Task:

• Create a Custom VPC
• Configure a Firewall Rule
• Configure Backend Service and create an Unmanaged Instance Group
• Create a Health Check
• Configure Front End Configuration and test the Load Balancer

Solution:

Task 1: Create a Custom Mode VPC

Under VPC Network | Click on Create VPC Network

Under Create a VPC Network | Name: dclessons-vpc | Subnets: custom | New Subnet: Name: dclessons-ipv4-subnet | Region: us-central1

IP Stack Type: IPV4, | IPv4 range: 10.0.1.0/24 | Private Google Access: Off | Click Done

Under Subnet | Subnet Creation Mode : Custom | Select dclessons-ipv4-subnet and Click Add Subnet

Under New Subnet | Name dclessons-ipv6-subnet | Region: us-central-1 | IP Stack Type: IPv4 and IPv6 (dual stack )  IPv4 range : 10.0.2.0/24  | Click Done and leave a other setting as it is.

Under Firewall Rules | Choose all rules mentioned and Under Dymanic Routing Mode: Select Regional | Click Create

Task 2: Create a Firewall Rule:

Login to GCP Console | Click on VPC Network | Click on Firewall

Provide Name: dclessons-ipv4-traffic | Logs: off| Network: dclessons-vpc, priority 100 | Direction of traffic: ingress| Action: Allow | targets: specified targets tags | target tags : allow-ipv4 |Source IPv4 ranges: 0.0.0.0/0

Protocols & Ports: Select Specified protocols and Ports | TCP: port 80 | Click Create

Create another Firewall rule :

Login to GCP Console | Click on VPC Network | Click on Firewall

Provide Name: dclessons-allow-ipv6-traffic | Logs: off| Network: dclessons-vpc, priority 101 | Direction of traffic: ingress| Action: Allow | targets: specified targets tags | target tags : allow-ipv6 |Source IPv4 ranges: ::/0

Protocols & Ports: Select Specified protocols and Ports | TCP: port 80 | Click Create

Task 3: Configure & Create VM Instance

Under Compute Engine | VM Instance: Create Instance

Under Create Instance | Name: dclessons-instance-1 | Region: us-central1(lowa) , Zone: us-central1-a | Machine Configuration: Series : N1 , Machine Type: n1-standard-1

Under Identity & API Access | Service Account: Select No Service Account

Under Advance Option | Networking: Network tags: allow-ipv4

 Network Interfaces: Edit Network Interfaces: Network: dclessons-vpc | Subnetwork: select dclessons-ipv4-subnet IPv4(10.0.1.0/24) | Click Done

Under Management | Automation put below code:

#!/bin/bash
apt update -y 
apt install -y apache2
apt install -y php
echo "Hello dclessons Single Stack Instance, I have IPv4 IP Address" > /var/www/html/index.html

Leave the rest of the settings as default and click on Create.

Lets Create One more Instance

Under Create Instance | Name: dclessons-instance-2 | Region: us-central1(lowa) , Zone: us-central1-b | Machine Configuration: Series : N1 , Machine Type: n1-standard-1

Under Identity & API Access | Service Account: Select No Service Account

Under Advance Option | Networking: Network tags: allow-ipv6

 Network Interfaces: Edit Network Interfaces: Network: dclessons-vpc | Subnetwork: select dclessons-ipv6-subnet IPv4(10.0.2.0/24) | IP Stack Type: IPv4 and IPv6 (dual Stack) Click Done

Under Management | Automation put below code:

#!/bin/bash
apt update -y 
apt install -y apache2
apt install -y php
echo "Hello dclessons Dual Stack Instance, I have both IPv4 and IPv6 IP Addresses." > /var/www/html/index.html

Leave the rest of the settings as default and click on Create.

Now you can see that your both Instance is created.

Task 4: Configure Instance Group

Click on Compute Engine | In Left Side bar: Click on Instance Group

Under New Unmanaged Instance Group | Name: dclessons-instance-group-1 | | Region: us-central1(lowa), Zone: us-central1-a
