What is a necessary step to perform before using Function Compute with VPC resources?

Before using Function Compute with Virtual Private Cloud (VPC) resources, establishing a connection with the VPC is critical. This step ensures that the Function Compute service can communicate effectively with other resources that reside within the VPC, such as databases, servers, and other services. When you create a connection to the VPC, you essentially allow Function Compute to access resources securely and privately, leveraging the network capabilities offered by the VPC.

Setting up this connection involves specifying the VPC ID and subnet details, which grants the necessary networking capabilities required for the functions to execute in an isolated environment. Without this connection, Function Compute would not be able to reach the resources in the VPC, limiting its functionality and the potential use cases that require VPC access.

While IAM permissions and function execution roles are important for access control and function execution privileges, they do not directly establish the required network connectivity to VPC resources. Similarly, setting up billing alerts is useful for monitoring costs but does not impact the technical connectivity aspect that is crucial for Function Compute operations within a VPC.
