Network Architecture Foundation FAQs

Question 1

Does this skill support multi-environment setups?

Accepted Answer

Yes, it includes specific CIDR layouts and DNS naming patterns for Dev, Staging, and Production to ensure environments remain isolated yet peerable if necessary.

Question 2

What is the baseline subnet structure recommended by this skill?

Accepted Answer

The skill recommends at least three tiers: Public (for NAT/LBs), Private (for application workloads with outbound access), and Database (completely isolated with no internet access).

Question 3

Why should I design the network before deploying compute resources?

Accepted Answer

Network foundations like CIDR ranges and subnet layouts harden quickly once services are deployed. Planning first prevents the need for painful, manual migrations when you need to peer VPCs or scale IP addresses later.

Question 4

What is the benefit of using internal DNS zones like .internal?

Accepted Answer

Internal DNS allows you to use consistent connection strings (e.g., db.internal) across all environments, reducing environment-specific code and preventing accidental connections to the wrong database.

Question 5

How can I reduce my cloud networking costs using this skill?

Accepted Answer

It provides logic for starting with a single NAT Gateway and using Gateway Endpoints (like S3) to bypass data processing charges, only scaling to Multi-AZ NAT when justified by your SLA.
