In our Auto-Scaling WordPress CloudFormation, you will be able to use horizontally scalable WordPress architecture. New instances are automatically added to manage your server CPU increased load over 70%. Once the load decrease to 30% it will start removing newly added instances to save the cost. This way we make your site highly scalable and available for new users. Services used in our Auto-Scaling WordPress CloudFormation are EC2, ALB, EFS, and RDS.
