Presentation on Cloud Computing by Kevin Nicholson for CT231 module, 2BCT

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

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

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

7. “Cloud computing provides
environments to enable
resource sharing in terms of
infrastructure, middleware
and 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

9. Infrastructure Resources
 Includes “computing power, storage
and machine provisioning”

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

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…
