Introduction

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.

Cloud Architecture

Individual users connect to the cloud

from their own personal computers

or portable devices, over the

Internet. To these individual users,

the cloud is seen as a single

application, device, or document.

The hardware in the cloud (and the

operating system that manages the

hardware connections) is invisible.

Characteristics of Cloud Computing

Cloud Service Models

Cloud Service Models

• 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.

Models of Clouds

Modes of Cloud

Public Cloud• Computing infrastructure is hosted by cloud vendor at the vendors

premises.• And can be shared by various organizations.• E.g. : Amazon, Google, Microsoft, Sales force

Private Cloud• The computing infrastructure is dedicated to a particular organization

and not shared with other organizations.• More expensive and more secure when compare to public cloud.• E.g. : HP data center, IBM, Sun, Oracle, 3tera

Hybrid Cloud • Organizations may host critical applications on private clouds.• Where as relatively less security concerns on public cloud.• Usage of both public and private together is called hybrid cloud.

Advantages of Cloud Computing

• Lower Computing Cost

• Improved Performance

• Reduced Software Cost

• Instant Software Updates

• Unlimited Storage Capacity

• Increased Data Reliability

• Device Independence and the “always on!,

anywhere and any place”

• Free From Maintenance and the “no-need-to-

know”

Disadvantages of Cloud Computing

• Security Issues

• Features might be limited

• Privacy Policies

• Does not work well with low-speed

connections

• Cannot access without network
