3. Ugh. Not another presentation about
how great cloud computing is…

4. I hear you, man.

5. This is a talk about change…

6. …a talk about the effects of
cloud computing on the
future of IT.

7. It’s about evolving to support net
new application categories that are
transforming business.

8. Data analytics (aka “Big Data”)

9. The Internet of Everything

10. IaaS, PaaS and SaaS

11. The buzzwords!
Make them stop!!!

12. This is a talk about the switch from
infrastructure centric operations to
service and application centric
operations.

13. Not…

14. Server Network Storage

15. but…

16. Application Operations
Service Operations
Infrastructure Operations

17. Let’s look at why…

18. Before self-service resource
provisioning (aka cloud), IT was
asked to make computing work…

23. But cloud computing asks IT to do
something different…

27. Developers building to new models
are asking IT to deliver computing
as a set of services…

29. What do you mean “service”? I
already provide “service”…don’t I?

30. Heck yes…but no.

31. (Well, probably not…)

32. “Service” in this context is…

33. Software Software Software
(Typically Distributed
And Scalable)
Some
well-
defined,
relatively
granular
software
componen
t

34. Software Software Software
(Typically Distributed
And Scalable)
E.g. a
RDBMS or
NoSQL
endpoint, a
telephony
service, Ia
aS
automation

35. Software Software Software
UI
Sometime
s with a
user
interface…
Optional, actually…

36. Software Software Software
API UI
…but
always
with an
API.
Required.

37. Software Software Software
API UI
Catalog
Frequently
(but not
always)
made
available
via a
catalog or
mgmt
service.

38. Software Software Software
API UI
Catalog
E.g.
Apigee
Mashery
Layer7
Etc.

39. Why APIs?

40. Because a key role of services is
enabling integration.

41. Composability

42. Think Unix command line tools

43. An exercise…

44. Read a file of text, determine the n
most frequently used words, and
print out a sorted list of those
words along with their frequencies.

45. tr -cs A-Za-z 'n' |
tr A-Z a-z |
sort |
uniq -c |
sort -rn |
sed ${1}q

46. None of those Unix commands
were designed with that problem in
mind…

47. Yet they work together beautifully to
solve the problem.

48. So, how does an IT organization get
started down this path?

49. Application Operations
Service Operations
Infrastructure Operations

50. Infrastructure Operations
 Build a common infrastructure for future
service deployment and operations
 Cisco UCS, etc
 Likely SDN in the future (e,g.
OpenDaylight)
 Provide APIs for infrastructure itself wherever
possible
 OpenStack/CloudStack/Eucalyptus, etc
 Cisco ONE, Juniper Junos API, etc

51.  Identify key services required by developers
and application owners/operators
 IaaS
 PaaS
 Look for supporting services
 Billing/chargeback/showback
 Monitoring/Auditing/Security
 Catalog for discovery
Service Operations

52.  Get multi-cloud management
 This is about consuming services, not delivering
them
 Agility, governance and choice critical here
 DevOps
 Remember that the end users are probably
developers and “super users”, not traditional
system administrators.
 Lot’s of prebuilt/tested “stuff”
Application Operations

53. Yay! All my problems are solved!

54. Not likely…

55. Seek advice and iterate.

56. Thank you.
