alt Hacker NewsI don't work on a server team, but in network/network security. My company made an announcement that they are extending our product's software lifetime to four years: 3 years standard support + 1 year high sev patches.
It seems to me in the 2020s that 5-7 years is plenty of support for a single OS release, and that OS support teams should be nimble enough to roll out new instances and migrate data at that cadence.
Did you read the blog post? Not upgrading a server for 10 years does happen. And it's fine if you get the right distribution with security updates.
