Fraser Henderson hosted a webinar about cloud computing. The webinar covered: - Definitions of cloud computing and how it provides flexible, low-maintenance computing services over the internet. - The history and enabling technologies that led to cloud computing. - Common uses of cloud services like storage, backup, disaster recovery, email, and software as a service. - Considerations for moving to the cloud like costs, limitations around network connectivity and vendor lock-in. - Emerging areas like edge computing, integration of cloud services, and how cloud services can support collaboration. - The future of cloud computing in areas like machine learning, serverless architectures, and everything connecting to the network.

5. What is “cloud computing”? Computing services over the
internet “on-demand” as PAYG
“Outsourcing of everything!”

6. What is “cloud computing”?

7. What is “cloud computing”?
Flexible
Low maintenance
“Worry-free”
Transfer of risks
Quick to start

8. How did it come about?
Centralisation versus
decentralisation

9. Enabling technologies
+ Managed centres
+ Emulation
+ Fast internet

10. Top uses for cloud computing
Backup as a service (BaaS)
Disaster Recovery as a service (DraaS)
Email
Virtual Desktop (DaaS)
Big Analytics
Software as a service (SaaS)

11. Use case (owned)
$$$
Energy
Utilisation
Half-life of hardware

12. Use case (rent) $

13. Examples of cloud storage
ADS
$$

14. Different types of services

15. Different types of services

16. Space saving
Benefits Reduced management &
operating costs
No updates
Reliability
Elasticity
Security
Economies of scale
(environmental)
Data backup
Sharing data
Rapid set-up

17. Limitations
Information theft or
interception
(remote storage and
transmission)
Network connectivity
dependent (constant!)
Latency
Vendor “lock-in”
Hard to control, reliant
on support
Hard to integrate
Ability to
innovate
Fail
sometimes

18. Interlude

19. Data processing (think speed!)
Data Centre
Collect/store
Aggregate
Analytics
Control flow
Edge computing
Immediacy
Local storage & processing
Make local decisions

20. Edge computing example
On-device
recognition
Cloud based
speech
and response
DAC and

21. Integration & The API - waiter
Kitchen versus you
They charge $0.25 per 1000 API units

22. Bring Your Own Device (BYOD)
Use own devices to access company
networks. Device liberty!
Mobile device
management (MDM)
software

23. Reliability & resilience
“Reliability isn’t a new problem, but the cloud
gives us someone else to blame”

24. Scaling

25. Not always economical
12TB = c.£220 per month

26. Energy=cost
Thin/zero clients consume 6 to 50 watts of electricity while
normal desktop computers consume 150 to 350 watts

27. Interlude

29. Pricing cloud services
Egress outbound
data to world
Ingress – outside
world in

30. Example costs (BM, York) For an average page size of 50KB,
20,000 visitors per month, and 5
pages per visitor your website will
need about 5000MB, or 5GB, of
bandwidth per month. Note that
20,000 visitors per month equates to
approximately 667 visitors per day.
This is a number even most large
websites cannot achieve.

31. Super low cost experimentation
Godaddy.co.uk
CJC1HOS1
£12 for 12 months, including free
domain name

32. Define cloud solution requirements
Define the hardware (choose the computer service Win/Linux/Storage/Bandwidth
Define encryption
Management controls (monitoring)
Quota
Security policy
Data centre – where can data be stored?
Your requirements

33. SLA’s
Money back guarantee?
How will data be kept confidential?
Will I be affected by “scheduled” downtime?
What are support severity levels and guaranteed response times?
Is my data protected by backup and restore routines?
Where are you data centres?
How is my data protected against disaster events?
Will I still own my data?
What about price increases?
How green is my hosting?

35. Visual cloud
Consumers in streaming-
capable homes in the U.S. now
spend 25% of their TV
time watching streaming video
content
About 80% of U.S. consumers
now subscribe to at least one
paid streaming video service.

36. Visual cloud

37. Quality as a differentiator
Netflix sends out multiple quality bit streams for each
stage of video quality (SD, HD, UHD) for each title and in
this they are removing the highest bandwidth stream.
“.. additional compression will be
applied to their video streams and so
you may notice more distortion in the
image quality.”

38. Cloud licensing
What happens when licenses
are revoked?
What happens when multiple
devices are used (check-in and
check-out)

39. Video rendering
Don’t underestimate the
benefits of collaborative
working

-music
-video

43. The future
A quantum machine has significant
implications in areas like artificial
intelligence. It actually makes today’s
most powerful supercomputers look like
toys. The Google device performs a
mathematical calculation in fewer
than three and a half minutes. In
comparison, a modern supercomputer
would require more than 10,000 years to
complete the calculation. That’s not all.
“Tomorrows
technology is here
today, it’s just not
evenly distributed”

44. The future
Online security firms
Data analytics firms (from storage)
Internet of Everything
Digital Nomads (location
independence)
Rental business models
Community clouds

45. Cloudonomics – not really centralisation!
Law #1: Utility services cost less even though they cost more
Law #2: On-demand trumps forecasting. Utilisation and deprovision!
Law #3: Aggregate demand is smoother than individual.
Law #4: Economies of scale (e.g. heating/bandwidth)
Law #5: Superiority in numbers is the most important factor in the
result of a combat (Clausewitz).
Law #6: Don’t put all your eggs in one basket.

46. The future : insights
Machine
learning and AI
will
help identify
data patterns
that have an
impact on the
business.

47. The future : embrace
Serverless – pricing depends
on resources used by an
application

48. The future
Lower cost
>Virtual machines
>Storage
Enhanced performance
>Reduced latency
>More reliable
>Faster
New offerings
>Powerful data analytics
>Price per function call
>DaaS
A cycle
>More edge technology
>Everything will be the network
