2. Growth of Cloud Computing & Social Enterprise
3. Growth of Cloud Computing
4. Cloud Computing will be a $ 241 billion mkt by 2020
5. Market Cap of Top Cloud Computing Companies Name (Ticker) Market Cap (Billions ) Stock Price ($) Key Product(s) Google (GOOG) $160 B $495.52 G App Engine Amazon (AMZN) $96.23 B $211.98 AWS Vmware (VMW) $33.31 B $78.89 Server Virtualization Salesforce (CRM) $15.16 B $111.91 Force Platform NetApp (NTAP) $12.39 B $33.64 Storage RackSpace (RAX) $31.49 B $31.49 Cloud Services

7. Facebook Members (Growth of Social Networking) !   More than 500 million active users !   over 900 million objects (pages, groups, events and community pages) !   About 70% of Facebook users are outside the United States 9 Novembre, 2010 2010 IUT Cloud Computing Seminar 7
8. Architecture for the Real World
9. Your Data Model Your business logic Data Layer Application Logic User Interface Screens exposed to the end users
10. Idealized Situation
11. How are your opinions? !   What do you like most? !   What do you like least? !   What kinds of difficulties have you had? !   What do you think the real world is like?
12. Small Problem – Easy Fix
13. Just lift the car out of water
14. Initial Disappointment
15. Bring on Heavier Equipment
16. Whoops, That too was a surprise!
17. Guess what’s next?

20. More Examples Source: from Internet
21. 1st attempt at reinventing the wheel
22. Reinvent the wheel is tougher than you think
23. Classic Approach Meets Classic Problems !   Too Simplistic !   Linear model !   Inflexible !   Static Input / Output !   Either Quality, Time, or Cost Read my blog - http://www.are4.us/?p=815
24. Lean Approach – Smart Learning
25. Data Store is everywhere !   Browsers (Chrome, Firefox, IE, Opera) !   Mobile devices (Iphone, Android, Blackberry, Windows CE, Symbian) !   Adobe Flash Applications !   Desktop Applications !   Game Consoles, !   Everywhere !!!
26. Meshed Architecture (Macro View ) Community Data Models
27. Growth of No-SQL DBs
28. Some Causes !   SW developers are not natural born DBAs !   Developing a good data scheme is pretty tough !   Convince your partner to use your DB scheme is tougher! !   DB administration could be a full time job !   Backup !   Security !   Profiles ! Etc
29. Mesh Architecture (Micro view) High Perf Data Services (No-SQL, In-Memory Cached Objects) Additional Data Sources
30. Benefits of Ruby on SF !   There are lots of incentive to use Ruby !   Tools for building web-apps (ERB, HAML, Markdowns) !   Methodology (BDD – Cucumbe, Rspec, Shoulda) !   Testing (Webrat, Capybara, Unit Testing) !   Ease of Deployment & code version & collaboration (Git) !   Extensive Code libraries – Github & RubyGems !   Many more
31. History of Ruby on Salesforce !   Version 0 – API era !   Version 1 + 2 (REST + SOAP) – Force.com Era !   Version 3 – (Pure REST) Database.com era
33. Salesforce Social Platform
34. Example App – Ruby Social Network Updater
35. The Datbase.Com GEM !   Covers both Sobject & Chatter API !   Full CRUD on DDL side !   Support: !   User-name password !   Security token ! Oauth Flow
36. Basic Steps !   Use the GEMs !   Create a client with Consumer key + secret !   Authenticate (3 options) !   Materialize an Sobject + set Namespace (module name) !   CRUD operation on the object !   Form-building attributes
37. Use the Gem ! Add GEMs to Gemfile !   gem 'databasedotcom' !   gem 'databasedotcom-rails’ (optional) !   Run bundle install
38. Initialize the client !   # configure client id/secret explicitly # client = Databasedotcom::Client.new :client_id => "xxx", :client_secret => "yyy" !   # configure client id/secret from a YAML file # client = Databasedotcom::Client.new "databasedotcom.yml" !   # configure client id/secret from the environment # client = Databasedotcom::Client.new
39. Authenticate !   # authenticate with a username and password client.authenticate(:username => "wayne@manor.com", :password => "arkham") !   # authenticate with a callback hash from Omniauth client.authenticate(hash_from_omniauth) !   # authenticate with an externally-acquired OAuth2 access token client.authenticate(:token => "whoa-that-is-long")
40. ! client.materialize("Contact") ! Contact.attributes #=> ["Name", "Company", "Phone"] ! ron = Contact.find("rons_id") !   puts ron["Company"] #=> "The Olde Company, Inc." ! ron["Company"] = "Some New Gig, LLC" ! ron.reload["Company"] #=> "The Olde Company, Inc." ! ron["Company"] = "Some New Gig, LLC" ! ron.save ! ron.reload["Company"] #=> "Some New Gig, LLC" Materialize a SObject Class CRUD operations
41. Form-building attributes ! Contact.label_for("Phone”) #=> "Phone Number” ! Contact.picklist_values("Honorific") #=> ["Mr.", "Ms.", "Dr."]
