Ask HN: What portion of your cloud budget is spent on VMs?

I've come up with a way of dynamically bidding on spot instances across multiple clouds that results in VM compute (bare metal or containers) that's a fraction of the normal cost (think 80%+ cheaper than reserved, 50%+ cheaper than standard spot).

But, to be worth the effort to turn this into a proper framework that you could use to run a container via Terraform, I'm trying to quantify what portion of the 'average' cloud spend is VMs, as opposed to managed SaaS products (message queues, serverless databases, S3, etc). I don't want to spend the time solving a problem if nobody has the problem anymore.

If you're reading this and work in cloud, could you kindly comment a rough % of what you've seen being spent on raw VMs as opposed to SaaS services, now and historically?

Thanks!
