Ask HN: How to host websites consisting of static files only?

Front-end and back-end are separating. I find myself writing more web apps that either don't require a backend or outsource it to backend as a service (Baas).

It seems a bit silly to have to deploy and maintain hosted servers with Nginx just to serve static files. Preferably, I'm looking for a managed and "one command" distributed solution with uptime guarantees, something like Heroku, but for websites consisting of static files only.

I heard people were using S3 for this, but then recall reading that S3 wasn't recommended to host websites.

How do you guys host these files? Also, how do you deal with SSL and canonical URLs (no-www)?

Thank you.
