The document discusses cloud computing as a model providing on-demand access to shared computing resources, highlighting its evolution from products to services. It emphasizes the benefits of an open cloud initiative, which promotes user and vendor freedom, the significance of open standards, and the establishment of community-driven principles for cloud services. The document also outlines current challenges, such as the need for standards and specifications for cloud workloads.

2. what is cloud?

3. cloud computing is a model for enabling convenient, on-
demand network access to a shared pool of
configurable computing resources (e.g., networks,
servers, storage, applications, and services) that can be
rapidly provisioned and released with minimal
management effort or service provider interaction.

4. cloud computing is the delivery of computing as a
service rather than a product, whereby shared
resources, software, and information are provided to
computers and other devices as a utility (like the
electricity grid) over a network (typically the Internet).

5. common theme
product » service

6. @beaker
products

7. service
intangible equivalent of an economic good

8. utilities
electricity, water, gas, telephone

9. generators (product)

10. grid (service)

“If computers of the kind I have advocated become the
computers of the future, then computing may someday
be organized as a public utility just as the telephone
system is a public utility... The computer utility could
become the basis of a new and important industry.”
— john mccarthy, 1961

12. disruptive innovation

15. future?
“I think there is a world market for maybe five
computers.” — thomas watson, ibm, 1943

16. why “cloud”?

17. demarcation
separation of duties between provider and consumer

18. benefits
multi-tenancy, economy of scale » secure, reliable, scalable

19. tight coupling
legacy » integration

20. loose coupling
cloud » aggregation

26. open source
uses copyrights to open products

27. software licenses
have service provider “loophole”

28. close loophole?
affero general public license (agpl)?

29. no thanks.
do you really expect the source code for Gmail?
could you use/modify it if you had it?

30. open cloud
ensures openness for services

31. user & vendor freedom
freedom to migrate (for users)
freedom to make money (for vendors)

32. commoditisation
undifferentiated price competition
standards create tradable commodities (GB/m, CPU/h)

33. standard workload?
no “electron” for the cloud — 240v/50Hz is simple API
“apulettes” = code + data packets?

34. open formats
e.g. Open Document Format (ODF)

35. open interfaces
e.g. AtomPub

36. open formats +
open interfaces
= open cloud

37. open standards
copyrights + patents + trademarks + open source impl.

38. open cloud initiative
a california non-profit — 501(c)3 status pending

39. open cloud principles
like an open source definition for services

40. community consensus
development & application of open cloud principles

41. board of directors
5-21 industry leaders

42. subcommittees
governance, administration, certification, etc.

43. current status
awaiting development of standards (not an sdo)
currently no standards - only specifications

44. wishlist
smtp for cloud workloads

45. http
no need for new transfer protocol (http vs smtp)

46. discovery
/robots.txt » /.well-known/
Defining Well-Known URIs (RFC 5785)

47. enumeration
text/uri-list? json? xml?

48. annotation
“semantic” http headers? json? xml? in-band?

49. transfer
http: mime-types, security (c/i/a), etc.

50. roadmap
move, copy, catalog, etc.
