Ask HN: What resource allocation strategies do IaaS providers use?

This is a classic case of multidimensional bin packing problem. The problem of assigning VMs to PMs is known to be NP-Hard. It would be great to understand/know a high level solution ignoring the detailed complexity (SLA etc.)

"It's just bin-packing!"

I think you'll find that most IaaS providers largely follow the latest heuristics in established bin-packing literature.

constraint satisfaction came up during our discussion.. wonder if that would provide an appropriate solution at scale
