Introduction

UNIX, the ancestor of LINUX was a command line operating system that supported only textual commands to operate computer systems. In spite of these limitations UNIX is still considered as the most popular operating system due to its distribution and support base as well as due to its reliable architecture. Linus Torvalds, the inventor of Linux, made a cloned version of UNIX and called it LINUX. The initial version of LINUX was very minimal with a LINUX Kernal and the command line interface “bash”, update utility for flushing the file streams and GCC a compiler. Linus published his operating system on the internet ...

Primary Advantages of GUI over CLI in Linux System Administration

The Graphical User Interface (GUI) is typically easier to use than the Command Line Interface (CLI). Primarily because the GUI requires less training and experience, a GUI user can conveniently click around the applications to find whatever is needed, on the other hand the a CLI requires the user to have knowledge of different kinds of arcane commands which the average user lacks. GUI makes it easier to multitask as compared to the CLI since users can utilize windows to manipulate, toggle and control a multiple applications and files at the same time. New users can also quickly pick up a graphical interface ...

Describe the hardware, software and network architectural design of the infrastructure used to build cloud computing infrastructures.

Cloud computing is a computing model that depends on sharing computing resources as opposed to having local servers handling applications. Cloud computing involves delivering services that have been hosted over the internet. Such services can be classified into three main categories: - Platform-as-a-Service (PaaS) - Software-as-a-Service (SaaS) - Infrastructure-as-a-Service (IaaS) The following is the architectural design of a cloud computing infrastructure. It involves software and hardware designed by a particular cloud architect. Cloud computing involves a large number of cloud components communicating with each other over various application programming interfaces (APIs), usually as web services. The cloud computing architectural ...

Introduction

This is a technology that allows the separation of personal computer desktop environment from the seen physical machine. The technology involved for the realization of such success is the client-server technology. In this scenario, applications are run o the server whereas the user can access the same as if available on the local desktop. The resulting virtualized desktop environment is stored on the remote central server designated for the purpose. This is in opposite to what is normally done, that is the storage of applications on remote clients. The resulting realization is that, when a user works on their local machine, ...
