Ugh. Not another presentation about how great cloud
computing is…
I hear you, man.
This is a talk about change…
…a talk about the effects of cloud computing on
the future of IT.
It’s about evolving to support net new application categories that are transforming business.
Data analytics (aka “Big Data”)
The Internet of Everything
IaaS, PaaS and SaaS
The buzzwords!Make them stop!!!
This is a talk about the switch from infrastructure centric operations to service and
application centric operations.
Not…
Server Network Storage
but…
Application Operations
Service Operations
Infrastructure Operations
Let’s look at why…
Before self-service resource provisioning (aka cloud), IT was
asked to make computing work…

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

What do you mean “service”? I already provide “service”…
don’t I?
Heck yes…but no.
(Well, probably not…)
“Service” in this context is…
Software Software Software
(Typically DistributedAnd Scalable)
Some well-defined, relatively granular software component
Software Software Software
(Typically DistributedAnd Scalable)
E.g. a RDBMS or NoSQL endpoint, a telephony service, IaaS automation
Software Software Software
UI
Sometimes with a user interface…
Optional, actually…
Software Software Software
API UI
…but always with an API.
Required.
Software Software Software
API UI
Catalog
Frequently (but not always) made available via a catalog or mgmt service.
Software Software Software
API UI
Catalog
E.g.
Apigee
Mashery
Layer7
Etc.
Why APIs?
Because a key role of services is enabling integration.
Composability
Think Unix command line tools
An exercise…
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.
tr -cs A-Za-z '\n' |tr A-Z a-z |sort |uniq -c |sort -rn |sed ${1}q
None of those Unix commands were designed with that
problem in mind…
Yet they work together beautifully to solve the problem.
So, how does an IT organization get started down this path?
Application Operations
Service Operations
Infrastructure OperationsStart Here
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
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
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
Yay! All my problems are solved!
Not likely…
Seek advice and iterate.
