  • 1. Cloud Computing & Cloud Architecture The Advantages & Disadvantages It Presents CC PublicDomainPictures
  • 2. Cloud Computing Continuously growing! Services available without need of powerful PCs Devices like smartphones can access easily CC GoodNCrazy
  • 3. How & Why? Companies with huge server collections connected to the Internet More widely available due to broadband and cheaper storage costs CC Jamison_Judd
  • 4. Change of Focus “Computer architectures should shift the focus of Moore’s Law from increasing clock speed per chip to increasing the number of processor cores and threads per chip.” Sameli CC Ioan
  • 5. Coming Changes From Hard Disk …To Solid State Drives Drives…CC Simon Wüllhorst
  • 6. Data Management Shift from home desktops towards next-gen data centres Database management systems needed to control cloud capabilities CC IntelFreePress
  • 7. “Cloud computing provides environments to enableresource sharing in terms of infrastructure, middlewareand application development platforms.” CC theaucitron
  • 8. Resource Types Typically 4 different types: ◦ Infrastructure resources ◦ Software resources ◦ Application resources ◦ Business processes Shareable resources, support “open cloud” ethos CC Richard Masoner/ Cyclelicious
  • 9. Infrastructure Resources Includes “computing power, storage and machine provisioning” CC Kinologik CC Google
  • 10. Software Resources Middleware like cloud-based operation systems, applications servers and databases Eg, Red Hat or Traffic Server CC Red Hat CC Apache Traffic
  • 11. Application Resources Companies moving applications off home computers onto the Internet Delivered through Software as a Service (SaaS) model CC Google Eg, Google Docs
  • 12. Business Processes Use their own internal applications to reduce third party dependency
  • 13. Security Ever present security threats! Needs to be to the same, if not to a greater degree than if cloud not used at all CC bclinesmith
  • 14. Data Storage Data has to be stored in a hard format somewhere Security needs to be provided for this lydia_shiningbrightly CC
  • 15. Data Access Hackers are potential threat Cloud providers need to control access to data CC gpuhackr
  • 16. Data Classification Data must be separated Data should be encrypted for security CC mcfarlandmo
  • 17. The Cloud as a Technology Streamline and minimize computer interaction “Cloud computing is a disruptive technology with profound implications, not only for Internet services, but also for the IT sector as a whole.”
  • 18. A “Killer App” Yet to be developed Various barriers in the way
  • 19. The Future… If it can be imagined, it can be perfected Huge potential in the coming years… backofthenapkin CC
