1. Introduction1.1. What is Cloud Computing?

Cloud computing may be be defined as the collaboration of computing resources in acommon place via a computer network. The term Cloud represents a GRID of Computers that effectively function together to supply data a nd software as required.Cloud Technology has a number of benefits, including significant reduction of InfrastructureCosts, Reduction of Carbon Footprints, and reduction of Administration Overheads etc alongwith a substantial increase in flexibility and reliability.

Cloud provisions appropriate resources, as demanded by the system, from a common poolof elastic shared resources that are made available instantly, as required. With Internetsreach spreading rapidly, the need to purchase expensive hardware and computing systemsfor running ones applications is slowly but surely becoming redundant, as a high amount of resources are needed only when the number of applications running are more in numberthan the usual. Such a scenario calls for a more cost effective solution, which is readilyprovided by Cloud Technology.

Running a website from home is a difficult task, since it requires continuous monitoring of resources to performance ratio of the server on which the website is hosted and other

factors to ensure that the website is running smoothly. But Cloud Technology simplifies theprocess by providing ample resources to ensure top-notch performance for your website,thus eliminating the need for frequent monitoring and taking care of all your worries.

It will show Disk /dev/xvde doesnt contain a valid partition table which mean theserver has detected the additional disk.

3) Now initialize the PhysicalVolume using command pvcreate [root@centos ~]# pvcreate /dev/xvde

4) Add the above initialized PhysicalVolume to existing group with vgextend [root@centos ~]# vgextend VolGroup00 /dev/xvde

6) Final step, without which Linux will not detect the extended partition or space. Usecommand resize2fs which will resize the file system and update kernel with extended

space of logical volume.[root@centos ~]# resize2fs /dev/mapper/VolGroup00-LogVol00
