Project Athens
==============

Project Athens is an effort to consolidate my own online presence
onto a common platform that is not only easier to maintain
but also more managable from an operations pov.

Most of the code in this repository has to do with the infrastructure
of the project which is used to host services that I host myself.


Section 1. Preamble/Abstract
============================

This explanation will take on a bottom up approach because the technical
goals/processes are what make up the deliverable value(to myself).

Also this project is just for me so fuck off if you don't like it.


Section 2. The Hosts/Services
=============================

Services to host are listed below with their respective roles:

Docker host:
	- Discord Chat Bots
		- Lewdlad(Server Management Chat Bot)
		- Musical Maurice(Music Voice Bot)
	- My personal clippable instance

Static Nginx server:
	- Personal Website
		Served under shockrah.xyz
	- Resume Website
		Served under resume.shockrah.xyz
	- Frechat Documentation
		Served under freechat.shockrah.xyz

SSH/Ansible Host
	This is the dev box that I use to patch things in the
	VPC. This way we only accept internal SSH connections.
	Rationale: To reduce surface area to the outside werld

Reverse Proxy
	This server is going to sit between Alpha & Beta as
	both are going to need need to take HTTP requests
	from the internet but I don't want to expose them.

Section 3. Codenames
====================

Below are the codenames which Terraform code uses in order to 

Alpha - Docker host

Beta - Static Nginx Server

Gamma - Dev/Ansible host

Sigma - Web App Reverse Proxy

Crete - Primary Subnet used to host stuff

Section 4. Network Layout
=========================


Crete
	Subnet 10.0.0.128/26
	Refers to the primary subnet that most services live on.
	Contains its own internet gateway as services here
	basically require 24/7 internet access.
		> High number of web services


Alpha
	Internal IP: 10.0.0.151
	Web Docker Host

Beta
	Internal IP: 10.0.0.152
	Static Web Server

Gamma
	Internal IP: 10.0.0.153
	Has an EIP bound however the server is only up when required.

Sigma
	Internal IP: 10.0.0.154
	Reverse Proxy for Alpha and Beta. Doing this means we don't have
	to assign EIP's for every single one.


Section 5. Image's Used for Hosting
===================================

Primary Image Used
	AMI - Ubuntu Impish 21.10
	Rationale - Basically the latest release by cannonical
	which I'm kinda just trusting they got things right xd

Firewall setup
	Most of the firewall setup sits in AWS however they
	should probably be mirrored on each host in case one
	of these layers fails for some reason.
		- TODO: This is going to have be be done via Ansible

Instance Types with rationale
	Alpa - t3.small(Maybe)
		Slightly heavier because it must run multiple
		chatbots and clippable but all are extremely
		lightweight. This might have to be pushed later
		to medium but for now it's fine.
	Beta - t3.micro
		Nginx server
	Gamma - t3.micro
		Ansible host
	Sigma - t3.small
		Using a small since we only need enough power
		to supply a load balancer(of sorts). Also some
		of the workers behind this are kinda large which
		means we can't scrape by with something tiny
