When Cloudflare Workers launched, they said V8 isolates had some great properties for serverless-style compute:
5 ms cold starts vs 500+ ms for containers
3 MB memory vs 35 MB for a similar container
No context switch between different tenants' code
No virtualization overhead
I'm sure these numbers would be different today, for instance with Firecracker, but there's probably still a memory and/or cold start advantage to V8 isolates.
