AutoScaling for EC2 instance with Nodejs Application

Question

Hi All,

We have EC2 instance where we deployed nodeJS code on it. Now we are planning to implement autoscaling on it for high availability.

We are having two weeks sprint and every two weeks code will be deployed to EC2 instance.

As part of autoscaling we will create launch template. How to make sure launch template will be updated with latest AMI which has latest deployments.

Regards,
Rajesh B

Answer

You can store the latest AMI ID in the SSM Parameter Store as a parameter.
And, in the launch template, use the parameter to use the latest AMI ID in your deployments automatically.

Using SSM Parameter store will additionally allow you to keep track of versions of AMI IDs
