How does cloud computing provides on-demand functionality? Cloud computing is a metaphor used for internet. It provides on-demand access to virtualized IT resources that can be shared by others or subscribed by you. It provides an easy way to provide configurable resources by taking it from a shared pool. The pool consists of networks, servers, storage, applications and services. What is the difference between scalability and elasticity? Scalability is a characteristic of cloud computing through which increasing workload can be handled by increasing in proportion the amount of resource capacity. It allows the architecture to provide on demand resources if the requirement is being raised by the traffic. Whereas, elasticity is being one of the characteristic provide the concept of commissioning and decommissioning of large amount of resource capacity dynamically. It is measured by the speed by which the resources are coming on demand and the usage of the resources.

In this post we will see a way to create multiple home directories, remove inherited permissions, remove other users, and then give the user write access to the folder. 1. Create Share for Home Directories On your file server, create a share that will hold all your home directories. Be sure to allow Domain Users to have read access to this share 2. Get a list of all users We wanted the home directories to have the same name as the user's login name. I was able to export a list from Active Directory of all the login names. Save this as a text file with the name file.txt 3. Batch file to create directories Make a batch file with the following lines to create the home directories: @echo off for /f %%i in (file.txt) do mkdir %%i Place this batch file in the root of the share along with the file.txt. Run the batch to create the folders. 4. Removing Inheritance We don't want user's to be able to see the contents of other user's home directories. First we...

file & directory protection is a essential of any OS and Linux OS is no exception for it! These authorizations allow you to choose exactly who can access your files & directory, providing an overall improved system security. There was one of the major flaws in the older Windows operating-system where, by standard, all users can see each other people's information (Windows 95, 98, Me). For overcoming it, editions of the Windows based computer system such as NT, 2000, XP and 2003 lot more security features added. They fully support file & directory permissions, just as Linux system has since the beginning. Together, we'll now assess a directory listing from our Lab Linux system hosting server, to help us understand the information provided. a simple 'ls' command will give you the file and directory listing within a given directory, including the option  '-l' will display number of new areas that we are going to discuss here:
