Mark Peterson acquired a $3$D printer in late $2015$ and established a business creating assistive and accessibility devices. His business has grown, and he now plans to expand operations by adding more $3$D printers, a $3$D scanner, and hiring additional employees. To support this growth, Mark aims to set up an IT infrastructure, implement an enterprise resource management system, and provide mobile access to his employees. He wants to store production and management files locally while using cloud storage for backup. Mark also intends to replace his spreadsheet of customer orders with a small business enterprise resource management $($ERP$)$ system and wants his employees to be able to update the inventory system as well as access the $3$D printing systems through a mobile device.

Mark has successfully implemented IT infrastructure recommendations and his $3$D printing business is thriving. His father wants to invest in opening two more facilities near Veterans Administration Hospitals in Memphis, Tennessee, and Phoenix, Arizona. Mark is eager to expand his business and help service members with his $3$D printed accessibility and assistive devices. He plans to retain the server and storage devices he has already purchased and utilize high$-$speed internet connections to download $3$D design files instead of storing them at each new location. Each new facility will have the same number of $3$D printers and staff as the current location, with employees needing access to the ERP system for time reporting and supply ordering.

$-->$List A$-$To accommodate Mark's two new facilities, here is a list of the components that will be needed at each new remote location:

$3$D Printers,$3$D Scanners,Workstations$/$ComputersRouter and Switch, Cable for Ethernet, Wireless Access Points, FiOS Internet Connection, Local Area Network $($LAN$),3$D Modeling Program, Slicing Programprinters., ERP Applications, Firewall and Antivirus Protection, VPN $($Virtual Private Network$),$Google Email, Encryption of Data, Firewall Protection, Tablets$/$Laptops$,$Mobile Devices $($e$.$g$.,$ cell phones$),$VPN Gateway, Cloud$-$Based ERP Database Access, The VPN and encryption

$-->$List B$-$The changes needed in Mark's current IT infrastructure

Mark's existing IT infrastructure will need several updates and expansions to manage the increased demands effectively.

Server and Storage Upgrades, Upgraded Network Infrastructure, VPN Enhancement

Enhanced Security Measures, ERP System Scalability, Backup and Disaster Recovery Plan Enhancement, Communication Tools Upgrade, Network Infrastructure Upgrades in the Main Facility, Scalable Storage Solutions, Monitoring and Management Tools

It is now a year later, and Mark has opened his two new facilities in Memphis, Tennessee and Phoenix, Arizona.$$ All three locations are operating almost around the clock to create $3$D printed accessibility and assistive devices.$$ 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.

$-$Provide an introduction that explains what is contained in the paper.$$

$-$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.$$

$-$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.

$-$List the protocolinvolved 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.

$-$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.
