Hey, I'm currently studying Comp Sci and as part of my final year project I'd like to create a website with a serverless backend powered by Google Cloud. My idea was to create an API Gateway which connects to some cloud functions, but I can't fully get my head around how to actually achieve this.

I also have a domain with NameCheap and have configured an SSL certificate etc, and would like for the API to be accessed via api.exampledomain.com , how can I do this? I read somewhere that I need a Load Balancer to achieve this, but I am unsure (and it seems like an unnecessary layer, but again, I'm not sure).

For reference, I am wanting to create a backend to upload Counter-Strike 2 demos to via MatchZy (a plugin) and store them in a bucket. This page covers the functionality I'm hoping to achieve: https://shobhit-pathak.github.io/MatchZy/gotv/

Any help would be appreciated, and I can answer any questions in case I haven't been in depth enough. Thanks in advance
