Before you begin this assignment, be sure you:
Have completed all previously assigned readings.
Read the 3D Printing Case Study.”
Reviewed the feedback on your 3D Printing Stage 1, 2 and 3 Assignments.
It is now a year later, and Mark has opened his two new facilities in Memphis, Tennessee and Phoenix,
Arizona. All three locations are operating almost around the clock to create 3D printed accessibility and
assistive devices. Mark and his father are planning to open several more facilities, also located near
Veterans Administration Hospitals and rehab facilities.
Mark does not want to continue to increase his IT infrastructure at the original location and has decided
to move all of his systems and files to a cloud service provider. You have recommended that since he
has everything set up the way he wants it and the systems are performing well for him, that he just
move what he has to an Infrastructure as a Service (IaaS) cloud provider. Before Mark agrees to this, he
wants to understand more about just how that would work, using his current systems and locations. He
also has a lot of questions about how the communications systems work, and he wants to understand
the protocols, the architecture and the four layer TCP model.
Use the following outline for your paper:
1. Provide an opening paragraph as an introduction that explains what is contained in the paper.
(You might write this after you develop the rest of your paper.)
2. Explain what IT infrastructure changes will occur at the original location by telling Mark which
components will be located at the IaaS cloud provider’s location and what will remain at his
facility. Explain any changes that are needed at the two remote locations in order to use the
IaaS cloud services. Provide a list of which components will be located at the cloud location, at
Mark’s primary facility, and at the two remote locations.
3. Create an original graphical representation showing the cloud provider and the three current
locations. Show which components will be located at the cloud provider’s site and which will
remain at the three locations. Label each component and the locations.
4. List the protocol involved for each communication link in the design, including internet
connectivity, wired connections, and wireless connections. Be sure to include security
protocols, as appropriate to the infrastructure design you created and the components you
identified.
5. Explain the concept of a layered systems architecture to aid in communications and the benefit
of a layered architecture such as the TCP or OSI model.
6. Using the four layer TCP model, explain what each layer’s function is and how it will apply when
Mark uses his ERP information system that will be located at the cloud service provider’s
location.
7. Using the four layer TCP model, explain what happens when a packet of information travels
from the server at the cloud provider to a tablet device at Mark’s facility. Be sure to identify the
points at which each of the layers of the model are the primary enabler of the communication.

3D Printing Case Study
In late 2015, Mark Peterson acquired a 3D printer from Best Buy for $500. As he began to play around
with it, he discovered that he could use designs he downloaded from the Internet to create a wide
variety of objects. One day as he was exploring designs on the website MyMiniFactory.com
(https://www.myminifactory.com/), he came across a category of accessibility items. He was very
excited to discover such things as an umbrella holder for a wheelchair, because his brother Peter uses a
wheelchair for mobility. He downloaded the umbrella holder design and made one for Peter. The first
time Peter used the umbrella holder, several people came up and asked him where he had gotten it. Of
course, he was proud to say his brother had made it, but he had no idea how much it would cost for
Mark to make one for a customer. Peter took the names and phone numbers of two people he
encountered and promised to get back to them. When Peter approached Mark with the requests, Mark
knew that he had found the start of something good. He figured out what the time and material cost
would be to make the holders, called the interested parties, and made his first two sales.
As he continued exploring, Mark ran across an article describing ten 3D printable assistive and
accessibility devices (https://3dprint.com/126214/103dp-devices-for-the-disabled/). After investing in a
heavy duty 3D printer, Mark used his Facebook page to advertise his growing business in 3D printing
assistive and accessibility devices. He soon had many orders and his 3D printing hobby became his
fulltime occupation.
Mark rented space in an industrial park, bought two more wireless 3D printers, and hired two part-time
assistants. He brought his PC from home to control the 3D printers, and set up an Internet connection
using Verizon FiOS. His PC is connected to a FiOS modem which has a built-in wireless router. Mark
obtains his 3D printing designs from sources on the internet. He uses Google email and keeps track of
his orders on a spreadsheet on his PC.
Mark's Expansion Plan: Now, just three months later, he is ready to add seven more 3D printers and a
3D scanner, and hire five fulltime employees. Before he grows that much, he needs to set up his IT
infrastructure to manage not only the additional 3D printers, but also to manage his business. He wants
to implement a small business enterprise resource management (ERP) information system in his facility
to help him manage his business (customer orders, invoices, supply ordering, employees, etc.) more
effectively. He realizes he will also need a document printer to print invoices, etc. In addition, he wants
each of his employees to have mobile access to the ERP system and the 3D design files and printers from
anywhere in the facility, and he wants as much flexibility in which computers control which 3D printers
as possible. He has a large collection of 3D print design files and has downloaded some training videos
that he will use to train his new employees. Mark has already decided that he wants to store all of his
3D production files and his business management information locally in his facility, and to use cloud
storage for his backup files.
Your assignment, which will be done in four stages, is to assist Mark in understanding what kind of
infrastructure he needs; how it would be configured; how it will change when his business grows into a
much larger, multi-location operation; and how the various devices communicate with each other.
Specific instructions for each of the four staged assignments may be found under the Assignments tab.

