Surf Shoppe has recently installed a centralized server for their research and development needs and due to cost requirements they have decided to go with a single centralized server for all of their data sharing needs. There are many reasons for going with a single centralized server system over a multi-server system; the most prominent reason would be cost. Servers and network designing can be quite the expensive endeavor and must be maintained on a daily basis in order to keep everything in top running order. The total equipment cost can be managed by properly planning what will be required to maintain this system. This server will be required to run application, print and file sharing services. Of these services the application service will be the most strenuous on the system due to the fact that it will be constantly sending and receiving data through the applications SQL services to maintain the company’s database. A benefit to having only one server running an application is that it drastically cuts down on the amount of issues with maintaining data integrity and replication between multiple systems. Also only having one active database full of information will help keep records current by not allowing two users to access and modify the same file at the same time. You can run into this being a problem if you have multiple servers with redundant information. It is very common for two servers to loose connectivity between each other and cause issues with replication. Surf Shoppe has approximately 25 employees that will need access to the networks shared folders and applications at any given time. A single server will be able to handle the current work load as long as it has been configured properly.

Server-based networks are higher in cost because money is invested for dedicated servers, network operating software, and network administrators with technical expertise required for network management and configuration. On a small network consisting of fewer than five workstations, client/server architecture is not recommended and is very costly.

This case study is an analysis of the Chicago Tribunes Server consolidation in which the Chicago Tribune moved its critical applications from several mainframes and older Sun servers to new, dual-site data-center infrastructure based on Sun 15K servers. The Tribune clustered the Sun servers over a 2-mile distance, lighting up a dark-fiber, 1-Gbps link between two data centers. This configuration let the newspaper spread the processing load between the servers while improving redundancy and options for disaster recovery. (Baltzan and Philips, 2009 p 162)

The most common uses of these types of systems are commercial servers of web applications such used in on line commerce. The advantages of this particular configuration are that they can be easily upgraded by the addition of more processors. These processors are available to execute any of the given processes as soon as the operating system recognizes and configures the new hardware. However, the limitations of such a configuration are that with shared memory, there is a strong emphasis on data manipulation. As each processor competes for a limited amount of shared memory, this limits the speed and up-gradability of such a system. Manufacturers must rely on the development of faster, higher capacity memory to overcome this disadvantage. Currently symmetric multiprocessing computers can address up to 14 gigabytes of physical memory and approximately 2 terabytes of storage. (Sequent Manufacturing Inc., white papers 1998)
The goal of a distributed system is for the user to experience their interaction with the system as if it was a single system. However, it can be advantageous to disclose to the user that they are using a distributed system. For example, a user may be more forgiving for latency in a program if they understand the information must travel a long distance over the network to be processed and then return with the requested solution. This idea is called transparency, the revealing to the user some of the inner workings of the system. Openness was mentioned as an advantage of distributed systems which is true in the context of universally used internet protocols. Many applications and higher level programs have specific interoperability that does not allow for ease of communication between components. Another attribute also listed in the advantages of distributed systems that contains polarity in that context is the systems scalability. While the ability to increase a systems ability to meet demands is positive the carrying out of that task can be in creditably costly, complex, and difficult. If the system needs more processing power it may be conceptually easy to purchase more servers or rent more instances from a provider yet these actions can be extremely costly. Next is the issue of security. With distributed systems many of the different elements of the system are managed by different companies. This lack of continuity means security measures may be weaker in a particular component of the system but with a difficult task of providing proof since lack of access to the differently owned component. The transmission of information also most likely takes place over the open internet. This leaves the data exposed to security threats during entry, exit, and on its journey through the network. The quality of service able to be

Malware protection is another factor to appreciate, as this vice can lead to significant losses to an organization as it corrupts available data for use. The various networks that are used by business firms should consider adhering to network design principles that uphold the security standards set in place. The organizational staff using the different accounts of the company should be limited, and very few individuals should only access the administrator database. Moreover, the various user activities should be regularly monitored and consider changing of account passwords or deleting none existing accounts (Wolden et al., 2015).
Business strategy and model: Zappos.com had a differentiation strategy with which they had differentiated themselves from the rest of the market. They had use a unique corporate culture in their company which was one of the major competitive edges of the company. According to the CEO of the company, Tony Hsieh, that everything that they had done at Zappos such as their relationships with 1,200 to 1,500 brands, policies and website style could be copied, however, the only thing that no one could copy from them was their unique culture. Zappos had 10 unique core values as a basis of their company’s culture, employee performance and their overall operations. They were hiring and firing people on the basis of their abilities that whether they were living up to these core values or not.
Virtualization, which is when one computer hosts the appearance of many computers will be necessary for my future. Virtualization will be needed to access the company’s database to confirm client’s flight reservations, purchase orders, etc. We would also need it to have flight simulators for new parts at the manufacturing company. For example, we would need to have a flight simulator that will give us all the information a real computer would and that would respond to our commands, to test the plane without having to put the actual expensive software and hardware in the plane. The second concept that can be applied to my dream job is database management system. I would need this concept to be able to have an extensive amount of data that is accurate, to control redundancy, and to have a safe backup/recovery process. As an executive officer, I need to be able to rely on database management system to give me accurate information on parts that have caused flights to take emergency landings for example. This could include all the materials used in the production of the product or vendor information. Finally, the WAN concept is essential for my dream job because I need to be able to have computers that connect between two or more different sites. For a manufacturing company, there would be multiple sites where items
IT systems are imperative in present organizations and it is not mandatory to invest in sophisticate technologies. Small systems can also be used to manage internal information within areas. Local structured databases such as MS Access and common files in the shared server can play a crucial role in the organization processes.
