Your network needs a front-yard house​

Day 8: You tested and validated your network

Today: We build the front door (Application Load Balancer)

Here's the setup:

Trust, but verify​

Days 3-7: You built the entire network infrastructure

Today: We prove it actually works

Here's the situation:

You've built:
✅ VPC with Internet Gateway
✅ Public and private subnets
✅ NAT Gateway
✅ Route Tables
✅ Security Groups

But you haven't actually tested any of it.

What if:

• NAT Gateway isn't running correctly?
• Route tables have the wrong associations?
• Secure Groups are blocking traffic?
• Something is misconfigured?

You'd fund out after deploying your containers (painful debugging)

Solution: Test first, deploy second.

Your network needs smart locks​

Day 6: You built the roads (route tables)

Today: We add the smart locks (Security Groups)

Here's the problem:

Your routing works, traffic can flow.

But there's NO security layer yet.

Right now:

• Anyone can try to connect to your containers
• No firewall rules
• No access control

That's a security issue.

Solution: Security Groups

Your gates need directions​

Day 5: You built the back gate (NAT Gateway)

Today: We build the roads that connect everything

Here's the problem:

You have:

✅ Neighborhood front gate (Internet Gateway)
✅ Back gate (NAT Gateway)
✅ Front yards (public subnets)
✅ Back yards (private subnets)

But nothing is connected yet.

Your back yard needs an exit​

Day 4: You divided your VPC into front yards (public) and back yards (private)

Today: We build the back gate (NAT Gateway)

Your neighborhood needs houses​

Day 1: Your AI agent's first phone call Day 1 ↗
Day 2: Give your AI agent a real-world mission Day 2 ↗
Day 3: You claimed your territory (VPC) Day 3 ↗

Today: We'll build our neighborhood with subnets

Your AI agent needs a home​

Days 1-2: Your AI caller agent ran on your laptop.

Today: We're moving it to the cloud
