Cloud Computing & Cloud Architecture

  1. 1. Cloud Computing & Cloud Architecture The Advantages & Disadvantages It Presents CC PublicDomainPictures
  2. 2. Cloud Computing Continuously growing! Services available without need of powerful PCs Devices like smartphones can access easily CC GoodNCrazy
  3. 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. 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. 5. Coming Changes From Hard Disk …To Solid State Drives Drives…CC Simon Wüllhorst
  6. 6. Data Management Shift from home desktops towards next-gen data centres Database management systems needed to control cloud capabilities CC IntelFreePress
  7. 7. “Cloud computing provides environments to enableresource sharing in terms of infrastructure, middlewareand application development platforms.” CC theaucitron
  8. 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. 9. Infrastructure Resources Includes “computing power, storage and machine provisioning” CC Kinologik CC Google
  10. 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. 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. 12. Business Processes Use their own internal applications to reduce third party dependency
  13. 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. 14. Data Storage Data has to be stored in a hard format somewhere Security needs to be provided for this lydia_shiningbrightly CC
  15. 15. Data Access Hackers are potential threat Cloud providers need to control access to data CC gpuhackr
  16. 16. Data Classification Data must be separated Data should be encrypted for security CC mcfarlandmo
  17. 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. 18. A “Killer App” Yet to be developed Various barriers in the way
  19. 19. The Future… If it can be imagined, it can be perfected Huge potential in the coming years… backofthenapkin CC
