Creating a Virtual Private Cloud (VPC) in GCP


A Virtual Private Cloud (VPC) is a network that you can customize in Google Cloud Platform (GCP). It allows you to isolate your resources, control network configurations, and securely connect to your virtual machine instances. Creating a VPC is one of the foundational steps for building your infrastructure on GCP.

Key Concepts

Before we dive into creating a VPC, let's understand some key concepts:

  • VPC Networks: VPCs are global, and each project can have multiple VPCs. They provide the network foundation for your GCP resources.
  • Subnets: Subnets are subdivisions of VPC networks, and they define IP ranges in specific regions.
  • Firewall Rules: You can control incoming and outgoing traffic using firewall rules associated with a VPC.

Creating a VPC

To create a VPC in GCP, you can use the following gcloud command:

    gcloud compute networks create my-vpc --subnet-mode=auto

This command creates a VPC named "my-vpc" with subnet mode set to "auto," which means Google Cloud will automatically manage IP addressing for the subnets within the VPC.

Creating Subnets

After creating a VPC, you'll typically want to create subnets within it. Here's an example command to create a subnet:

    gcloud compute networks subnets create my-subnet --network=my-vpc --region=us-central1 --range=

This command creates a subnet named "my-subnet" in the VPC "my-vpc" in the "us-central1" region with the IP range ""


Creating a Virtual Private Cloud (VPC) is a fundamental step in setting up your network infrastructure in Google Cloud Platform. It allows you to customize your network configuration, control access, and securely connect your resources. Explore more advanced features and configurations in the GCP VPC documentation.
