FD: I work at Amazon, I also started my career in a time where I had to submit paper requests for servers that had turn around times measured in months. I just don't see it. Given the nature of the services they offer it's just too risky not to use as much managed stuff with SLAs as possible. k8s alone is a very complicated control plane + a freaking database that is hard to keep happy if it's not completely static.…
Managing a complex environment is hard, no matter whether that’s deployed on AWS or on prem. You always need skilled workers. On one platform you need k8s experts. On the other platform you need AWS experts. Let’s not pretend like AWS is a simple one-click fire and forget solution. And let’s be very real here: if your cloud service goes down for a few hours because you screwed something up, or because AWS deployed so…
AWS truly does let you focus on your business logic and abstracts a TON of undifferentiated work and well beyond the low hanging fruit of system updates and load balancing.
I guess put another way, providing a SaaS you need to have an SLA, those SLAs flow from SLO and SLIs and ultimately a risk profile of your hw and sw. The risk of a bad HBA alone probably means a day of downtime if you don't do things perfectly. AWS has bad HBAs, CPUs, memory, disks etc all day long every day and it's not even a blip for customers, never mind downtime. And if you don't model bad HBAs in your SLAs then your board is going to be pissed when that outage inevitably happens.
Now if you don't have SLAs and you like sysops, networkops, clusterops, dbops work then sure, YOLO.
