• Terraform cloudformation template to create a AWS infrastructure for the architecture shown below.
• Create a VPC with private and public subnets on all availability zones.
• Create a NAT, IGW, route table for all the subnets
• Create S3 buckets for magento static and media files.
• Create a CDN for s3 buckets and create a route53 alias A record.
• Create a ALB, Listener target group and route52 alias A record.
• Create a Redis Elasticache accessible inside the VPC.
• Create an Elastic search accessible inside the VPC.
• Create a IAM policy for EC2 to access the media and static s3 bucket
• Create a mysql RDS instance in private subnets.
• Create a jump server in the public subnet to access resources in private subnet.
• Create required security groups for all the resources.
• Pass on created infra details to downstream process
• Packer will build an AMI with all the magento production ready code and update the created infra details. New AMI details will be passed on to deploy-app
• Deploy app will create a launch config and autoscaling group.
• Created the ASG policy and attached the autoscaling group to the target group created earlier.

• Average monthly budget depends on the size of instance we select. For t3a.medium instance average monthly cost comes around €250.

Install terraform and packer

This terraform template assumes you already have hosted zone added in route53 and have the required ssl certificate for domain and cdn(in us-east-1 region)

In pre-build-custom-ami directory

cd pre-build-custom-ami

create env.json file

{
  "aws_access_key": "",
  "aws_secret_key": "",
  "aws_region": ""
}

And run

chmod +x build.sh
./build.sh

In initial-aws-setup

cd ../initial-aws-setup
ssh-keygen -f magentokey
