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.
  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.

Formatting:

  • All parts of the assignment except for the graphic should be about 3-4 single spaced pages in length, and be in Microsoft Word format, or a format that can be read in Word.
  • Part 3 is an original graphic diagram that should be included in the same document.

Introduction

This paper discusses the transition of Mark's 3D printing business to a cloud-based infrastructure using Infrastructure as a Service (IaaS). It will outline the necessary IT infrastructure changes at his original location and remote facilities, illustrate a graphical representation of these changes, enumerate the relevant communication protocols, and explain the layered systems architecture, including the TCP model and how data packets enable communication between his cloud server and devices at his facility.

IT Infrastructure Changes

To facilitate the transition to IaaS, several changes will be necessary at Mark's original facility and remote locations. The existing hardware at the original facility will be assessed to determine which components will migrate to the cloud, thus optimizing physical storage and resources.

At the IaaS cloud provider’s location, Mark will transfer most of his computing resources, including the ERP system, databases for managing orders and inventory, and remote access tools for employees. These components will enable Mark to manage his facilities more efficiently by leveraging the scalable resources of the cloud.

Components remaining at the original facility will include physical 3D printers, local storage for immediate design access, and peripheral devices such as document printers. To ensure optimal functionality, each remote location in Memphis and Phoenix will require reliable connectivity to the cloud services, potentially using WAN links or high-speed internet connections.

Here is a list of the components based on the proposed structure:

  • Cloud Location: ERP System, Database, Backup Storage
  • Mark's Primary Facility: 3D Printers, Local Storage, Document Printer
  • Remote Locations: Production Equipment, Wireless Access Points, Employee Workstations

Graphical Representation

To summarize the changes visually, a diagram will be created that shows the cloud provider and three locations, indicating which components are accessible via the cloud and which remain onsite. Each component will be clearly labeled to provide a comprehensive overview of the new infrastructure setup.

Communication Protocols

The design of Mark’s cloud-based infrastructure utilizes various protocols for seamless communication among devices and to secure data transfer. The relevant communication protocols include:

  • TCP/IP: Fundamental for internet communications.
  • HTTP/HTTPS: Used for transferring data from the web application to users securely.
  • FTP: For file transfers between local and cloud storage.
  • SMB: To facilitate file sharing across the network.
  • VPN: Ensures secure remote access to the cloud.
  • Wi-Fi Standards (e.g., 802.11ac): For wireless connectivity at facilities.

Layered Architecture and Its Benefits

A layered architecture aids in the design and implementation of communications by segmenting and packaging functions. The layered model, such as the TCP/IP model, enables creators to troubleshoot issues effectively, as faults in communication can be isolated to specific layers. Each layer in a system has distinct tasks that can be developed and improved independently of others, facilitating agility in managing technology changes and updates.

The Four-Layer TCP Model

In the context of Mark’s cloud services and ERP system, the TCP model's four layers are:

  • Application Layer: Interfacing with user applications (e.g., ERP software).
  • Transport Layer: Ensures reliable data transfer between networks (e.g., TCP or UDP protocols).
  • Internet Layer: Handles packet routing through the network using IP protocols.
  • Link Layer: Concerned with the physical transmission of data over the network hardware.

Each layer serves a critical function, ensuring effective communication and data transfer across Mark’s multiple locations and cloud services.

Packet Transmission via TCP Model

When data packets are transmitted from the cloud server to a device, such as a tablet at Mark's facility, the process encapsulates each layer:

  • The Link Layer encapsulates the data packet for hardware transfer over local networks.
  • The Internet Layer packages the data for routing through wider networks.
  • The Transport Layer manages error-checking and ensures the ordered delivery of packets.
  • Lastly, the Application Layer presentation at the device ensures the user can access and interpret the received data.

Overall, this layered approach provides a robust framework for managing and routing data effectively between the cloud and Mark's operational facilities, enhancing system efficiency and reliability.
