$-->$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$/$Computers$,$ Router 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.

$-$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.
