Cloud Network Architecture
Design how cloud resources communicate with each other, the internet, offices, and other environments. Proven engineering baselines with zero-downtime execution.
Common Challenges & Technical Drivers
- Complex, unmanageable point-to-point VPC peering connections creating routing sprawl.
- IP address CIDR collisions between cloud environments and on-premise networks.
- Databases and internal services accidentally exposed to public internet subnets.
- Lack of network flow log visibility making unauthorized connection attempts undetectable.
What Is Included (In-Scope Deliverables)
- Multi-VPC network topology design with centralized Transit Gateway routing.
- Private link endpoint configuration ensuring cloud service traffic never traverses the public internet.
- Route table segmentation, network access control lists (NACLs), and firewall rules.
- Automated VPC Flow Log aggregation to CloudWatch or central SIEM for traffic analysis.
Scope Boundaries & Transparent Exclusions
- Third-party cloud data transfer, NAT gateway, and Direct Connect physical link costs.
- Physical telco carrier circuit installation and on-premise router cabling.
- Purchasing public IPv4 address blocks from registries.
- Application-level layer-7 proxy debugging unrelated to network routing.
Tangible Engineering Deliverables
- Production Terraform networking modules provisioning VPCs, subnets, and routing tables.
- Comprehensive network topology diagram illustrating private links, transit gateways, and CIDR blocks.
- VPC Flow Log analysis configuration and automated unauthorized traffic alerting rules.
- Network disaster recovery runbook detailing secondary region failover routing.

Frequently Asked Questions
Transit Gateway acts as a central cloud router in a hub-and-spoke topology, scaling to hundreds of VPCs without the n*(n-1)/2 complexity of mesh peering.
