VPC
A virtual private cloud is a logically isolated virtual network provisioned within a cloud provider's shared infrastructure.
Amazon Web Services in Action, Third Edition: An in-depth guide to AWS
Amazon VPC is a logically isolated virtual network for resources in AWS.
- How it is used
- Provides the network boundary for separating public-facing web components from private application and database resources.
- How deep it goes
- Works through an addressed three-subnet design and CloudFormation-based setup, then examines Lambda access and failover constraints.
- Examples
- Uses a public-proxy/private-backend web application and a VPN-connected enterprise application with a restricted SQL database.
- What you can do after
- Build it from scratch with CloudFormation by defining a VPC and public and private subnets for a web application.

Google Anthos in Action
A virtual private cloud (VPC) is an isolated virtual network that provides address ranges, routing, and connectivity for cloud resources.
- How it is used
- Deploys Anthos resources into an isolated cloud network and establishes the foundation for cluster and hybrid connectivity.
- How deep it goes
- Explains topology choices, layered controls, and hybrid connectivity, but stops short of detailed VPC configuration procedures.
- Examples
- Uses single, shared, and multiple VPC architectures plus Interconnect, VPN, and public-internet connectivity scenarios.
- What you can do after
- Operate/configure a VPC topology and select layered security and hybrid-connectivity mechanisms for an Anthos deployment.
Effective Platform Engineering
A virtual private cloud is an isolated logical network within a public cloud that contains configurable address space, subnets, routing, and connectivity controls.
- How it is used
- Provides the network foundation for EKS clusters, service connectivity, address allocation, ingress, and controlled transit between cloud networks.
- How deep it goes
- Descends through subnet roles, CIDR allocation, naming, transit connections, and a cost-versus-resilience NAT decision.
- Examples
- Uses sandbox and production CIDRs, three-availability-zone subnet tables, cluster-matched names, and a simplified single-NAT EKS layout.
- What you can do after
- Operate/configure dedicated, regionally allocated VPCs that support EKS clusters and predictable platform connectivity.
Secure APIs
A virtual private cloud is an isolated virtual network environment provided within a cloud platform.
- How it is used
- Uses VPCs to segment cloud resources and limit communication between network environments.
- How deep it goes
- Explains isolation, peering, subnets, ACLs, and security groups, but stops short of provider configuration steps.
- Examples
- Uses an API gateway and bastion server in a DMZ while protecting internal APIs and databases in private subnets.
- What you can do after
- Operate/configure network segmentation by isolating resources, controlling subnet traffic, and exposing only tested API endpoints.
