Steps To Create VPC Network In GCP

Step 1: Open Google Cloud Console

• On your web browser, visit console.cloud.google.com and Login with your valid credentials.
• You must have a valid Google Cloud’s subscription to continue with the further steps.
• Once you are on the homepage of Google Cloud Console, create a project with some valid name.

Step 2: Enable Compute Engine API

• In order to be able for creating VPC networks, we need to enable Compute Engine API which provides functionalities for managing VPC Networks, subnets and other related resources.
• Use the search-bar available to search for Compute Engine API and click on the search result.

• Click on ENABLE and wait for sometime for it to be enabled, then go back to the Google Cloud Console’s homepage.

Step 3: Open VPC Network

Use the left sidebar available, scroll down there and look for “VPC Networks” and click on it.

• This will open the VPC Network’s page. Here you can see the default VPC Network has already been created for you.

• You can use this VPC Network for learning purposes but it is not recommended to be used for production purpose.
• In you have on-premises server or have multiple VPC then there is a chance that this default- VPC may overlap.
• It is always better to create a new VPC Network for your projects and production.

Step 4: Create VPC Network

• Click “Create VPC Network” button available there which will open a new page to fill basic details about your VPC Network and options to configure and customize.

Step 5: Fill Out VPC Network Details

• Give a name to your VPC Network and write a description for it. Description is not mandatory, so if you want you can skip it.

• Leave the MTU or Maximum transmission unit as it is. MTU simply defines the largest packet size of the network.
• It can be set to any value between 1300 and 8896. The Default value is 1460. Disable the VPC network ULA internal IPv6 range.

Step 6: Configure Subnets

We will be choosing custom in subnet section, so we can define our subnet ranges. If you select automatic it will be the same as the default VPC network as it will create one subnet in each region with default values.

• Let’s Create two different subnets in different regions. You can choose the IP Stack type while creating subnets, here we will be selecting IPv4 for each subnet.

For the first one,

• Name: subnet1
• Region: us-west1
• IPv4 : 192.168.1.0/24

You can write a description if you want, we will here leave other options as it is.

Let’s create another subnet as

• Name: subnet1
• Region: us-east1
• IPv4 : 10.1.0.0/24

Step 7: Configure Firewall Rules

• If the firewall rules section you can see rules are already created for you with the IP addresses you have selected.

• The first rule defines that all the VMs in your VPC network can have incoming connection request on all ports inside the VPC Network.
• The second rule will allow anyone on the internet to ping your instance created in the VPC Network.
• The next one allows anyone over the internet to use remote desktop connection with the instances on your VPC and the next one allows will allow to use the SSH over the internet with valid keys.
• These four rules will be evaluated first then the next two rules will be evaluated. The next two rules defines deny all access and allow all access to the instances in the VPC Network.
• Choose the firewall rule which suits the best for you. You can edit the rules later or can create new rules once your VPC Network is created.

Step 8: Review And Create

• In the next section of Dynamic routing mode select the default mode which is Regional.
• You can also create DNS Policy if you want but these things are optional.
• Check all the configurations you have done to the VPC Network and once checked by yourself, click on the Create button to create the VPC Network. It will take few minutes to create.

The other way

• You can also select Equivalent Command line to generate command line code for the VPC Network with the configurations you have done, run it on Cloud Shell to create the VPC Network.

Step 9: Check Your VPC Network

• Once you see the message “Created” search for VPC Networks on the search bar and select it to navigate in the VPC Networks’ Homepage to verify the creation of your VPC Network.

• Now you can see the VPC Network “geeksvpc” in the VPC networks section with the default one means our VPC Network has been created successfully.
• You click on geeksvpc to get a overview of it with customization and configuration options and the priviledge to delete the VPC Network.

• You can explore all the other options available to check and change the configurations made as per your requirement.
• For example let’s check the subnets section and see what we get.

• As you see, we get the option to add new subnets and it’s showing us the subnet we have created with it’s IP ranges.

A VPC or Virtual Private Cloud allows you to secure your virtual networking environment including IP addresses, subnets, and network gateways. VPC allows users to create a virtually protected environment for their virtual instances on the Cloud platform and have complete access to the environment. VPC provides users the facility to place and manage necessary resources in a virtual protected environment of the cloud provider like Google Cloud Platform(GCP). We as a user can create, customize, and delete VPC networks in GCP. In this article, we will be exploring how we can create a VPC network in the Google Cloud Platform.
