Terraform Advanced (GCP) with CI/CD — Lesson 2: Advanced GCP Networking, Shared VPC, and Service Deployment

Lesson Overview

This lesson focuses on Advanced GCP Networking, Shared VPC, and Service Deployment and its role in the wider engineering advanced Google Cloud infrastructure with Terraform, reusable modules, organization controls, secure state, CI/CD promotion, policy checks, and operational validation workflow.

Learners work with the actual design choices, dependencies, controls, and failure modes that distinguish this topic from a generic Terraform exercise.

Technical Scope

VPCs, subnets, secondary ranges, routes, and firewall rules
Shared VPC host and service projects
Private access, NAT, load balancing, and DNS
Managed services, dependencies, and regional design

Instructor Demonstration

Provision a shared VPC pattern and attach an application project.

Applied Workshop

Design private egress and service connectivity for a regional workload.

Translate the scenario into configuration, access, state, pipeline, or module decisions.
Implement the change in a controlled workspace or repository.
Capture the plan, logs, outputs, policy results, and post-change checks.
Explain one safer or more maintainable alternative and its trade-off.

Validation Standard

Network ownership, IP ranges, firewall intent, and cross-project permissions are correct.

The intended target, identity, environment, and state boundary are confirmed.
The plan or execution evidence contains no unexplained destructive action.
Security, reliability, maintainability, and operational ownership are reviewed.
The final result can be reproduced from version-controlled inputs.

Failure Analysis

Fix overlapping CIDRs, attachment permissions, routing, NAT, DNS, and service-agent access.

Learners isolate the smallest verified cause, correct it, rerun the relevant validation step, and record the preventive action in the course improvement log.
