Small company. We have an fairly robust application we built that runs on AWS that serves many clients. Our Sys Admin / Lead Developer has left the company and took with him knowledge we didn't all share.
Our other developers easily picked up the coding. As the project manager I have picked up on how to generally manage the server deployments using both Laravel Forge and AWS as needed. Having worked at a general level in AWS for a number of years, I know the basics.
I have a high level understanding of the architecture but I do not fully understand all of the relationships between the elements.
I want to document the instances, IP'S, volumes, security groups, KEYS, etc, used and how the are related. Visually if possible, or at least in table form.
I'm slowly figuring out how to find everything.
Does anyone have any suggestions on a good way to create easy to understand documentation for a system?
I'm flogging this in Excel and Powerpoint, Gliphy etc. and I find myself starting over and reworking the layouts as I see there is a new relationship that I had not previously understood.
Any tips would be appreciated.
