Do projects that use only serverless functions require a VPC

[gcp_learner]

If my project is using only serverless functions/applications, do I still need a VPC?  In other words the project does not have any VMs. 

Example - The project only uses API gateway, cloud functions, pub/sub and BigQuery.

Yes, my understanding is that you don't need to create or specify a VPC when using serverless functions.

On a related note, you can create VPC access connectors, to enable your serverless functions to connect to other resources in VPCs.
