2. From the Web to the Cloud
• Computing history – pre 1993
• Web 1.0 - 1993 world-wide-web
• Web 2.0 - 2001 - user-created content
• Web 3.0 – 2009 – utility/cloud computing?
• Cloud Computing
– What’s under the hood?
– Where are we now?
– Where are we going?
• Questions

3. Pre 1993 Computing
• Mainframes 1960s
– IBM, CDC, HP, DEC, Amdahl
• Mini-Computers 1970s
– DEC, Xerox
– ARPANET, UNIX, email
• Personal Computer 1980s

5. First IBM PC
The main features that the IBM PC initially
gave were as follows:
•One or two 360k 5.25" floppy drives (early
models had 120k byte single sided drives).
•BASIC in ROM with cassette tape support.
•Option of CP/M-86 or IBM PC-DOS.
•Wide range of off-the-shelf software eg
VisiCalc, Wordstar, SuperCalc, dBase II,
which were easily ported from 8-bit CP/M.
•Open platform for new software
developments, from 8086 Assembler to a
wide range of programming languages (eg
PL/M, C, Basic).
•Choice of either a high-quality monochrome
text display or colour display capable of 2-
colour medium resolution or 4-colour low
resolution graphics.
•Published hardware bus and layout design,
allowing 3rd party add-ons.
•Options of serial and parallel printer ports.
•IBM on the front, hence world-class sales
and marketing support.

6. Web 1.0
• 1984 – GNU project to develop and promote Open Source
Software launched by Richard Stallman
• 1990 – HTTP protocol and first WorldWideWeb interface
designed and released by Tim Berners-Lee, CERN
• 1991 – Linux released by Linus Torvalds
• 1993 – First browser – Mosaic – Marc Anderson NCSA, later
became first commercial browser – NetScape – then open-
sourced as Mozilla (now Firefox)
• Search engines – 1990 – Archie; 1993 – Excite; 1994 – Lycos,
AltaVista, Webcrawler; 1996 – Intomi; 1997 – Ask Jeeves (now
ask.com); 1998 – Google launched; 2004 – Google went public

7. Web 2.0 - User Created Content
• 2001 – Wikipedia
• 2002 – Friendster
• 2003 – MySpace
• 2004 – Facebook
• 2005 – YouTube
• 2006 – Blogger fully supported by
Google (blogging started in 1980s-1990s)
• 2006 – Twitter started

8. Web 3.0 – cloud computing?

9. What is Cloud Computing?
CLOUD: Common, Location-independent, Online Utility provisioned on-Demand
• Common, in that it multiplexes demand from multiple customers and
applications into a shared, common pool of computing resources.
• Location-independent, because data accessibility should follow you no matter
where you are.
• Online, in the sense that it is accessible over an agile, geographically dispersed
network, that is available anytime.
• A Utility because it provides value and offers usage-sensitive, pay-per-use
pricing.
• on-Demand in that the ability to provision capacity or service should be as fast
as possible to meet variable demand requirements, enhancing business agility
and providing capacity and scalability at the lowest total cost.

Solutions, AT&T, November 2008

20. What’s under the hood?
• Layers
– SaaS – Software as a Service
– PaaS – Platform as a Service
– IaaS – Infrastructure as a Service
• Virtualization
• Enterprise and/or open or hybrid
• Distributed connected data centres
• Green IT

21. Where are we now?
• Many SaaS applications, some PaaS
• Amazon, Rackspace, VrSTORM IaaS
• Apps.gov – launched Sept 15, 2009
• Websphere (IBM), Sharepoint (Microsoft), VMware,
Citrix – big corporate support for common portals and
clouds
• VrSTORM – first open Canadian cloud solution
provider
• Alberta cloud-based companies: Replicon, MoboVivo,
Clinitrust, Kanata Health Solutions, Calgary Scientific,
Cambrian House
• High on hype cycle
• Lots of creative destruction

22. Where are we going?
• Most businesses and applications only
need very lightweight end-point devices
• Almost all applications will be deployed
to the cloud
• Consider moving your applications to
the cloud
• Decreased capital costs and operations
• Cloud utilities will provide competitive
packages based on pay-per-use
