We don't need unikernels. The technology for running containers securely has existed for years. The only problem is that few mainstream/major cloud providers support them, it requires nested virtualization among other things. And your traditional companies like AWS and GCE make you pay out of the nose for it because if it becomes widely available, then the whole "Serverless", elastic container service etc. industry may be eroded. Right now you have two choices: run your own co-location bare metal server with all the complexity that comes with it, or pay for a VPS with nested virtualization support that is a magnitude more expensive.
