I rent a server with Hetzner for a few business projects and run DA on it. I pay about 34 euro a month for it, and i've got 64GB ram, Intel Xeon 8700 12 cores @ ~4.3GHz and 2x1TB NVMe drives setup with RAID1 for redundancy. It's got unlimited traffic and a 1Gbps connection. I know it's a few years old but It performs perfectly for what I want it for and as it's a bare metal server, I don't share any resources with anyone. I can thoroughly recommend Hetzner and they have some great deals also from time to time. It's all down to what you want to do with it really. Can't say i've used Digital Ocean before but heard good things also
