F5 Public Cloud Solutions > A&O Toolchain: BIG-IP HA in Public Cloud with Terraform (Agility Labs 2023) > 3. App Deployment with Application Services 3 Extension (AS3) Source | Edit on
3.1. Lab Scenario¶
3.1.1. Network Diagram¶
Two AWS VPCs are connected to an AWS Transit Gateway, which routes traffic between the VPCs. The app VPC contains two application server instances (each in a different availability zone). The hub VPC contains two BIG-IP VE instances (each in a different availability zone).
Only one of the BIG-IP instances and the two application servers are needed in this lab module.

3.1.2. Infrastructure Target State¶
You will deploy AS3 configurations for the following:
- Two HTTP applications using AWS autodiscovery
- Two HTTPS applications configured to use HTTP/2
- Update the two HTTPS applications to use ECDSA certificates
You will also examine an application configuration from BIG-IP qkview snapshot, and then convert it into an AS3 declaration.
