    10  
    11  Provides an RDS instance resource.  A DB instance is an isolated database
    12  environment in the cloud.  A DB instance can contain multiple user-created
    13  databases.
    14  
    15  ## Example Usage
    16  
    17  ```
    18  resource "alicloud_db_instance" "default" {
    19  	commodity_code = "rds"
    20  	engine = "MySQL"
    21  	engine_version = "5.6"
    22  	db_instance_class = "rds.mysql.t1.small"
    23  	db_instance_storage = "10"
    24  	db_instance_net_type = "Intranet"
    25  }
    26  ```
