Clouding Computing Introduction

1. CLOUD COMPUTING

2. What is Cloud Computing?
■ Cloud computing enables companies to consume a computer resource,
such as a virtual machine, storage or an application, as a utility (just like
electricity) rather than having to build and maintain computing
infrastructures in house.
■ Cloud computing is a general term for the delivery of hosted services
over the internet.

3. Types of Cloud Computing
Software as a Service (SaaS)
■ Cloud-based applications
run on distant computers “in
the cloud” that are owned
and operated by others and
that connect to users’
computers via the internet
and, usually, a web browser.
■ Auto-updating, Easy access
to app data, no loss of data
are benefits of SaaS.
Platform as a Service (PaaS)
Infrastructure as a Service
(IaaS)
■ PaaS provides a cloud-
based environment with
everything required to
support the complete
lifecycle of building and
delivering web-based
(cloud) applications.
■ Without the cost and
complexity of buying and
managing the underlying
hardware, software etc. is
benefit of PaaS.
■ IaaS provides companies
with computing resources
including servers,
networking, storage, and
data center space on a pay-
per-use basis.
■ No need of buying
Hardware, and pay per use
are the benefits of IaaS.

4. Cloud Computing Deployment Methods
Public Clouds
■ In public clouds, Anyone can access
data or upload data to cloud.
■ They offer rapid access over a public
network to affordable computing
resources.
■ For Example,YouTube, SoundCloud
etc.
Private Clouds
■ In Private Clouds, only Authorized
persons can access data of cloud.
■ For Example, if a company has its
private cloud, then only company
employees can access data
anywhere, anytime. Any third person
would not be allowed to access data.

5. Benefits of Cloud Computing
■ Flexibility
– Users can scale services to fit their needs, customize applications and access cloud
services from anywhere with an internet connection.
■ Efficiency
– Enterprise users can get applications to market quickly, without worrying about
underlying infrastructure costs or maintenance.
■ Secure
– Cloud computing can also guarantee a more secure environment, thanks to
increased resources for security and centralization of data.
