Скачать или смотреть RailsConf 2023 - Zero downtime Rails upgrades by Ali Ibrahim

No one likes working on Rails upgrades, and who can blame them? They can be thankless, time-consuming, and—worst of all—unpredictable. How long will they take? When can we get back to feature work? What’ll break when they’re deployed? It’s tempting to say, “Let’s do it later,” but later is usually never. Instead of living in fear of the big, scary Rails upgrade, your team can set up systems for incremental change that let you:

continue feature work
deliver predictable results
seamlessly jump into the next upgrade (because there’s always a next upgrade)

And I’m gonna show you how.

In the years since I’ve worked on upgrading Rails at GitHub, I’ve refined this approach to Rails upgrades and successfully implemented it at several organizations. In this talk, you’ll learn everything you need to burn down uncertainty and boldly go into your next Rails upgrade.
