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? •ISO/IEC TS 22237-1:2018 — Data centre facilities and infrastructures — Part 1: General concepts •ISO/IEC TS 22237-2:2018 — Data centre facilities and infrastructures — Part 2: Building construction •ISO/IEC TS 22237-3:2018 — Data centre facilities and infrastructures — Part 3: Power distribution •ISO/IEC TS 22237-4:2018 — Data centre facilities and infrastructures — Part 4: Environmental control •ISO/IEC TS 22237-5:2018 — Data centre facilities and infrastructures — Part 5: Telecommunications cabling infrastructure •ISO/IEC TS 22237-6:2018 — Data centre facilities and infrastructures — Part 6: Security systems •ISO/IEC TS 22237-7:2018 — Data centre facilities and infrastructures — Part 7: Management and operational information

- 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 -documents -music -video https://animoto.com/ www.canva.com
- 42. Interlude
- 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 Future proof your business model
- 49. Group discussion
