Google Cloud architecture template
Google Cloud 3-tier web app
Global Application Load Balancer with Cloud Armor and Cloud CDN, Compute Engine instance groups, Cloud SQL and Memorystore.

When to use it
Use this template for a traditional web application on Google Cloud. A global external Application Load Balancer gives users a single anycast IP address, Cloud Armor applies WAF and DDoS rules on it, and Cloud CDN caches static responses at the edge. Static assets are served from a Cloud Storage backend bucket. Dynamic requests go to a regional managed instance group of Compute Engine virtual machines that autoheals and autoscales. Cloud SQL for PostgreSQL in high-availability mode holds the data over a private IP, and Memorystore for Redis keeps sessions out of the instances.
Instance groups give you full control of the runtime but leave patching and image builds to you. If the application is a stateless container, Cloud Run behind the same load balancer removes the instance management and scales to zero. Use regional instance groups across zones, and keep the database in the same region as the instances to avoid cross-region latency and egress charges.
