Computing. These include disk storage and virtual servers. Amazon EC2, Amazon S3, Rackspace Cloud Servers are some of the leading vendors.
  12. 12. Cloud Computing classified basis of location • • • • Public Cloud Private Cloud Hybrid Cloud Community Cloud
  13. 13. Public Cloud Computing infrastructure is hosted at the vendor’s premises. The customer has no visibility over the location of the cloud computing infrastructure. The computing infrastructure is shared between organizations.
  14. 14. Private Cloud Computing architecture is dedicated to the customer and is not shared with other organisations.Private clouds may be externally hosted ones as well as in premise hosted clouds.
  15. 15. Hybrid Cloud Organisations host some critical, secure applications in private clouds. The not so critical applications are hosted in the public cloud. The combination is known as Hybrid Cloud.
  16. 16. Community Cloud The cloud infrastructure is shared between the organizations of the same community.
  17. 17. 1. Public Cloud - A public cloud can be accessed by any subscriber with an internet connection and access to the cloud space. 2. Private Cloud - A private cloud is established for a specific group or organization and limits access to just that group. 3. Community Cloud - A community cloud is shared among two or more organizations that have similar cloud requirements. 4. Hybrid Cloud - A hybrid cloud is essentially a combination of at least two clouds, where the clouds included are a mixture of public, private, or community
  18. 18. Benefits - Reduced hardware software cost -Reduced maintenance cost -High performance -High reliability -High scalable on demand -Multi tenancy -Batter security - Virtualization
  19. 19. Disadvantages Security Issues Terms of Service Privacy Policies
  20. 20. Conclusion • Clouds  Provide internet based services  Available on demand  And fully managed by the provider  There is no one “Cloud”. There are many models and architectures • Clouds let you  Avoid capital expenses on hardware, software, and service  Share infrastructure and costs  Lower management overhead  Access a large range of apps
  21. 21. Conclusion Like everything else, cloud computing too has its pros and cons. While the technology can prove to be a great asset to your company, it could also cause harm if not understood and used properly
  22. 22. Green benefits of Cloud Computing Servers  Reduce the number of servers : 5 to 10 virtual servers to 1 physical server  Less space required  Reduced power  More energy efficient servers Workstations  Thin clients -> reduced power ,  Virtual workstations running on servers : 30 to 70 wks to 1 server IT Support  Workstations that are not used are switched off,  Maintenance performed real time. Environmental  Lower carbon emissions : less power needed  Recycle old equipment
  23. 23. Preparing for the Future Sampling of IT skills likely to be in demand in the future – Functional application development and support • I.e. Oracle, SAP, SQL, linking hardware to software – Leveraging data to make strategic business decisions • I.e. Business Intelligence : Applying sales forecasts to inventory and manufacturing decisions – Mobile apps • Android, iPhone, Windows Mobile – WiFi engineers • USF to include broadband communications (LTE replaces GSM/CDMA) – Optical engineers • Optical offers the highest bandwidth today (PON, CWDM, DWDM) – Virtualization Specialists • Economies of scale require virtualization (server, storage, client…) – – – – – IP Engineers Network Security Specialists Web developers Social Media developers Business Intelligence application development and support
