Not using SASS services (e.g. Firebase) just really sucks though.
We still use it (started with it before privacy shield was demolished) but we will have to migrate eventually. Don't know what we'll use exactly, maybe managed kubernetes with some platform for an easier workflow running on it? Idk yet.
And if you already consider Kubernetes, even better. It removes a lot (but not all) of headaches for managing infrastructure. I wish there was better market for quality k8s operators to automate the management tasks for some specialized deployments.
It is open source, the hosted vendors will emerge, so you will be able to buy it, if not yet.
That said, I sympathize. Re-doing already done feature rather than focusing on new things can feel discouraging.
