Linux is an open source software that can be downloaded free from the internet and used

by the users. Though the original creator of the software gave it freely, some firms have

redesigned the operating system and sold it for profit. Other software firms have used it to create

their commercial applications such as Oracle. The free availability of Linux has led to its wide

use in mobile phones, enterprise software and consumer electronics. Despite its wide use for

other purposes, only a small fraction has been used in desktop computers. There are various

reasons why this occurs. (Gallaugher, 2012).

First, it is not easy to use Linux. Compared to other operating systems like Mac OS and

Windows, Linux is more complicated to use. Linux is command based. Installation and use of

Linux operating system requires the user to know all the commands for performing each task.

This makes it hard to use. The complexity of Linux can result in total cost of ownership (TOC)

of the computers using Linux.

The small number of people using Linux discourages software industries from creating

software that are supported by the operating system. This means that most applications are not

supported by the operating system discouraging many users. (Gallaugher, 2012).

Some computer users especially in the developing countries prefer Linux. This is because

of their low incomes making it difficult for them to afford expensive commercial operating

systems like Windows and Mac OS. A group of people claim that Linux is more secure

compared to other operating systems thus prefer to use it.

Linux’s market share will increase with time. This is because more firms are redesigning

it and coming up with better and easier to use versions. Software companies like Oracle are also

creating Linux based applications resulting more use of Linux. Increased cybercrime has

demanded the use of Linux which is more secure compared to Windows. (Gallaugher, 2012).

Cloud computing is the modern technology where individuals and firms replace their

computing resources with individual’s or organization’s software or hardware, with internet

provided services. It can be divided into two types; software as a service (SaaS) and utility

computing. (Kling, 2014).

There are some benefits of using cloud computing. The greatest benefit is that the

companies using cloud computing save a lot of money. The forgo the upfront costs incurred

when purchasing and installing software. The software maintenance costs are also reduced

greatly. Less staff are required to run systems and this saves more money. Use of cloud

computing is very flexible. This reduces the risk of making huge capital investments in

information systems. Cloud computing is very scalable. This is important for organizations

which operate in widely varying environments. (Gallaugher, 2012).

Despite the great benefits it has, cloud computing has some challenges. The greatest

challenge is that the organization depends largely on the vendor offering the services. This

means the vendor can easily affect the organization’s performance. It is also not easy to change

from one vendor to another. Using cloud computing means that the organization cannot stick to

old software versions, they must change to any new versions which occur. This results in extra

training costs and users can easily make errors. (Gallaugher, 2012).

A lot of research has been done on cloud computing. Many articles, some true, others

false, have been posted about cloud computing. In the article “Cloud computing is the future but

not if security problems persist”, it does not address the security problem accurately. According

to the author, security is greatly affecting the cloud computing technology. However, adequate

measures have been put to ensure the resources in the cloud are secure. Very few cases of

insecurity have been reported unlike the article explains. (Techtimescom, 2014).

The Defense Travel System was designed to streamline and automate the travel

procedure of the Department of Defense (DoD), support is travel requirements and lower its

related costs. The travelers perform most of the administrative tasks.

For the Defense Travel System to be used, several hardware and software components

must be availed. The server-side must have the following hardware components; a 64-bit

processor, a hard disk space of at least 2 gigabytes, a RAM of at least 2 gigabytes, a monitor with

1024 x 768 resolution and a DVD-ROM drive. The client-side computer should have the

following hardware components; at least 512 megabytes RAM, a hard disk space of at least 500

megabytes and s monitor with 1024 x 768 resolution. The software requirements for the server-

side include; a networking software such as Windows server 2008 and a database software such

as the Oracle Database Patches. The client-side software requirements include; an operating

system such as Windows and a web browser.
