Google Cloud - Global Application Load Balancer HTTPS¶

Step-01: Introduction¶

Pre-requisite-1: Create Instance Templates, Create Managed Instance Groups as part of Section Cloud-LoadBalancer/01-Managed-Instance-Groups
Create Global Application Load Balancer - HTTPS with Google Managed SSL Certificates

Step-02: Create Global HTTPS Load Balancer¶

Go to Network Services -> Load Balancing -> CREATE LOAD BALANCER
Select Application Load Balancer (HTTP/S): START CONFIGURATION
Internet facing or internal only: From Internet to my VMs or serverless services
Global or Regional: Global external Application Load Balancer
Load Balancer name: global-lb-external-https-google-managedssl

Frontend Configuration¶

Click on ADD FRONTEND IP AND PORT
Name: frontend-https-google-managedssl
Description: frontend-https-google-managedssl
Protocol: HTTPS
IP Version: IPv4
IP Address: global-lb-ip3 CREATE NEW EXTERNAL STATCI IP
Port: 443

CREATE GOOGLE MANAGED SSL CERTIFICATE¶

Click on CREATE A NEW CERTIFICATE
NAME: app1-google-managed
Description: app1-google-managed
DOMAINS: myapp1.kalyanreddydaida.com, myapp1.stacksimplify.com
Click on CREATE
Enable HTTP to HTTPS Redirect: enabled
Click on DONE

Backend Configuration¶

CLick on CREATE A BACKEND SERVICE
Name: mybackend-svc1
Description: mybackend-svc1
Backend type: Instance Group
Protocol: HTTP
Named Port: webserver80 (AUTO-POPULATED WHEN BACKEND IS SELECTED AS mig1-lbdemo)
Timeout: 30
BACKENDS
Instance Group: mig1-us-central1
Port Numbers: 80
REST ALL LEAVE TO DEFAULTS
Click on DONE
Instance Group: mig1-us-east1
Port Numbers: 80
REST ALL LEAVE TO DEFAULTS
Click on DONE
Disable Cloud CDN
Health Check: http-health-check
Security:
Cloud Armor backend security policy: NONE
Click on CREATE

Routing Rules¶

Mode: Simple host and path rule
REST ALL LEAVE TO DEFAULTS

Review and Finalize¶

Review all settings
Click on CREATE

Step-03: Verify Load Balancer¶

Go to Network Services -> Load Balancing -> global-lb-external-https-google-managedssl
Review the Tabs
LOAD BALANCERS
BACKENDS
FRONTENDS

Step-04: Verify SSL Certificate in Certificate Manager¶

Goto Security -> Certificate Manager -> Data Protection
Click on CLASSIC CERTIFICATES -> app1-google-managed

Step-05: Add DNS Recordset in your desired Domain Provider¶

Create LB IP as A record in your DNS Provider
In my case, I have a registered domains in Google and AWS
So we will use Google Cloud DNS and AWS Route53
We will create a RECORD SET in Google Cloud DNS and AWS Route53
Important Note-1: WAIT FOR 1 to 2 hours for Google Managed SSL certificates to be provisioned and ACTIVE
Important Note-2: Just to prove that not only Google Cloud DNS, it works on any DNS provider (if we just add our LB IP as A record to verify our domain before creating valid SSL certificate for that domain by Google managed SSL servide)
Additional Reference: https://cloud.google.com/certificate-manager/docs/deploy

Step-06: Popular Domain Registrars¶

Namecheap
GoDaddy
BlueHost
AWS Route53
Google Cloud Domains

Step-07: Access Application using LB IP on browser¶

Important Note: WAIT FOR 3 to 5 Minutes before Load Balancer is fully operational

# Access Application - HTTP
http://myapp1.kalyanreddydaida.com
http://myapp1.stacksimplify.com
Observation: Should redirect to HTTPS URL

# Access Application - HTTPS
https://myapp1.kalyanreddydaida.com
https://myapp1.stacksimplify.com

Step-08: Delete Load Balancer¶

Delete the Load balancer created as part of this demo.
