I've done the on prem design. I've migrated people entirely to the cloud. I specialize a little in between.
Without any shred of doubt the cloud is going to be more cost effective than self hosting for 99% of all use cases. They're priced that way intentionally. You cannot compete with Cloudflare/AWS/GCP/Vultr/Akami/Digital Ocean/etc.
My homelab isn't about scaling, production workloads and definitely isn't accessible to anyone but me. I'd argue using it in any other way defeats the purpose and shows a lack of understanding.
It's only just starting, too. It's been a fistful of days.
Things are going to go quickly. There's a lot to dismantle before midterms.
