Time to talk: An update
Added 2020-02-22 08:11:20 +0000 UTCSimply put:
Well, the time for my AWS Credit to run out is coming close, but after doing some research and some performance optimizations in general, I have managed to reduce the server costs considerably, the main change was that I was able to drop the RAM usage by a whole GIGABYTE, took some time tinkering and trying out a bunch of stuff until I could figure out how to make things work better.
The Technical stuff:
I run the services in my server in Docker Containers for ease when moving from development to production. The problem was that because of a limit for max open files(1024 by default), when the extension reached too many users, it'd essentially be unable to open new connections.

(Note: Both Nginx servers were in Docker containers to solve the max open files issue, this was a relatively recent change)
However, because of some configuration issue or some other problem that I was unable to figure out with the short time I wanted to spend on it, the Application load balancer had incredibly high CPU/RAM usage. So removing it was crucial, which led to the next(current) setup:

The only inconvenience is that scaling the application has become more troublesome and would require more work. Instead of being a single command line argument, I have to update both config and docker-compose files, which would be just that, an inconvenience and it'd make scaling take longer to perform but that would be it.
What this means:
Since server costs have dropped and so has the monthly goal, and so long as the Goal is fulfilled, the captions will be kept running. If it is not fulfilled, it will all depend on how much I can put out of my own pocket to cover the costs that month. I'm in a tight financial situation while also trying to save money to go to TwitchCon, so it is hard for me to throw my own money at it, but ALL of the Patreon money will go directly to server costs and what's left at the end of each month will be saved for the future in case the goal is not fulfilled.
Again, thanks to all the patrons helping keep the project going, I appreciate you all. <3
