“The Cloud”

thus...


Confused ?


“The interesting thing about cloud

computing is that we’ve redefined

cloud computing to include

everything that we already do…

The computer industry is the only

industry that is more fashion-

driven than women’s fashion…”

-- Larry Ellison

Larry’s World

-> This doesn’t help!


…be honest !!


Let’s talk about it


Reason #1 : Why the confusion ?

Once upon a time…


Remember when ….

The Cloud =

The Internet


IT Professional Slang…

“It’s up on the Cloud”

“It’s in the Cloud”

“Put it in the Cloud”


“Definitions” have

Multiple

Scopes/Contexts

“Points of View”



Not a Programmer ?

What is The Cloud ?

Slide 26…


Cloud Computing refers to both the

applications delivered as services over

the Internet and the hardware and

systems software in the datacenters

that provide those services. The

services themselves have long been

referred to as Software as a Service

(SaaS).

The datacenter hardware and software

is what we will call a Cloud. When a

Cloud is made available in a pay-as-

you-go manner to the general public,

we call it a Public Cloud.

hint: Don’t worry about

the definition so

much

as understanding

THE IMPACT


We are not in Kansas

anymore ?


Inflection Point… Paradigm Shift… Disruptive Tech…


Why it

Matters?


$$$ Always / Yes…

but not always directly about price

per Unit.

Speed & Flexibility


I thought this was about

Computers… ?


Flexibility = Amount of

Compute/Storage Capacity

Speed = Time to Provision

Compute/Storage Capacity


What’s with the

light bulbs ?

It’s a good analogy / Thought Experiment…


What if…

It took time (say minutes to hours to

days) to get electricity from the time

you turned it on (flipped the switch).

What would be different ?


What if…

I also had to request electricity in

different amounts for 1 light bulb vs.

20 or to run 3 machines vs. 100.




I would need to

really, really understand:


When do I really need it? Planning

How long will it take to get it?

Where do I it get it from ?

I’ll probably ask for it before I really

need it to make sure I get it in time…

I will probably ask for more then I need to ensure I have enough…


Complicated ?


Very

Yes this is called:

Supply Chain Management


But Wait…


Electricity is a Utility

On-Demand (Speed = Instant) Flexible (Unlimited Capacity sort of)

Cost = Consumption


Yes…

“The Cloud”

is a Service called

Utility Computing

aka: IaaS - Infrastructure as a Service


“The Cloud”

provides Compute / Storage

/ Network resources that

are:


“The Cloud”

On Demand (near instant)

Pay Per Consumption

Infinite Capacity (illusion of)


OK

I understand

that...

Why is that a big deal ?


Traditional Model

Vs.

Cloud Model

Computing Infrastructure


Traditional Model

Computing Infrastructure


Buy Capacity

Computers/Servers

Storage-Memory/Disk

Network/Bandwidth


Wait…..

Shipped Received,

Unboxed, Installed…


Wait…..

I need a place to put them: build/rent Datacenter

Hire people to maintain… replace eventually…


Wait… CIO Says…

Since I am buying X amount I want to make sure that is not to too

much or too little.

And use as much as possible e.g. near 100% Utilization


Supply/Demand for

Compute


In this world…..

Wasted Capacity /

Low Utilization =

Wasted $$$


Traditionally Capital

Intensive

Not Fast…

Not Flexible…


Cloud Model


Cloud….. Capacity = Demand

(more closely)

CapEx OpEx


"My people come and go so quickly here"

“It’s good if Servers do too"


Provision

/De-Provision

to match demand… usually takes Minutes….


Pay for what you

Use

Consumption Pricing


Black White


Cloud Zealot ?

No it’s not black

and white !


$$$ Reminder…


Cloud is Usually faster, usually

faster is better but maybe not

that important.

Cloud is not always cheaper

especially for fixed

demand/capacity workloads


Capital Expenses I can

Depreciate

Not all apps are created equal

Mission Critical vs.

Productivity applications

Regulations, Privacy, Security


Public Cloud

We have been talking thus far

about the

Public Cloud


On-Demand Pay Per Consumption

Infinite Capacity


Private Cloud?

What’s the deal with that ?


Private Cloud? You own the Hardware:

No infinite Capacity

No Pay Per Consumption

Mostly about speed of and

managing Provisioning

(aka utilization of Capacity)


Hybrid Cloud?

What’s the deal with that ?


Private Cloud

Public Cloud

Using Private and Some Public… often referred to as Cloud Bursting (to gain additional capacity)


Many Believe: ~>me too!

Large enterprise will more than likely be consumers of Public, Private and Hybrid Cloud Models for many years to come.


Wait a minute…


Aren’t these the “Cloud” too?


Sort of but not really…

They are considered Platform as a

Service (PaaS) offerings and run

on Public Clouds or private Cloud

“like” Infrastructures.


Let’s talk about it

IaaS Provides on-demand core infrastructure that can be configured to be anything..


PaaS – Platform as a Service

Application Platform Centric

Abstracts hardware from Developers

CloudFoundry

Heroku Appfog

Can be built on IaaS

The Cloud


Core Infrastructure can now be

Codified


Infrastructure = Code

Infrastructure = Software


Say What ?

My hardware is now software ?


Yes Your infrastructure can now

be created with only software.


Huge

Infrastructure = Code How ?
