4. What is Cloud Computing?
“Cloud computing is a style of computing where
massively scalable IT-related capabilities are
provided as a service across the Internet to multiple
external customers”
“Cloud computing: A pool of abstracted, highly
scalable, and managed infrastructure capable of
hosting end-customer applications and billed by
consumption”
“Cloud computing is Web-based processing,
whereby shared resources, software, and
information are provided to computers and other
devices (such as smartphones) on demand over
the Internet.”

23. Cloud Service models - Definitions
• SaaS is a software delivery methodology that provides
licensed multi-tenant access to software and its
functions remotely as a Web-based service.
Software as a
Service (SaaS)
• PaaS provides all of the facilities required to support
the complete life cycle of building and delivering web
applications and services entirely from the Internet.
Platform as a
Service (PaaS)
• IaaS is the delivery of technology infrastructure as an
on demand scalable service.
Infrastructure as
a Service (IaaS)
24. Cloud Service models - Characteristics
• Scalable; Multi-tenant; Metadata driven
configurability
• Sometimes free; easy to use; good consumer
adoption; proven business models
Software as a
Service (SaaS)
• Highly scalable; multi-tier architecture; Multi tenant
environments
• Developers can upload a configured applications and it
“runs” within the platform’s framework
Platform as a
Service (PaaS)
• Offers full control of a company’s infrastructure; not
confined to applications or restrictive instances
• Sometimes comes with a price premium; can be
complex to build, manage and maintain

31. Public Cloud
• Owned and managed by service provider
• Made available to the general public or a large industry group
32. Private Cloud
• Operated solely for an organization
• May be managed by the organization or a third party
• Limits access to enterprise and partner network
• Retains high degree of control, privacy and security
33. Community Cloud
• shared infrastructure by several organizations which have
shared concerns
• May be managed by the organizations or a third party
• Costs are spread over fewer users than a public cloud but
more than a single tenant
34. Hybrid Cloud
• Composition of two or more clouds (private, community, or
public) bound together by standardized or proprietary
technology that enables data and application portability
36. Conclusion
Cloud Computing is the fastest growing
part of network based computing . It Provides
tremendous benefits to customers of all sizes:
simple users, developers, enterprises and all
types of organizations.
1960 :- Supercomputers and Mainframe (massive computing was done through utility of supercomputers. The problem with this set-up arises from the cost needed to create a supercomputer or mainframe to the cost of maintaining it in optimal condition. As a result, leading to the idea of an “intergalactic computer network” by J.C.R. Licklider, who was responsible for enabling the development of ARPANET (Advanced Research Projects Agency Network) in 1969. His vision was for everyone on the globe to be interconnected and accessing programs and data at any site, from anywhere.
Afterwards, John McCarthy who proposed the idea of computation being delivered as a public utility, similar to the service bureaus.
1990 :- The first milestones for cloud computing (The arrival of Salesforce.com, which pioneered the concept of delivering enterprise applications via a simple website.
July 2002 :- Launch of Amazon web services (making information available through a web service focused as a retailer, provided a suite of cloud-based services including storage, computation and human intelligence.
March 2006 and August 2006 :- S3 and EC2 (Elastic Compute Cloud)
- infrastructure-as-a-service provider
- making core computing infrastructure service (Cloud infrastructure)
- pricing model ‘pay-per-use’
- shift of Amazon from being just a retailer to a strong player in the technology space
- EC2 as a commercial web service that allows small companies and individuals to rent computers on which to run their own computer applications.
April 2008 :- Launch of Google App Engine
- first pure play technology company into the cloud computing market (browser-based enterprise applications)
- a developer tool enables you to run your web applications on Google’s infrastructure.
- Google App’s features
- Dynamic web serving, persistent storage, automatic scaling and load balancing, Google API’s for authentication users and sending email
November 2009 :- Launch of Windows Azure Beta belonged to Microsoft (the same concept as Google App)
2010 :- Concerns about the security of their corporate data in the cloud. Security, data privacy, network performance are likely to lead to a mix of cloud computing centers both within company firewall and outside of it.
Learn how to secure, manage and monitor the growing range of external resources residing in the cloud including the improvement of faster processors and connections.

Cloud Software as a Service (SaaS). The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure and accessible from various client devices through a thin client interface such as a Web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure, network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Cloud Platform as a Service (PaaS). The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created applications using programming languages and tools supported by the provider (e.g., java, python, .Net). The consumer does not manage or control the underlying cloud infrastructure, network, servers, operating systems, or storage, but the consumer has control over the deployed applications and possibly application hosting environment configurations.
Cloud Infrastructure as a Service (IaaS). The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly select networking components (e.g., firewalls, load balancers).
