If you are using AWS, Google, Oracle, or Azure and are just using VMs, you are getting horribly ripped off. There is absolutely zero advantage to using these for just compute. None. They only make sense in a business setting if you are leveraging their managed services to save on labor costs, or if you need to elastically scale to really enormous sizes and have confidence that you won't run out of resources.
VPS providers like Digital Ocean, Vultr, or Linode charge for bandwidth overages but their costs are generally at least an order of magnitude less than the big cloud vendors.
If your primary concern is cost consciousness, and when your failure case is "get slow and fall over" and you're OK with that, this makes sense. For the OP, who doesn't seem to have a profit motive, I think this is good advice.
The caveat I would add is that a lot of folks try to extrapolate from personal stuff into the small-business (opposing "startup" -- that is, not swimming in VC money) realm, and it's easy to staple your hand to your face when looking at video in that way. Balancing cost controls against quality of service is kinda pretty hard for video because engagement is tied in pretty tightly to time-to-first-frame and to consistency of the video stream coming down, and even a well-provisioned set of boxes in an OVH datacenter somewhere are going to have more trouble with latency as well as bandwidth to geographically distributed clients. Yeah, you can fix this...by building your own CDN out of multiple points of presence at multiple data centers, but there are economies of scale to just paying your local friendly CDN overlords to ship your stuff from their POPs. Not all video usage is directly tied to revenue, though, which is why I characterize it as risk: the particulars of your venture may be such that the risk of higher costs due to sudden popularity is worth the quality of service during the 99.9% period for your users who aren't local to your point of presence. But there are no hard-and-fast rules here.
But, yes, in general for an individual hobby site, I'd choose an option that resulted in a hug of death rather than a big bill.
And, as peer says, discoverability unless you already have an audience.
