Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet,
a collection/group of integrated and networked hardware, software and Internet infrastructure.
provides hardware, software and networking services to clients.
These platforms (networked hardware) hide the complexity to provide a very simple service.

Transcript

  • 1. Cloud ComputingFares JemniAli Ben Messaoud
  • 2. Plan• Introduction• What is Cloud Computing ?• Cloud Computing Approaches• Key Technology: Virtualization• Conclusion
  • 3. Introduction• Cloud Computing is a new and exciting trend which many of us, even in the information technology field are, let’s say, a “little cloudy about”.• What is cloud computing?• Are there different levels or types of cloud computing?• Who exactly are these cloud computing providers?
  • 4. What is Cloud Computing?• Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet, • a collection/group of integrated and networked hardware, software and Internet infrastructure • provides hardware, software and networking services to clients• These platforms (networked hardware) hide the complexity to provide a very simple service
  • 5. What is Cloud Computing?• Anything outside of your system’s firewall and includes a pay-per-use or subscription service that extends your agencies information technology through the internet as the primary access point.
  • 6. Basic Cloud Characteristics• “no-need-to-know” • details of infrastructure, applications interface with the infrastructure via the APIs.• “flexibility and elasticity” • scale up and down allocated resource• “pay as much as used and needed”• “always on!, anywhere and any place”
  • 7. 3 Approaches to Cloud Computing• Software as a service (SaaS) : • access to software and its functions remotely through internet browsers.• Platform as a service (PaaS) : • computing platform is being delivered as a service, eg. purchase and manage hardware remotely.• Infrastructure as a service (IaaS) : • defined as computer infrastructure, such as virtualization, being delivered as a service. • billed on usage and how much of the resource is used in data centers for example.
  • 8. XaaS
  • 9. Key Technology: Virtualization• The ability to run multiple version of something, such as a hardware platform, operating system, a storage device or network resources on a single physical system and share the underlying hardware resources.• cloud computing is famous for scalability because of virtualization.• Without virtualization, cloud computing as we know it would not exist or would be in a different form.
  • 10. Virtualize for Efficiency, HigherAvailability, and Lower Costs• Run multiple operating systems and applications on a single computer• Consolidate hardware to get vastly higher productivity from fewer servers• Save 50% or more on overall IT costs• Speed and simplify IT management, maintenance, and the deployment of new applications
  • 11. Virtualization How it Works?
  • 12. Virtualization+Cloud
  • 13. Conclusion• Cloud computing is the future. • Cost • Performance • Data and Security • Support • Service Level Agreements
