App Load Balancer + Auto Scaling Group example

On Subdir app-load-balancer-ec2/ an Application Load Balancer + Auto Scaling Group has been used to create a Highly Available application. Which uses Launch Templates to auto scale EC2 instances.

Auto Scaling is triggered by CloudWatch Events depending on CPU usage:

• Over 60% CPU usage, increases instances.
• Under 10% CPU usage, decreases instances.

Amount of Availability Zones and Subnets to deploy the app will be easily defined by variable subnetsCount.

Todo infrastructure ideas:

• A static website hosted in S3 and available to public.
• A high availability (multi Availability Zone) app with Auto Scaling Group of EC2 instances.
• A 3 tier architecture app: web -> backend -> database
• A serverless app
• A replicated MongoDB atlas cloud.
• Make a Bastion
