A look at Windows Azure and Cloud applications, and how they affect how we develop software.

1. Considering Windows Azure: Exploring questions related to cloud applications based on practical experiences.

2. Nicklas Andersson Chief Technology Officer, eCraft

3. Cloud Computing is being insanely hyped right now.

4. Sooner or later you'll have to understand or explain Cloud Computing and Windows Azure.

5. The hype is obscuring the real value.

6. You need to understand how building applications for Windows Azure is different.

7. Let me share some of my experiences of Windows Azure and Cloud applications with you.

9. What is Innovation?

10. The purpose of the innovation process is to turn good ideas into money.

13. What the Cloud promises is very compelling from a business point of view.

14. Cloud Computing promises to cut IT costs.

15. Unless you are a hosting company it's not your core business to own hardware.

16. Fact: Computers break because dirty people touch them.

17. There's lots of infrastructure and services that need to be in place for a high-perf. application.

18. The Cloud promises to enable new business models and opportunities.

19. The Cloud and Software as a Service belong together.

20. You can succeed or fail with less risk.

21. You are no longer hindered by the speed of your IT-department.

22. The Cloud promises to be key to the next growth period for our industry.

27. Most of the growth periods in our industry have started in someone's garage.

28. High hardware and infrastructure costs are limiting inventors.

29. What the Cloud promises is very compelling from a business point of view.

30. Windows Azure applications follow a strict architectural pattern.

32. You are not moving your existing physical architecture to the cloud.

33. Therefore your logical architecture needs to be rethought as well.

34. A lot of the time our logical architectures are affected by the tools we use.

35. Your current approach to testing might not be so easy to adapt to the Cloud.

36. High-performance applications are hard, and few people have experience building them.

37. In Windows Azure applications are architected for scalability.

38. Being able to scale the front end and the back end separately is a great advantage.

39. The front end and the back end communicate asynchronously. Which is hard to develop for.

40. We need to rethink how and why we persist data.

41. Why are we so focused on databases anyway?

42. Microsoft has introduced a cloud data offering through Azure SQL Services.

43. The first offering, SQL Data Services, is not a relational database in the traditional sense.

44. Cloud application need to be extensible per tenant. Traditional DB:s don't make that easy.

45. Currently Windows Azure forces you to roll your own persistence layer.

46. Windows Azure applications follow a strict architectural pattern.

47. Not all applications can easily be mapped to the Windows Azure architecture model.

48. Let's admit it, we take shortcuts when we build applications.

49. We mix our presentation layer with our data layer.

50. Our applications don't always have a clear separation of concerns between modules.

51. And in all honesty, the tools and most samples make it almost too easy to get it wrong…

52. Windows Azure is intended for bulk technologies.

53. The mainstream web front ends, like ASP.NET with Ajax and Silverlight.

54. You can use services based on WCF.

55. Anything that requires a separate installation is out.

56. Some applications aren't suited for Azure, or not worth the effort.

57. Obviously applications that require a close proximity to specific other applications.

58. Applications where you've invested heavily in tools.

59. Applications that need to do a lot of data aggregation.

60. Not all applications can easily be mapped to the Windows Azure architecture model.

61. Sooner or later you'll have to understand or explain Cloud Computing and Windows Azure.

62. You need to understand how building applications for Windows Azure is different.

63. Let me share some of my experiences of Windows Azure and Cloud applications with you.
