# Test 6 — two-AZ Application Load Balancer baseline

**Result:** PASS  
**Verified:** 6 Aug 2026, 18:59 SGT  
**AWS account:** 427617722186  
**Region:** Europe (Ireland), `eu-west-1`

## Objective

Prove the deployed steady-state load-balancing baseline: one Application Load Balancer spans two Availability Zones, forwards HTTP/80 to one healthy application target in each zone, and returns successful public HTTP responses.

## Live evidence captured

- Application Load Balancer: `eg334s-team2-alb-alb`
- Scheme and state: internet-facing, active
- Availability Zones: `eu-west-1a` and `eu-west-1b`
- Listener: HTTP/80 forwarding 100% to target group `eg334s-Targe-OBEMJZNXDJEL`
- Web Node 1: `i-04d4025fda0bb37b4`, `eu-west-1a`, healthy
- Web Node 2: `i-081a925b57241ed06`, `eu-west-1b`, healthy
- Resource map: one listener, one rule, one target group and two healthy targets
- CloudShell verification at `2026-08-06 18:59:58 SGT`: six of six requests returned HTTP 200, with observed request times between 0.005 and 0.015 seconds

## Recording

[Open the genuine AWS-console Test 6 recording](../../assets/video/06-alb-two-az-baseline.mp4)

The concise recording retains the authenticated AWS console, target health, ALB configuration, network/resource mapping and timestamped CloudShell output. Navigation and loading time were removed; no state-changing operation was performed.

## Claim boundary

This test verifies the two-AZ steady-state load-balancing baseline. It does not inject a target failure, prove Auto Scaling replacement, claim a complete Availability Zone outage, or claim zero-interruption failover. Those are separate controlled actions with their own evidence.
