Notes on reliability, cloud cost and AWS by Abhinav C.
- Your certificate will expire on a SaturdayIt's a law of nature. Certificates expire on weekends, around 2 a.m., while the person who renewed it last year is on a beach with no signal.
- The most-deployed untested code in your company is BashBash runs your entrypoints, your deploys and your backups, and almost nobody reviews it like code. Five failure modes that strict mode does not catch, and a line for when to stop.
- The cheapest EC2 instance is the one you turned offEvery cost review I've run starts the same way. Someone opens Cost Explorer, sorts by service, and EC2 sits at the top like it pays rent. It doesn't. You do.
