Cloud Computing Concepts and Architectures

This document provides an overview of cloud computing concepts and architectures. It explains the idea of cloud computing as a remotely provisioned and scalable IT environment, and discusses the different service models such as SaaS, PaaS, and IaaS. The implementation steps for cloud computing are also outlined, including defining a project, selecting a platform, and understanding security policies.

Cloud Computing

Concept of Cloud Computing
The concept of cloud can be referred to as an environment that is
basically designed for remotely provision measures and scalable IT
resources. The term of cloud computing originated as a metaphor
relating to the internet which is in essence a network of network
which provides access in a remote manner to a set of decentralised
IT resources. Prior to the concept of cloud emerging as a standard it
was referred to as a symbol which was used to describe the internet
in a variety of mainstream documentation and specification relating
to the web based applications.

Concept of Cloud Computing (Cont.)
Example of the concept of cloud can be Gmail, yahoo mail and
Hotmail etc. the user would be needing just a internet connection
and you can start using the concept of the cloud. The management of
the server and the software are all included into the concept of the
cloud and is well managed by the cloud service provider Google,
Yahoo etc.

Moving to the concept of Cloud
Computing
 The cloud can be implemented using the data centres which act as
a pool of single resources and then the virtual machine should be
started to provision. The concept can be considered to be very
much similar to the aspect of creating a platform of HPC which
directly integrates all the resources which are in the single pool
and then running the virtualised layer.

Cloud Computing Architectures
SaaS (Software as a Service): The concept of Software as a service
can be considered as a business model of software license. The
concept basically involve the support and development of the
software's vendors. Customers can have the concept of paid usage
over the concept of the internet.
PaaS (Platform as a Service): It can be considered as a platform for
the deployment, development, support and testing of the application
which are web based.

Cloud Computing Architectures
(Cont.)
IaaS (Infrastructure as a service): it is a computer infrastructure which is typically in the
form of virtualization and can be considered as a service within the concept of the hosting
of the clouds.

Implementation of the Concept
The steps of implementation of the concept of the cloud computing
are stated below:
 Define the project
 Select the platform of cloud
 Understand the security policies.
