Can you explain AWS/GCP VPCs to me? Here's my understanding..

I am learning CCNA concepts and networking concepts since past couple of months.

Correct me if I am wrong.

Apologies in advance if this question makes no sense

We can subnet our local router and assign the fast ethernet port that subnet IP and mask. If there are two fast ethernet ports we can create two subnets and connect them to two switches.

So, is VPC just like that? When I create a VPC in say AWS, AWS spins up/powers up a router for me? And when I create subnets in that VPC, a command similar to 'ip address 10.0.1.0/24 s/0/0' is being run on the router that was created?

Thanks for reading. Have a good day.