Background
In 2015, Mark bought a 3 printer worth of $500 from Best Buy. While Mark used the
printer, he discovered a wide range of features that he could use to create various objects such as
wheelchair umbrella holder. Mark's business focuses on designing and printing devices for the
physically challenged people. Mark established his business in an industrial park and added two
more 3D printers to support his operations. He also recruited two part-time workers to assist in
the daily running of the business. Mark is currently looking to expand his enterprise by adding
more printers and employees. Besides, he wants to implement an enterprise resource planning
system (ERP) for a small business to assist him to manage his enterprise. ERP system will enable
Mark to effectively manage daily business operations such as customer orders, employees,
invoices, and supply orders among others. The business requires an ERP to boost accessibility
and flexibility where all employees can access printers and design files from anywhere within the
premises. For Mark to attain his business goals and improve processes, he needs to configure his
information technology to support the future expansion of the business.

Requirements
The following system requirements need to be met to support Mark's business expansion:
1. Enterprise Resource Planning (ERP). It will enable Mark to effectively manage daily
business operations such as the supply inventory, billing, and customer requests among
others.
2. Wide Network administration for all 3D printers on the network.
3. Document Printing solutions to enable printing pay stubs and client invoices.
4. Network Attached Storage for backup of crucial business information.
5. Mobile access option for the ERP to ensure flexible file sharing and storage.
How the requirements will be met?
The following system components will be required to meet each of the five requirements above.
1. Network server: It runs an operating system intended to support multiple users in a
network. It enables the effective running of applications such as print servers, email,
messaging, databases, and ERP among others.
2. Wireless Access Point (WAP): This will enable all employees to have access to the local
area network. WAP will enable wireless connection thereby increasing mobility,
responsiveness, flexibility, and support for future business expansion.
3. Multifunctional Printer (MFP): This will allow employees to perform operations such as
printing, faxing, copying, and scanning using a single device (Balletti, Ballarin & Guerra,
2017). It will also allow employees to print large quantities in one setting and print from
their mobile devices as well as enhancing digital security for the enterprise.
4. Network Attached Storage: It will enable the storage of files to the network-wide file
server. Essential business information such as 3D designs, customer and employee
information, training materials, and other vital business files will be stored in NAS
(Comer, 2018). It also ensures easy access to data all employees in the firm. Data stored
in NAS can be accessed remotely using remote desktop connection thus providing
flexibility and accessibility.
5. Print Server: This enables the effective management of print jobs, prioritization, and
spooling. It will also offer a dedicated system administrator to manage all printers and
ensure they are online all the time.

Data representation and storage.
1. Digital Data and Numerical Data: This data will be represented in binary codes i.e. 0 and
1. Digital and numerical data are represented as binary digits or bits of 0 and 1. Once the
data is converted into bits and then into bytes, the data forms a digital file that can be
stored on a medium such as DVD, CD, flash drive, and hard disk.
2. Audio data: This data is represented in the form of pieces referred to as samples. Audio
data is captured through an input device such as a microphone. The samples are exported
into storage at a given rate per second. Playing these samples in the same order they were
created generates the original audio file Cherian & Sra, 2016). Audio files are represented
in a digital container format to ensure their storage on a computer system. Audio data are
represented in MP3, WMA, or WVA formats. Audio data is stored in CD, DVD, Flash
drives, and Hard disks.
3. Video data: It is recorded in the form of frames. The frames of still images are recorded
many times per second. The frames create a video when they are played simultaneously.
The frames are compressed and stored in video formats such as AVI, MP4, WMV, or
FLV (Cherian & Sra, 2016). Video data can be stored on Blu-ray, CD, DVD, external or
internal hard drives.
4. Graphics Data: The data is represented and stored in a bitmap image file. The image
contains pixels and elements arranged in a grid p...
