Cloud Computing - Beyond the Blue Horizon

  1. 1. Cloud Computing – Beyond the Blue Horizon James Dowell – Enterprise Sales Engineer
  2. 2. What is the cloud?• Cloud computing provides computation, software, data access, and storageservices that do not require end-user knowledge of the physical location andconfiguration of the system that delivers the services. Parallels to this concept canbe drawn with the electricity grid, wherein end-users consume power withoutneeding to understand the component devices or infrastructure required to providethe service.• The concept of cloud computing fills a perpetual need of IT: a way to increasecapacity or add capabilities on the fly without investing in new infrastructure,training new personnel, or licensing new software. Cloud computing encompassesany subscription-based or pay-per-use service that, in real time over the Internet,extends ITs existing capabilities.* Ref. Wikipedia
  3. 3. Hosted vs The Cloud• The plain fact is that cloud is normally cheaper than hosted, because cloudapplications or services have been engineered to share resources efficiently,something that hosted applications or services can’t do, because they’ve had tobe rewritten from the ground up.• Hosted services can also be as simple as internet access and a power supply.While some others also provide you a platform, the general maintenance andsecurity is in your hands.
  4. 4. The cloud isn’t secure!?• One of the future predictions for cloud computing is securePCI compliant payment systems!• Application, network & data security is complex, expensiveand requires skilled people and resources.• Most organizations utilize cloud based solutions to leveragethese security features.• Also the cost of maintaining these systems with skilledengineers is very high.

  10. 10. History of backupMedia and methods have evolved, cloud backup is most recent.
  11. 11. Cloud storage Large business-grade deployment with high quality of service creates good economies of scale.Thousands Petabytes Backup Window Economiesof customers of storage Decreased of scale
  12. 12. Where else does cloud work ?• When the geographic location is important.
