Migration of Standalone Application and Database from VM (Google Compute Engine) to a modern architecture, using Google Kubernetes Engine (APP) + Cloud SQL (DB) with High Availability (HA)

In another amazing project based on a real-world scenario, I acted as a Cloud Specialist to migrate the Compute Engine (VM) application and database to the Australia region.

Once the region migration was completed, the task was to modernize the application. I had to migrate resources running on Google Compute Engine (VMs) to a modern and containerized architecture using Google Kubernetes Engine (GKE) managed services, and Cloud SQL for the database layer, including high availability (HA).

Below are few screenshots:
