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? Presented by Siddhesh Kabe @: hi5@sidoscope.co.in Web: http://siddheshkabe.co.in Twitter: @sidoscope
