Good article. My comment might be off topic in which case, please ignore.

If you have a one-person SaaS company, how do you get past customers’ resistance to a single point of failure, namely you?

Do you pretend you’re not just one person? Do you only have customers who could handle losing the service when you, say, run away to meditate on the mountaintop? (Or get run over by a beer truck, or whatever.) Is there some non-obvious solution?

And — back on topic — is the architecture part of that sales pitch? “I’m just one dude, but look how simple this is, it can run itself if I am devoured by mice!”
