What type of architecture should the new payroll application use and why. The new payroll system will utilize a client/server based architecture with the use of thin clients running from a central terminal server located at the Data Center. The terminal server will communicate with the application server where the new payroll application will reside, and the application server will communicate with the payroll database server. The decision to use thin clients versus a traditional PC is based on cost, security, and network traffic. According to 2X Software, a study conducted by Bloor Research shows that “Implementing thin client technology in businesses can reduce costs by up to 70%.” (2X Cloud Computing Software, 2010) There are also cost savings in the software since it will run on a server environment, there will be no cost per installation. From a security perspective, information and data security can be improved with the use of thin clients. Since they don't have local disks or portable media drives, they are less vulnerable to antivirus and spyware. Users can only store data on remote file servers and cannot copy or move critical data to portable media. Using thin clients in a domain on the network makes system administration easier and more secure than controlling remote users and controlling system policies in the domain which reduces internal threats to the system. (Caghan Cimen, April 2014) Regarding network traffic, the traffic used by a thin client is significantly lower than that of a PC since the workspace is on a centralized server and traffic to the terminal is strictly inbound and outgoing. Most of the data traffic occurs from server to server, as in this case from the terminal server to...... means of paper ...... clues of ethics and professional conduct, which can act as a guideline for individuals and other organizations.
