From Real to Virtual: Why Computing is Shifting Online
- 1. FROM REAL TO VIRTUAL AND WHY EVERYTHING IS GOING THAT WAY
- 2. THIS IS A STORY about how computing changed from a box on your desk that did things for your boss, into virtual pieces whose location no longer interests us.
- 3. AND WHY it will probably effect ownership of everything.
- 4. HERE IS MY CAR: AFTERNOON
- 5. THE LIFECYCLE of an old desktop computer was 1) buy, 2) use, 3) then throw away. And it spent most of the time inactive
- 6. SETI@HOME SETI@home is a scientific experiment that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data.
- 7. IN THE PAST We shared time on computers
- 8. WHAT IS A COMPUTER
- 10. WHAT IS COMPUTING? 10 PRINT “HELLO!” 20 GOTO 10
- 12. HERE IS MY CAR EVENING
- 15. REAL COMPUTING • image compression • Simulate a very dense neural network mimicking brain functionality of a lower class organism. • Statistical analysis (volatility and return, correlation) • Portfolio optimization
- 16. THE DATACENTRE Located in Uitikon, Switzerland, the data center is expected to create 2,800 megawatts of wasted heat per year when operating at full capacity
- 17. AMAZON SOLD THINGS ON A WEBSITE “Excess computing capacity from their ecommerce site that was used as the basis for Amazon Web Services' (AWS) cloud.” (Not quite true) “..consider how Amazon’s infrastructure could more efficiently scale up. They explored how abstraction and decoupling the applications from the infrastructure could make it easier to manage.” (Benjamin Black)
- 18. AMAZON AWS • Public computing, based on private need • Rent virtual, as long as it is ‘up’ • Identify yourself • Security • Geography • Command line
- 20. CONTAINER
- 21. CONTAINERS
- 22. CONTAINER SHIPS
- 23. WARDLEY MAP
- 24. WARDLEY MAP
- 26. AS A SERVICE
- 27. AWS LAMBDA AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running.
- 28. HERE IS MY CAR ROAD TAX INSURANCE AGE EXPOSURE
- 29. WHAT IS UBER’S BUSINESS MODEL? Uber is a smartphone app which provides on-demand service to users. It connects willing passengers to taxi cab drivers. Taxi drivers use their own cars when providing taxi service and Uber gets 20% of the fare.
- 30. WHAT IS AIRBNB’S BUSINESS MODEL Airbnb utilizes a platform business model. This means they facilitate the exchange between consumers (travelers) and producers (homeowners). Because the consumers aren’t Airbnb ‘employees’, and because there’s practically an infinite number of homes that could potentially go up on the site, Airbnb can scale at an incredibly fast rate at zero marginal cost. (Quora answer)
- 31. THANKS TO THE INTERNET • Increased utilization from sharing • Scale with little cost to business • Platform is a market • Disruption for traditional models
Editor's Notes
- Introduce!
- In fact computers did little computing, basically just ‘office equipment’. My mum had a laptop, when men didn’t want one
- The same forces that effect computing actually effect all resources
- Stationary, empty, and not doing anything
- It was off for at least 12 hours, but even during the office day, it did very little computing. Typewriters use no power while off
- As if to prove the point, there were projects to productively use your computing while it was idle -1999
- Computers were dumb terminals which shared one central processer. A bit like a browser on its own.
- Most of the bits that are on a computer don’t do computing, most are input / outpiut peripherals
- Instruction register, program counter, programme state register, memory, and maths bits
- Format, Purpose, output, direction, instruction, data, redirection
- Format (5,7,5), purpose (seasonal), data, symbolic translation in brain – rules structure and convention -– one person writes, one person ‘computes’
- Still not doing anything
- A computer is really just storage, compute and network – racks. This leads to the idea of a virtual computer not at your desk
- Distributed – you may get the bits from several sources. We are probably talking about rack based servers
- Problems that need you to revisit previous calculations
- Computing isn’t actually free, it does take up a lot of power. Also damage from heavy use.
- All in about 2003
- Amazon had to cover the concerns for the public of renting computing
- This slide shows the notional space on a virtual. But also looking at the shell there is no difference amazon cloud drive
- Instead of thinking about an entire virtual machine, just share the operating system and have your own ‘flat’. Docker!
- Container of containers – containers share some commons, but keep private contents
- Simon Wardley, COO Fotango,view share and print photos, Canon bought them – then he resigned in 2007
- What is secret source, what is now utility (replace)
- Hospitals have their own generators. Mostly as back up; but not a sensible business decision to be independent of cheaper power
- Map of the service model changing
- Increased utilization of my car, use internet to make a market, the car is now a service
- Do you need to own a home
- Computing can now occur everywhere and anywhere, in any device
