• What have you done?

  provision IAC on AWS with [ Terrafrom, Packer, Ansible] for Wordpress using ECS and RDS

• How did you run your project?

  1. First run Packer with Ansible to create Golden image of EC2 Wordpress
  2. Run Terrafrom to launch and release service.

• What are the components interacting with each other?

  1. Ansible interacting between Packer and Terrafrom for this topology.

• What problems did you encounter?

  1. no previous experience on Terrafrom and Packer, so I took courses for both tool and based on that I created the IaC for this repo.

• How would you have done things to have the best HA/automated architecture?

  • Share with us any ideas you have in mind to improve this kind of infrastructure.

    if the final goal to use Wordpress as static site, I prefer to convert the wordpress to static website using plugin or script, then upload it to S3

    If the WordPress will be used as main website or all the operations, I will create auto scale group with two node behand load balancer with EFS between nodes. and maybe if required creating lambda function with event bridge to to advance health-check and based on the result it will take action to guaranty the availability

Tomorrow we want to put this project into production. What would be your advice and choices to achieve that?

1. For the high avaliablty ECS will automatically recover unhealthy containers to ensure from desired number of containers.
2. monitoring: by using newrelic to monitor the app health and performance without complex configration, and for the logs cloudwatch.
3. Database should be Aroura Mysql DB.
4. Add EFS for shared media.

To apply the infrasture follow the below command

#Make sure to update variables.tf
cd Terrafrom
terraform init
terraform fmt . 
terraform validate
terraform plan
terraform apply --auto-approve

cd WP
packer init .
packer build .
#Make to to update var -> variables.pkr.hcl
