Strongly suggest you try doing that on a VPS, then report back

What do you think is going to happen? I tested it out on an ec2 instance just now and it seems to have worked as one would expect.

EC2 != VPS

They both offer virtualized guests under a hypervisor host. EC2 does have more offload specialization hardware but for the most part they are functionally equivalent, unless I'm missing something...

What VPS do you think this would cause problems on? Why?

well once you "need" that swap, it will be writing pages across the network due to the storage being external to the physical server, so the latency is terrible

Put swap on the “instance store” disk, not EBS.

Latency of swap is always terrible in comparison to RAM. RAM vs disk is already something ~1000x right? I've never characterized EBS vs trad ssd, but I would be surprised if it's more than 10x.

I don't think using swap as "emergency RAM" makes a lot of sense in 2025. The arguments in favor of swap which I find convincing are about allowing the system to evict low use pages which otherwise would not be evictable.

And that was like... two years ago? 1GB of RAM and actually ~700MB usable before I found the proper magik incantations to really disable kdump.

Also have used 1GB machines for literally years.

Strongly suggest you shouldn't strongly suggest.

Uh.. your link... doesn't show how a VPS can have SWAP enabled

You do understand what's being discussed... right?

Literally up the chain: https://news.ycombinator.com/item?id=45663111

Or you have a very peculiar understanding what 'VPS' means.

Hello, it's the year 2025 here. If you use OpenVZ-like ancient shit - it's on you.

So no, VPS is a proper virtualization for a 15 years. And with a proper virtualization you have the full control.
