Three-Tier Web App

A classic three-tier cloud architecture pattern using CloudBlocks.

Architecture Overview

Internet → Gateway (Application Gateway)
              ↓
         Public Subnet
              ↓
         Compute (VM / Container App)
              ↓
         Private Subnet
           ↓        ↓
     Database    Storage
     (Managed)  (Blob Storage)

Components

Layer	Category	Block Type	Subnet	Description
Frontend	Edge	Gateway	Public	Application Gateway / Load Balancer
Application	Compute	Compute	Public	VM or Container App instances
Data	Data	Database	Private	Managed database server
Data	Data	Storage	Private	Blob storage for static assets

How to Build in CloudBlocks

1. Create a Region Plate (VNet)
2. Add a Public Subnet Plate inside the Region Plate
3. Add a Private Subnet Plate inside the Region Plate
4. Place a Gateway block on the Public Subnet
5. Place a Compute block on the Public Subnet
6. Place a Database block on the Private Subnet
7. Place a Storage block on the Private Subnet
8. Connect: Internet → Gateway → Compute → Database
9. Connect: Compute → Storage
10. Run Validate to confirm the architecture is valid

Generate Infrastructure Code

After validation, click Generate to export Terraform (or Bicep/Pulumi) code for this architecture. The generated code will be committed to your connected GitHub repository.
