“Let’s use Kubernetes.” Now you have eight problems
The odd thing about having 20 years of experience (while simultaneously being wide-eyed about new tech), is that I now have enough confidence to read interesting posts (like any post on k8s) and not think "I HAVE to be doing this" – and rather think "good to know when I do need it."Even for the highest scale app I've worked on (which was something like 20 requests per second, not silicon valley insane but more than average), we got by perfectly fine with 3 web servers behind a load balancer, hooked up to a hot-failover RDS instance. And we had 100% uptime in 3 years.I feel things like Packer (allowing for deterministic construction of your server) and Terraform are a lot more necessary at any scale for generally good hygiene and disaster recovery.
