For a static blog you dont need that. My blog made the (near bottom of) HN front page last year. I didn't notice a thing until I looked at the traffic report (using goaccess). Static site generator with the result served from a bottom of the barrel Hetzner VPS, using nginx.

If a blog needs "scaling" of any sort you are doing it wrong.

Even hacker news itself runs on a single server without any scaling.
