AWS Cloud Quest Lab 11: Auto Scaling Walkthrough (High Availability Badge!)
1That's a fantastic resource for tackling the AWS Cloud Quest High Availability Concepts Level 11: Auto Scaling challenge!
This comprehensive tutorial breaks down the mission into four essential steps to successfully implement a resilient and highly available web application:
AWS Auto Scaling Challenge: Core Steps
To complete the mission, you'll need to focus on these key components:
Create a Launch Template: This defines the configuration for the instances your Auto Scaling Group (ASG) will launch. You must specify the AMI, instance type, security group, and any necessary user data (like an installation script for your web application).
Configure the Auto Scaling Group (ASG): This is the heart of the solution. You will link your Launch Template here and define your capacity requirements:
Minimum Capacity: The smallest number of running instances allowed.
Maximum Capacity: The largest number of running instances allowed.
Desired Capacity: The number of instances you want running under normal load.
Define Scaling Policies: Implement Dynamic Scaling to automatically adjust capacity based on demand. For this challenge, you will typically define a policy (e.g., a Target Tracking Policy) to launch new instances when a metric like CPU Utilization exceeds a specific threshold (e.g., 70%).
Verification: Test your setup by generating load or simply observing the ASG in the EC2 console to ensure it correctly launches and terminates instances based on your policies.
