Why Cloud computing ?

IT guys that build computer networks find it easier to draw a Cloud to represent all the connections that make up the Internet

“ Cloud” because……….

Do You Use Cloud ????

Definitions …….

“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 Computing

Cloud refers to hundreds of Internet connections. Your e-mail goes through a “Cloud” of multiple Internet Connections

As Internet grew, IT guys realized that they could do more than just provide connections in the cloud.

Created Big computers with super computing power in the cloud and share these big computers with lots of people.

Cloud Service Models

There are mainly 3 service models given as:

1. Software as a Service (SaaS)

2. Platform as a Service (PaaS)

3. Infrastructure as a Service (IaaS)

Modes of Clouds

Public Cloud / Community CloudComputing 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 CloudThe 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

Low Cost – Capex free . Licenses etc.

Disaster recovery & Backup – avg- 2 hours.

Automatic software updates / Maintenance

Device Independence and the “always on!, anywhere and any place”

Environment friendly. - decreases their carbon footprint.

Disadvantages of Cloud Computing

Security and Privacy in the Cloud. – Hack attacks.

Technical Difficulties and Downtime.

Requires a constant Internet connection.

Does not work well with low-speed connections.
