Ask HN: How do you make sure your servers are up as a single founder?
I am a solo founder of a website monitoring SaaS [0]. Theoretically, my uptime should be higher than that of my customers'. Here are a few things that I found helpful in the course of running my business:* Redundancy. If you process background jobs, have multiple workers listening on the same queues (preferably in different regions or availability zones). Run multiple web servers and put them behind a load balancer. If you use AWS RDS or Heroku Postgres, use Multi-AZ deployment. Be mindful of your costs though, because they can skyrocket fast.* Minimize moving parts (e.g. databases, servers, etc..). If possible, separate your marketing site from your web app. Prefer static sites over dynamic ones.* Don't deploy at least 2 hours before you go to sleep (or leave your desk). 2 hours is usually enough to spot botched deploys.* Try to use managed services as much as possible. As a solo founder, you probably have better things to focus on. As I mentioned before, keep an eye on your costs.* Write unit/integration/system tests. Have a good coverage, but don't beat yourself up for not having 100%.* Monitor your infrastructure and set up alerts. Whenever my logs match a predefined regex  pattern (e.g "fatal" OR "exception" OR "error"), I get notified immediately. To be sure that alerts reach you, route them to multiple channels (e.g. email, SMS, Slack, etc..). Obviously, I'm biased here.I'm not gonna lie, these things make me anxious, even to this day (it used to be worse). I take my laptop everywhere I go and make sure that my phone is always charged.[0] https://tryhexadecimal.com
