I am new to selfhosting and currently prefer it much more than buying a VPS or using a cloud service; having 100% control over my hardware specifications and permissions makes me just feel safer. While right now I have it currently just hosting a simple game server for my friends, I do want to expand it to other things, such as hosting a website and a small database.

However, I have currently run into the issue where I have reached the bandwidth limits provided by my ISP, which is a surprise to me, since I didn't expect to hit it, but once I've opened the server this month, it is the first time I've received a warning about it.

Only trusted people have access to my server, so I am fairly certain that I just underestimated the amount of traffic that there would be in and out, but I am now wary if selfhosting for my other ideas is possible if I get bandwidth limited so fast.

If bandwidth limitations is a very strong barrier to selfhosting, what are alternatives/services that you guys recommend?

Thanks!
