Cloud Computing: Sharad Singh Abhishek Sinha Austin Rodrigues Arun Gupta

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Key features of cloud computing include pay-per-use, virtualization, scalability, reliability, and accessibility. While cloud computing provides benefits such as reduced costs, improved collaboration, and flexibility, concerns remain regarding security, internet dependence, and control over data location and ownership. Overall, cloud computing is an emerging technology that is transforming IT through on-demand services.

What is Cloud Computing?

 “Cloud” is simply a metaphor


for the internet.
 Users do not have or need

knowledge, control, ownership


in the computer infrastructure.
 Users simply rent or access the

software, paying only for what


they use.
History of Cloud Computing
 Concept dating back to the 1960’s by John McCarthy, a
computer scientist, brought up the idea that "computation may
someday be organized as a public utility”

 Idea that revolutionized Cloud Computing: Moving from


clustering computing to grid computing
– Clustering
– Grid

 “In some ways, the cloud is a natural next step from the grid-utility
model,” said Frank Gens, an analyst at the research firm IDC
Early Leaders in the Industry
 In 2007, Microsoft made available free software,
www.live.com that connects its Windows operating system
to software services delivered on the Internet

 Launched in July 2002, Amazon Web Services provided


online services for other web sites or client-side applications

 3tera launched its AppLogic system in February, 2006

 IBM’s system introduced in the mid 2000’s is called Blue


Cloud
Functionality
 Cloud computing is an emerging technology that is revolutionizing IT
infrastructures and flexibility, and software as a service (SaaS)

 During this economic time of recession, there are huge cost-reduction


pressures and cloud computing allows businesses to do just that by
tapping into cloud computing platforms on a pay-as-you-go basis

 Customer retention is vital, especially today in our economy.

 Software and applications are extremely costly. With cloud, you rent
so the heavy investment is forgone

 Cloud computing is a set of technologies and business practices that


enable companies of all sizes to build, deploy, monitor and scale
applications using resources accessed over the internet
What Technologies is Cloud
Computing Replacing
 Cloud computing is replacing large Corporate
Data Centers and unnecessary, expensive
private server infrastructure.

 Web 2.0, SaaS, Enterprise and government


users are adopting cloud computing because it
eliminates capital investment in hardware and
facilities as well as reduces operations labor
COMPANIES LEADING IN
CLOUD COMPUTING
 “Google 101”
– Network made up of millions of cheap servers, that would store staggering
amounts of data;
– Makes search faster, helping us to find out answers to billions of queries in a
fraction of a second.

 Google has invested more than $2 billion a year in data


centers for cloud computing.

 By far the leader in the technology


 Amazon Elastic Compute Cloud “Amazon EC2”
– web service interface that provides resizable computing capacity in a cloud
– designed to make web-scale computing easier for developers
– reduces the time required to obtain and boot new server space from weeks to
minutes
– allows developers to pay only for capacity that they actually use
 “Azure”
– Internet-scale cloud computing and services platform hosted in Microsoft data
centers
– Provides a range of functionality to build applications that span from consumer
web to enterprise scenarios
– Designed to help developers quickly and easily create, deploy, manage, and
distribute web services and applications on the internet.
Scalable Pricing and Cloud Computing

 Models of Pricing
 Free
 Subscription Model
 Pay Per Use
 Perpetual License
What do these Services Offer an
Organization?

 Cloud computing will lead to increase in the


following categories:
– Virtualization
– Usability
– Standardization
– Scalability
Cloud Computing Usage
 Cloud Computing has 3 major uses:
– Infrastructure as a Service
– Platform as a Service
– Software as a Service
Infrastructure as a Service
 Defined as delivery of computer infrastructure as a service
 Fully outsourced service so businesses do not have to purchase servers,
software or equipment

 Infrastructure providers can dynamically allocate resources


for service providers
 Service providers offer this service to end users
 Allows cost savings for the service providers, since they do not need to operate
their own datacenter
 Ad hoc systems allow quick customization to consumer demands
Platform as a Service
 Provides all the facilities necessary to support
the complete process of building and
delivering web applications and services, all
available over the internet.

 Infrastructure providers can transparently alter


the platforms for their customers’ unique
needs.
Software as a Service
 Defined as service-on-demand, where a provider will license
software tailored

 Infrastructure providers can allow customers’ to run


applications off their infrastructure, but transparent to the end
user
 Customers can utilize greater computing power while saving on the
following
– Cost
– Space
– Power Consumption
– Facility
Cloud Computing Pros
 Reduced Hardware equipment for end users
 Improved Performance
 Lower Hardware and Software Maintenance
 Instant Software Updates
 Accessibility
 Less Expensive (Amazon example)
 Better Collaboration
 Pay for what you use
 Flexible
Cloud Computing Cons
 Security Issues (#1 concern)
 Internet connection
 Too many platforms
 Location of Servers
 Time for Transition
 Speed
THE FUTURE OF CLOUD
COMPUTING
Cloud is in the Infancy Stage
 Many companies are only using cloud
computing for small projects.

 The trust hasn’t been accepted

 Details such as licensing, privacy, security,


compliance and network monitoring need to
be finalized for the trust to be realized
Future Educational Uses
 An expansion of Microsoft live@edu
 More useful spending of technology budgets
 Classroom collaboration
 Office Web Applications
 Google Docs
Future Personal Uses
 No more backing up files to thumb drives or
syncing computers together

 Services replace devices

 A single hard drive for the rest of a person’s


life, accessible anywhere with internet
Expansion
 Resources are expected to triple by 2012, from
$16 billion to $42 billion

 Cloud computing is said to be the foundation


of the next 20 years of IT technology
Recommendations
 Too early for large companies to migrate
 Migrate after adequate development time

 Good investment for small businesses

 Personal use will become more prevalent


THANK YOU
ISSUES????
 Is cloud computing a boon or a bane for the
industry?? ( Hardware, CDCs, ERP vendors, etc. )

 What would be the impact of security breach??

 Who owns the data???

 How much downtime can a business handle??
