Connecting IoT Devices to a Registration Server (Packet Tracer, Cisco)

In Packet Tracer, a demo software made by Cisco Systems. It certainly has changed a lot since 2016. It's almost an Olympic feat to even get started with it now, but it does look snazzy. This is for the new CCNA, that integrates, among other things, IoT and Automation, which I've worked on here before. Instructions here . I don't know if this is an aspect of "Let's make sure people are paying attention and not simply following blindly", or an oversight - The instructions indicate a Meraki Server, when a regular one is the working option here. I have to enable the IoT service on this server. Also, we assign the server an IPv4 address from a DHCP pool instead of giving it a static one. For something that handles our IoT business, perhaps that's safer; Getting a new IPv4 address every week or so is a minimal step against an intruder, but it is a step. There are no devices associated with this new server; In an earlier lab (not shown), I attached them to 'H

The general idea in this CRM Development is: To have a GUI to add people to a NRM (Network Relationship Management). Attach it to a database (MySQL is what I went with eventually using Amazon Relational Database service, but you can use PostGRES, and probably others). Make sure components are connected to each other in the retool interface. This video is a good start. Watching the tutorial video, heard some SQL commands and went 'Oh no 😳" before going "Wait I know basic SQL", which is good, because you'll see. When you get set up, there's a plethora of resources you can use -- Incl
