Can people expect Cold Start to disappear in the future?

Hello there,

Can we assume in the short term (1 - 3 years) cloud providers will figure out a way of getting rid of cold start for good? Even on VPC?

Unikernel and container technologies are evolving so fast that I would bet FaaS will be VIRTUALLY cold start free in all situations and we won’t need the dirty warm up hack anymore.

What’s your opinion?

I think that completely depends on the cloud providers. If they care about the cold start seriously, they have to keep the function warm, although it imposes some additional costs for them. I think they had not expect how much the cold start would bit the users, otherwise they would have set a higher cost for the FaaS and in return would have kept the functions warm or pre-fetched at least.
