A view on architectural considerations and models for the emerging context of software plus services and in view of technologies such as Windows Azure.

1. Software + Services Mark Bloodworth, Architect, Microsoft
Marc Holmes, Architect, Microsoft

2. In The Beginning

3. “…it would be shortsighted to focus only on shifting IT services away from on-
premises implementations. Instead, the ability to choose how an IT service is
delivered from on-premises data centers to private clouds, off-premises utilities
or even the public cloud is most critical.”
Gartner Cloud Computing Report Series, June 2008
“This (cloud computing) is a new way, but it’s not going to replace the existing –
on-premise software is not going to go away.”
Paul Slakey, Google, May 2008
“One of the key challenges for corporate IT departments, in fact, lies in making
the right decisions about what to hold onto and what to let go”
Nicholas Carr, The Big Switch

The pressures on architecture

12. Architecture is growing

13. Scope started small

14. And got bigger

15. And bigger

16. And now we need to reach the whole web

17. If we get this wrong

18. Considering the zeitgeist

19. User Experience matters

20. New devices are emerging

21. One size does not fit all

22. Where should processing be done?

23. • Audiences • Form Factor
UX
• Domain
Devices • Capability
• Multi-user
• Scale
• Scope
Size • Importance
• Desktop
• Datacentre • Integration
Process • Cloud
• Hybrid

39. Principles to support the model

40. Experiences should span devices

41. Federations of loosely coupled co-operating systems
and loosely coupled compositions

42. Infrastructure and solutions should extend from server
to cloud

43. Practical stuff to do

44. The Right Team

55. • Cloud computing is becoming real
• Software plus Services is about choice
• Software plus Services is about the right architecture
