Networking – Intro & Topology Diagrams for OCI and Azure

In this lesson, we introduce the networking layer in both Oracle Cloud Infrastructure and Microsoft Azure.
You'll explore side-by-side topologies showing how virtual networks and subnets are structured in each cloud.
We’ll break down components like Internet Gateways, NAT Gateways, route tables, and security boundaries.
You’ll see how OCI and Azure implement similar ideas using different services and naming conventions.
This foundational knowledge sets the stage for real-world infrastructure deployments.
After understanding the high-level diagrams, we’ll jump into the code.
You’ll review how these network components are written in Terraform and OpenTofu.
We'll walk through modular code for both OCI and Azure, explaining how the topology maps to infrastructure as code.
This is your first hands-on section—get ready to explore, apply, and verify your cloud networking setup.
Let’s build multicloud infrastructure from the ground up—starting with the network!
