In principle, the two are very similar. However, the way we implement it is similar to database replication. Once a static page is produced, we can store it for usage across the entire edge network. This means you get the benefits of traditional static generation too: less backend load, higher availability, lower latency.

Haha, that’s true. I guess the advantage to NextJS is it comes “batteries included” - you don’t have to worry about setting up a cache etc. Obviously for some use cases setting it up yourself will make more sense

As they say, "Get a framework that'll do both."
