Ahem

s/Spring/Sling/ I assume :-)

You might also be interested in the  'Internet Scale Content Management
with Apache Oak on Kubernetes' adaptTo talk [1] which looks relatively
close to your scenario.

You'll have to be more explicit about that. The DocumentNodeStore
documentation in Oak [2] should contain most of what you need to know.

You are probably interested in 'Background read' - DocumentMK
periodically picks up changes from other DocumentMK instances by
polling the root node for changes of _lastRev. This happens once every
second. That means that if something is changed on Instance A, Instance
B will see it in at most one second.

To my knowledge, yes.

Content packages are one way of doing that. Changes can either be
performed using Sling content distribution [3] or by using the Package
Manager APIs. As a package manager you can use the Composum one [4]
coupled with the wcm.io content-package-maven-plugin [5].

Again, you need to more specific here. Is a SPA deployed in Sling? Or
deployed externally and consuming Sling output?

At any rate, peregrine CMS [6] is a SPA built with vue.js on top of
Sling so you might want to check that out.

Everything is content, including translations :-) So what I wrote above
related to content deployments still stands. Also, just in case you
missed the reference page, the documentation for i18n support is at
[7].

Hopefully that gets you started. Feel free to come back with more
questions if needed.

Thanks,
