Cloud DevOps starts with networking, not CI/CD.

Most beginners jump directly into pipelines without understanding how networks actually work in production.
In real-world DevOps, bad networking design causes more outages than bad code.

In this video, I teach GCP Networking for DevOps from zero to production mindset, explaining every concept clearly and then connecting it with industry best practices used in real environments.

This is a core foundational video of the GCP DevOps 2026 series.

What You’ll Learn in This Video
Core Networking Terminologies (Crystal Clear)

* What is VPC
* What are Subnets
* What are IP Ranges and CIDR Blocks
* What is a Firewall
* What is Cloud NAT and why it’s used in private networks

CIDR Block Explained
* 10.0.0.0 as the starting IP
* What /24 subnet mask actually means
* How CIDR controls network size

Production Best Practices: Why Industry uses /16 VPCs
Hidden GCP Detail: The 4 Reserved IPs You CAN'T Use
Stateful vs. Stateless Firewalls: Which one does GCP use?
IAM vs. Firewalls: Identity Security vs. Network Security

Industry Reality (Most Important Lesson)
Creating networks manually from the Google Console is NOT industry practice.

Industry Best Practice:
* Use Infrastructure as Code (IaC)
* Terraform
* Version controlled
* Reproducible
* Auditable
* Safe for teams
* This mindset is what separates real DevOps engineers from console-clickers.

Who Should Watch This Video
DevOps beginners, cloud engineers, students learning GCP, AWS or Azure engineers moving to GCP, and anyone who wants to understand real production-grade cloud networking.

By the end of this video, you will understand GCP networking not as theory, but as a production system.
