What is cloud computing?

Is this cloud computing?


What they are saying?

“Biggest Paradigm Shift in 20 years”

“Game Changers”

“Tremendous Cost Cutting”

“Pay As You Go”

“SaaS” “PaaS”

“IaaS”


Who Cares ?

Whats in it for me?


Real time example?

You can either

Build a house or

Rent an apartment

Say you just moved to a new city

And looking for a home to live


If you Build?

Important decision you have to make

Initial investment, how big or small

Maintenance cost,

Government tax,

Plumber,

Electrician...


If you Rent?

You make a simpler decision

High quality infrastructure

Just pay your rent

and utilities

Pay as you go


Back to cloud computing

Let’s translate to

Cloud Computing?


Building enterprise software

is like….

Building Bungalow

in middle of City

Need to Hire an Army of IT Engineers

Software Upgrade Support

Backup/Restore Service Pack

Development Network issues


What about changes

In the mean time many

thing changes

Economy upside down

Bankruptcy

Can we bridge these Gaps

Time to market

Layoffs


New way of thinking

Cloud Computing is not

the answer

for all

But it definitely simplifies our lives


Deployment model

“public cloud”

“private cloud”

“hybrid cloud”


Public cloud

it is like renting an

apartment

Resources are available to generic public

Accessible only via

internet

No direct connectivity


Private cloud

it is like building an

own house

No internet dependency

Operates for one organization

Security is addressed here

But they have to be build

and managed


Hybrid cloud

building an own house

Secure transaction are

maintained privately

Common operations are open

Renting party halls


Different layers of cloud?

Source: AMR, Gartner, IDC, William Blair & Co

Cloud Infra: Infrastructure on demand - makes pay-by-use feasible. e.g: Amazon EC2, GoGrid, NetMagic

Cloud OS: Defines an auto scaling architecture over IaaS. e.g: Google GAE, Microsoft Azure

Cloud Apps: Application delivered to the end users on a pay-by-use model. e.g: Salesforce.com, SuccessFactors

$9b by 2012 @ 160%

$4b by 2012 @ 60%

$21b by 2012 @ 20%

Cloud Middleware: Simplifies SaaS development, accelerates time to market & ALM eg: OrangeScape, force.com, many others

Service Models


Why IaaS?

giant datacenters

across the globe

Your data is replicated

3 or 4 times in their data center

High Availability

High Traffic, load balance

Network is always up


IaaS

Leave it to the leaders..

Why PaaS?

Programming language

execution environment

Data base

Operating system

Web sever

Auto scaling

Zero hardware and software maintenance


PaaS


Why SaaS?

Access app from

cloud client

Business user/Consumer

Large cloud users - Multitenant

Monthly/yearly flat fee per user

Cloud client – PC, smart phones , tablet, desktop

Here comes the Money


SaaS


Is it really linked to Us?

As an end-consumer, believe it or not

you’ve been using Cloud for long times
