Problem Scenario:◦ Company “LTET” (Late to Embrace Technology) has

grown substantially in the last few years. ◦ The company manufactures, distributes, and sells

acoustic products. Its manufacturing plants are in China. Its assembly and distribution plants in addition to HQ and sales offices are in the US.

◦ Their current computing environment consists of a few computers scattered here and are not networked.

◦ They rely on paper and do everything manually, but now they are ready to embrace 21st century technologies.

Kaplan University 6

Write a 3 page paper on the following:◦ Propose a network and a computing

environment. ◦ Your plan should identify a client/server class

and a cluster implementation. ◦ Money, time, and resources should NOT be a

consideration in your creative mind.◦ Be sure to give them an efficient and secure

network based on what you learned in this and previous units.

◦ Be sure to defend your recommendations.

Kaplan University 7

Your paper should include at least 3 pages of content (including required content, intro & conclusion)

Note that your paper will be longer than 3 pages as it will have a title page and a reference page in addition to the actual content pages required.

Be to sure include an introduction and conclusion (5 pts each)

Use APA format

A client/server environment includes:◦ Clients – typically single user PCs or workstations

with operating system and easy to use GUI interface

◦ Servers – provides shared services to clients(application server, database server, storage)

◦ Network – how it is all connected to each other


1 Tier◦ Client & Server are same machine

2 Tier◦ Client & Server are separate machines

3-Tier◦ Client (end-user computer)◦ Middle-tier (application server)◦ Back-end server (database server)


Set of standard programming interfaces and protocols that site between the application and the communications software

Has both server and client components


A group of interconnected whole computers working together as a unified computing resource that can create the illusion of being one machine

What are the benefits of this?

Can you name an example of a company that uses a cluster for their infrastructure?


Google


Facebook

Benefits◦ Absolute Scalability

◦ Incremental Scalability

◦ High Availability

◦ Superior price/performance


Used for communication between entities in different systems

◦ Entity – anything capable of sending or receiving(terminal, DBMS, user applications)

◦ System – physically distinct object that contains one or more entities (computers, terminals, remote sensors)

◦ Protocol is the language between the two


7 layer model that identifies protocols for communicating at different layers.

Example Protocols◦ Transmission Control Protocol / Internet Protocol

(TCP/IP)◦ IP – provides routing functionality between

multiple networks◦ TCP – ensures data arrives at the destination

application & the data arrives in the same order it was sent.


Simple Mail Transfer Protocol (SMTP)◦ Provides mechanism for transferring messages

among separate hosts

File Transfer Protocol (FTP)◦ Used to send files from one system to another

under user command

TELNET◦ Provides remote logon capability, which enables a

user at a terminal or PC to logon to a remote computer and function as if directly connected
