Ask HN: Does a dynamically scaling cloud workstation exist somewhere?
I frequently work with some 'data science' projects that go from some MB to hundreds of GB.
Ideally I'd have a cloud terminal I'd connect to which could scale its RAM to fit my process RAM usage (and possibly scale up CPUs transparently too).
I know that you can scale up various cloud instances, but managing the runtime state is a problem. I'd like to avoid ever having to kill whatever processes I have running.
Something like Google's Live Migration would also be a good match here, if it enabled migrating to a bigger machine type without rebooting, or without otherwise losing process state.
Ideally I'm looking for something that I could transparently scale up and down, and which I could always SSH into without having to manually start/shutdown the instances.
Bonus points if GPUs could be added/removed in the same manner. Have you looked into Spark? There are managed Spark options on AWS/GCP (for example Databricks). Spark lets you do exactly what you are saying. Define minimum/maximum number of nodes, the machine capacity (RAM/CPU) and let Spark handle the scaling for you. It gives you a Jupyter-like runtime to work on possibly massive datasets. Spark is perhaps too much for what you're looking for. Kubernetes could possibly be used with Airflow/DBT possibly, for example for ETL/ELT pipelines. Ideally I'd like to extend at least the illusion of an ad hoc PC/workstation to the cloud. For me it seems like it would be less effort until I reach some ridiculous scale that requires more engineering and setup anyway.
