Could you, please, provide more details on this? I'm searching for the same solution. I'm planning a blogger-like static site generator. All media will be on external resources, and I want to keep maintenance price to a minimum (preferably zero) cost. Thanks.
Sure - we use Contentful as our cloud based CMS offering. There are a few other players here - but the only ones I can speak to would be Prismic and Siteleaf, both of which are really solid.
Once you've got your content CMS-side, you can then pull that content into your SSG during the build process. All of those offerings I mentioned also have webhook support, so on publish of any content you can refire the build (to then pull down the new content).
We are loving this setup. There are really very few downsides.
