Also, just take an old phone from your drawer full of old phones, slap some free camera app on it, zip tie a car phone mount to the crib, and boom you have a free baby monitor.
I'm glad both me and my kind grew up in different times.
Today's kids will never in their lives know what freedom is, and we are guilty we made such dystopian societies a reality.
I got a new phone because I thought my battery was cooked, but turns out it was just the app.

> It turns out that when AWS says an instance can do “Up to 12.5 Gbps”, that’s burstable networking backed by credits; when you’re below the baseline, you accrue credits and can burst for short periods.
Yes, AWS has a burst rating and a sustained/baseline rating for both EBS types as well as instance types. Use https://instances.vantage.sh/ (and make sure you choose specific columns) to compare specific criteria and then export as a CSV to find the lowest price that matches your performance/feature/platform criteria. Design to the baseline if you need guaranteed performance. Do sustained performance testing.
> When we Terminated connections idle >10 minutes, memory dropped by ~1 GB immediately; confirming the leak was from dangling sockets. Fix: make sockets short-lived and enforce time limits.
We used to do that with Apache 20 years ago. Config option forces a forked subchild to exit after N requests to avoid the inevitable memory leaks. AKA the Windows 95 garbage collector (a reboot a day keeps the slowness at bay).
FWIW, if the business feasibility of your architecture depends on custom stuff, performance enhancements, etc, you will find that you eventually have harder and harder problems to solve to keep your business functioning. It's more reliable to waste money on a solution that is brainless, than invest human ingenuity/technical mastery in a solution that is frugal.
On the other hand, S3 is kind of ridiculously expensive compared to even more expensive on-prem options like a PureStorage SSDs array. With spindles on Ceph you can probably get quite a bit lower than AWS's 2c/Gig/mo. Or you can just use R2 with colocated servers for ingest.
