It is just a bunch of docker containers. Some run in tasks and some run as auto-scaling services. Would probably take a week to switch to AWS as there are equivalent managed services there.
But this is really a spurious concern. I myself used to care about it years ago. But in practice, rarely do people switch between cloud providers because the incremental benefits are minor, they are nearly equivalent, there is nothing much to be gained by moving from one to the other unless politics are involved (e.g. someone high up wants a specific provider.)
How does the orchestration work? How do you share storage? How do the docker containers know how to find each other? How does security work?
I feel like Kubernetes' downfall, for me, is the number of "enterprise" features it (got convinced into) supporting and enterprise features doing what they do best: turning the simplest of operations into a disaster.
I use managed DBs and Cloud Storage for shared storage. I think that provisioning your own SSDs/HDs to the cloud is indicative of an anti-pattern in your architecture.

You can configure Cloud Run services to be internal only and not to accept outside connections. Otherwise one can just use JWT or whatever is normal on your routes in your web server.
Yup domain mappings for now. There is some label support in Cloud Run but I haven’t explored it yet. You can also get the automatic domain name for a service via the cloud run tools.
Yeah I definitely want to also avoid a load balancer or gateway or end points as well for cost purposes.
One of Cloud Run's main advantages is that it's literally just telling it how to run containers. You could run those same containers in OpenFaaS, Lambda, etc relatively easily.
