1. .NET 4.0 & Cloud ComputingSimplifying the Life of Developers Dhirendra Singh Director - Technologies TrivialWorks solutions

3. AgendaWindows Server AppFabric .NET ? .NET 4.0 WPF WCF Cloud Computing

4. About me More than 8 yrs. Of experience in Enterprise application development I have executed several projects for Motorola, Seagate, Cognizant , Barclays Europe & Pacific Golf, Japan. Handled clients & worked in several geographies like London (UK) Tokyo (Japan) Malaysia Joined TrivialWorks Solutions as Managing Partnerand Director - Onshore communications. Customized & architected .NET frameworks like .NET 2.0/3.0/3.5/4.0, WCF, WPF & Cloud based applications.

5. .NET ? .Net is a framework for developing web-based, windows-based, Service based & now Cloud based applications within the Microsoft environment. The framework offers a fundamental shift in Microsoft strategy: it moves application development from client-centric to server-centric.

6. .NET Application .NET Framework .NET – What Is It? Operating System + Hardware

7. Framework, Languages, And Tools VB VC++ VC# Visual Studio.NET JScript … Common Language Specification ASP.NET: Web Services and Web Forms WindowsForms ADO.NET: Data and XML Base Class Library Common Language Runtime

8. Compilation in .NET Code in VB.NET Code in C# Code in another .NET Language VB.NET compiler C# compiler Appropriate Compiler IL(Intermediate Language) code CLR just-in-time execution

9. Intermediate Language (IL) .NET languages are not compiled to machine code. They are compiled to an Intermediate Language (IL). CLR accepts the IL code and recompiles it to machine code. The recompilation is just-in-time (JIT) meaning it is done as soon as a function or subroutine is called. The JIT code stays in memory for subsequent calls. In cases where there is not enough memory it is discarded thus making JIT process interpretive.

13. New Generation Internet MegaService Backend App Web site Backend App Web site Loosely-coupled, services connected by XML-based messages and contracts, written in many languages Service Service MegaService XML-msgs Service Web site Device Service

14. Lets have a look on more features & technologies !

15. .NET At The Core

16. Windows Presentation Foundation (WPF)

18. Themes

19. Unified programming model

20. Declarative programming

22. What’s Windows Presentation Foundation? Next generation presentation subsystem for Windows Unified programming model Harness the power of new graphics hardware Provide designers direct input into project development Enables developers and designers to create visually stunning user interfaces

23. DirectX HTML HTML GDI+ Win Forms Word GDI Web Forms PDF MFC VB Forms Media Player WPF: Programming Model Unification Unified WPF API Documents User Interface Media

24. WPF: Using the Hardware Vector-based composition engine uses the PC’s graphics power Quality is preserved with scale CPU freed from graphics work Gain capability from graphics card advances

25. 2D Graphics, 3D Graphics, Imaging 2D Graphics Imaging 3D Graphics

26. <Border Width="400" BorderBrush="Green" BorderThickness="9"> <StackPanel> <MediaElement Source="aero.wmv" /> <Button>Hello</Button> </StackPanel> </Border> Audio & Video Formats: WMV, MPEG, Some AVIs Can be synchronized with animations Windows Media Foundation used to instantiate playback machinery into a DirectShow graph

27. ClearType & Antialiasing Sub-pixel positioning & natural widths

29. Declarative Programming through XAML

30. Third Party Tools (e.g. Aurora by Mobiform, ZAM 3D by Electric Rain)With XAML designers & developers can streamline their collaboration Designers design Developers add business logic

31. Write Once…. & use everywhere ! WPF enables you to write the code in XAML and you are free to host it into Web browser Mobile widgets Windows Applications

32. No worries for Designer tools… http://www.microsoft.com/products/expression/en/default.mspx

33. This is fine…. Now lets try another…. WCF (Windows communication Foundation)

34. From Objects to Services Object-Oriented Polymorphism Encapsulation Subclassing 1980s Component-Based Interface-based Dynamic Loading Runtime Metadata 1990s Service-Oriented Message-based Schema+Contract Binding via Policy 2000s

35. The Challenge Radically Simplifying Distributed Application Development Development of connected systemsremains costly and frustrating Different programming models for different tasks Need for security and reliable messaging Interoperability with applications on other platforms Productive service-oriented programming model needed

36. Windows Communication Foundation Unified framework for rapidly building service-oriented applications

37. What Does WCF Replace?

38. Services and Clients Message Client Service Message

39. Endpoints Endpoint Endpoint Endpoint Client Service Message

40. Address, Binding, Contract Endpoint A B C A B C A B C Client Service Endpoints Message Address Binding Contract (Where) (How) (What)

41. Ways to Talk One Way Client Service Request-Reply Duplex (Dual) One Way: Datagram-style delivery Request-Reply Immediate Reply on same logical thread Duplex Reply “later” and on backchannel (callback-style)

42. So … we are now well versed with these terms ! WPF WCF LINQ SOA XAML C#, XML .NET Framework

43. What’s very new…?

44. An Introduction toCloud Computing

45. The challenge Add new services for your users quickly and cost effectively

46. Expand your Infrastructure! Buy new servers, increase your software costs, provision more datacenter capacity!!

47. Look to the cloud! Pay for the bandwidth and server resources that you need. When your push is done then turn the whole thing off!

48. 3 Pillars of Cloud SaaS (Software As a Service) PaaS (Platform as a Service) IaaS (Infrastructure as a Service)

49. Examples CRM Financial Planning Human Resources Word processing Commercial Services: Salesforce.com emailcloud SaaS

50. Examples Google App Engine Mosso AWS: S3 PaaS

51. Examples Flexiscale AWS: EC2 IaaS

52. Advantages Lower cost of ownership Reduce infrastructure management responsibility Allow for unexpected resource loads Faster application rollout SaaS PaaS IaaS

53. Common Factors Pay per use Instant Scalability Security Reliability APIs SaaS PaaS IaaS

55. Questions?

56. I have two more words to say...!

57. Thank You !!
