When you're a single person running a system with thousands of users or more, it can be pretty daunting to think about going on holiday, or even relaxing for a weekend. "What if it goes down, and I'm not there to fix it?!" you ask yourself. While you can never really guarantee that nothing will go wrong, you can take some steps to minimise your risk of things going wrong.

If you've ever had to be on the receiving end of a monitoring system that uses email for alerts, you know how noisy things can get. Particularly if you're working in an agency or freelance-like environment, with dozens of client sites to maintain. You get so many emails that you start looking into integrations with third-party services like Zapier, and coming up with more and more complex rules to try reduce the noise.

When I first started building SaaS apps for side projects, it would take me a solid weekend solely to build the Stripe integration. These days, It's possible to build the whole SaaS app in one week.
