I am using Vultr. They have very cheap VPS options and they have many different OS images i.e. I am running a CentOS and a OpenBSD instances.
They have a phenomenal service. Hard to beat their pure raw performance (NVMe, high clock CPU), they offer a host of solution from dedicated to VPS, you truly can’t beat their price (I migrated from AWS to Vultr, Vultr was 8x cheaper for the comparable AWS offering), they have global presence.
