Abstract:
In current IT/ITES market where most of the organization started to implement the “Integration
of Service based Methodology” for their clients and also for the internal structure of organization
(especially for the dedicated IS team of the organization).The “Cloud Concept” built upon
the three pillars of current computing system such as “Infrastructure”, ”Platform” and
the “Software” or applications. The business benefit of “Cloud” is it use to provide “On demand
Service” which helps to full fill the demand of chain execution can be the cause of reducing
expenses of implementation of multiple processing units. Cloud provides the concept of
updating of resources without affecting the underlying infrastructure, which reduce the need
of backup system and encourage the continuous execution of application. Cloud provides
potential “Reliability” and “Scalability” for the applications either deployed or are running on
cloud. Since, cloud use to assure out most security for any business application, it provides
a “Private Cluster” for each application.
Since in IT/ITES service industries, the cost of “Data Security”, “Server
Management” ,”Application Management”, “Infrastructure Management” and “Services
Software” etc are increasing day by day. A report from “Data Centre India” reviled that the
above expenses in 2012 will be around 296 dollar per day where as in 2011, 2010, 2009,2008 it
was 280 dollars, 260 dollars, 244 dollars and 211 dollars.
Why Cloud- As basic Business Scenarios:
Suppose, a business unit of an enterprise requires to deploy an application which will do the
critical “Business Analysis considering some factors of current Market”. This application need
to be deployed wit in a week time but to deploy this using the resource of organization will
take a lots of time because to follow some of the cyclic processes. In this scenarios the “Cloud
Computing” mainly the part called “Infrastructure as a Service” is very useful to make the things
done with minimal expenses. This not only reduce the cost of deployment, but also reduce
the timeframe to task done, platform independent, security, scalability, ongoing enhancement
facilities etc. In one word “Cloud” opened multiple way for upcoming business facilities. A
research shows by implementing “Cloud based Solution or deployment” approaches” the 73%
of company able to reach their “Time of Market(TOM)” for particular application and “Total
Cost Ownership(TCO)” of services was showing low rate then “On-Premise” services with a
fair “Return on Investment(ROI)”.
What is Cloud?
Application platform, consumer service, infrastructure provided by the service provider to build
internet application. The service provided by cloud are categorize in i) Software As a Service
ii) Infrastructure As a Service iii) Platform As a Service iv) Database As a Service v) Software
plus Service etc. Cloud service platform are in infancy but this yet not measure by any business
model or metric. Some service provider such as Microsoft, Amazon, Oracle has added the
credibility for future use.
Cloud Architecture:
Cloud architecture are based on creation of large datacenter by defining a n abstraction
between the platform and the operational system. Basically systems which use for deploying
an application or information storing are used to call “Management Fabric Automated” system.
This also an important part of cloud architecture. At the time of the deployment it provisions
the hardware, deploy the operating system image on server and deploy services on server.
The number of server can be more than one. The set of server can also follow the “Grid
Approach”, i.e. can be connected through LAN. The owner of the service can set the “Security
Configuration” and other “Access Right” for service. Instead of that the architecture also use to
have “Load Balance”, “DNS Server” and “”.”Switches” and “Router”.
