This terraform module creates an EC2 Cluster on AWS.
The following resources will be created:
- Elastic File System (EFS)
- Auto Scaling
- Security groups for (ALB/NLB,EC2,EFS)
- IAM roles and policies for the EC2 instances
In addition, you have the option to create:
-
Elastic Load Balancer
- ALB - An external Application Load Balancer
- NLB - An external Network Load Balancer
-
Route 53 (requires ALB)
- URL pointing to a hostname (NLB or ALB hostname)
