-Provisioning on AWS  DNS -> ALB -> Autoscaling -> EC2 -> RDS -> ...
+# The set of these modules for create ALB, WAF, ASG, EC2, R53, IAM, RDS Secrets, S3, EFS, VPC
+
+## ALB
+
+Rules:
+
+- redirect www to non www
+- redirect HTTP to HTTP(S)
+
+## WAF
+
+Rules:
+
+- Managed_Rules_WordPress_Rule_Set
+- Managed_Rules_PHP_Rule_Set
+- Managed_Rules_SQLi_Rule_Set
+- IP_Rate_Based_Rule (`var.ip_rate_limit_reqests_num`)
+- Block_country (`var.country_codes_block`)
+
+## ASG
+
+Autoscaling policy:
+
+- UP/DOWN adding 2 instance or remove one
+- by CPU UP - (75%), DOWN - (50%)
+- ASG 5XX error more 10% and Downscale when less 5%
+
+## EC2
+
+- Placement group
+- SSH keys (RSA and DSA)
+
+## Template
+
+- AMI Amazon Linux 2
+- Instance type - `local.instance_type`
+- Instance type `Spot` - `module.spot-price.spot_price_current_optimal`
+- ENS GP3 20Gb
+
+
+## EFS (NFS)
+
+- Encrypted by (`module.iam.aws_kms_key_arn`)
+
+## IAM
+
+- KMS key
+- SSM, EFS, RDF policy
+
+## S3
+
+- Bucket for ALB logs
+
+## Secrets
+
+Password and login for RDS will be available as ENV variables inside instances:
+
+- `MYSQL_PASSWD`
+- `MYSQL_LOGIN`
+- `MYSQL_DBNAME`
+- `MYSQL_ADDRESS`
+- Password, Login generated automatically and DB name.
+
+## RDS
+
+- Engine `aurora-mysql`, mode `serverless`
+- `scaling_configuration` `min = 1`, `max = 2`
+
+## VPC
+
+Two zones (a and b) and private and public subnets.
+
+
+## Used modules
+
+`git submodule init`
+
+- An easy way to get the best Spot price to control costs. [terraform-aws-ec2-spot-price](https://github.com/fivexl/terraform-aws-ec2-spot-price)
+- Creates S3 bucket on AWS with all (or almost all) features provided by Terraform AWS provider. [terraform-aws-s3-bucket](https://github.com/terraform-aws-modules/terraform-aws-s3-bucket)
