Clash on the Clouds
By Siddhesh Kabe
What      it?
Cloud Computing, huh
IS
Cloud Computing is Internet-based computing
 
Traditional Approach
Before the Big Bang of Cloud Computing, 
how the stone age world lived and performed.

To build a simple enterprise application 
like HRM, CRM you need to
Buy costly servers

Install workstations and 
connect them to servers
Make a tangable mess of wires
Buy costly software and keep track of licenses

No flexibility 
Get chained to workstations
In Summary: A      mess!!!

WHY???
WHY???
And then 
there was the Big Bang!!
One          Login
Internet Access
A       internet access!!!!
And alll         well!!!
IZZZ
SINGLE
GOOD
Stay Awake
Its a REVOLUTION and its HAPPENING now!!!
6 reasons why Cloud based solutions
Reduced Cost
No more need to spend
on costly hardware

No need to hire large staff to
manage hardware
You pay incrementally, 
whenever you need 
and thus save
Good choice during RECESSION!!!
Increased Storage
Organizations store
data on multiple servers
You can purchase more space
which is 10 times less than
cost to buy your own server
With a good vendor your 
data storage is unlimited
Highly Automated 
Dedicated staff 
managing your servers
Strong and robust 
distributed systems to
protect data
Flexibility
A cloud solution is 
good for small
organization
As well as a large organization
Mobility 
Available on Mobile devices
As well as from anywhere
on the globe with net connection
Who wants to sit on the desk NOWADAYS?
Worry about business 
logic
not hardware
With no worries about hardware,
you can work wonders on logic
You are good in your business, 
let others worry about your IT
A thousand monkeys hitting keys at random on thousand typewriter 
keyboard will almost surely type a given text, such 
as the complete works of William Shakespeare, 
unfortunately this isn't true for INTERNET.
The Cloud Computing Pyramid
SaaS
PaaS
IaaS
Applications on cloud
Many restriction on the services
Predesigned applications
Sometimes free; easy to use; lots of different offerings; easy to access; good consumer adoption; proven business models


You can only use the application as far as what it is designed for; no control or knowledge of underlying technology



Examples:
Software as the service
BIG
ROCK!!!
Platform as a service
Cloud Platforms
The middle layer of the Cloud Computing Pyramid allows developers to build applications to run on the platform provider's infrastructure. This frees the developers from concerns about environment configuration and infrastructure scaling, but offers limited control.
Rich platform to develop applications
Tested infrastructure
API Libraries
Examples:
Infrastructure as a service
Cloud Infrastructure
Full freedom to developers
Freedom from
maintaining servers
Sometimes costly that others
Difficult for 
developers to develop
Examples:
Open Social also a
part of this layer
OMG
Cloud Computing!!!
But then, how     it?
IS
You choose vendors to host your apps
No longer your headache
Cloud Computing rocks!
Inter-cloud
Issues in cloud computing
A presentation on Cloud Computing
Private Cloud
Its your way or no way
Safe and Secure data
Easily Scalable Technology
Easy to use and setup
Most safest technology
Go-live faster than 
making coffee
Data remains with you
Public Cloud
The power of universe at your disposal
You made your point
Whats more in cloud?
Easy and inexpensive set-up 
because hardware, application and bandwidth costs are covered by the provider. 
Scalability to meet needs. 
No wasted resources
Xamples:
Amazon Elastic Compute Cloud (EC2), IBM's Blue Cloud, Sun Cloud, Google AppEngine and Windows Azure  Services Platform. 
Hybrid Cloud
You get the best of both worlds
Scalability and cost-effectiveness
Most Secure
Protected by Firewall
Xamples:
Mix and Match
is an interconnected global "cloud of clouds"
Global Appeal
Only 5 computers theory
Complete automation
Just a theory yet
Not all things are good
Reliability 
Can you let someone else handle your data?
Ownership 
Who owns the data in cloud?
Availability and Performance
Who is accountable for server downtime.
Data Privacy
Ownership of code and data. When the receivers padlock the provider's doors,
 how do you get your data and code back?
