# Creating an RDS for SQL Server Developer Edition DB instance
<a name="sqlserver-dev-edition.creating-instance"></a>

Launching Developer Edition instance on RDS for SQL Server follows a two-step process: first create a CEV with `create-custom-db-engine-version`, Once your custom engine version is in the available state, you can create Amazon RDS database instances using the CEV.

**Key differences for Developer Edition instance creation**


| Parameter | Developer Edition | 
| --- | --- | 
| `--engine` | sqlserver-dev-ee | 
| `--engine-version` | Custom engine version (e.g., 16.00.4215.2.cev-dev-ss2022-cu21) | 
| `--license-model` | bring-your-own-license |

To create a SQL Server Developer Edition DB instance, use the [create-db-instance](https://docs.amazonaws.cn//cli/latest/reference/rds/create-db-instance.html) command with the following parameters:

The following options are required:
+ `--db-instance-identifier` 
+ `--db-instance-class` 
+ `--engine` – `sqlserver-dev-ee`
+ `--region`

**Examples:**

For Linux, macOS, or Unix:

```
aws rds create-db-instance \
--db-instance-identifier my-dev-sqlserver \
--db-instance-class db.m6i.xlarge \
--engine sqlserver-dev-ee \
--engine-version {{16.00.4215.2.my-dev-cev}} \
--allocated-storage 200 \
--master-username admin \
--master-user-password {{changeThisPassword}} \
--license-model bring-your-own-license \
--no-multi-az \
--vpc-security-group-ids {{sg-xxxxxxxxx}} \
--db-subnet-group-name {{my-db-subnet-group}} \
--backup-retention-period 7 \
--region {{us-west-2}}
```

For Windows:

```
aws rds create-db-instance ^
--db-instance-identifier my-dev-sqlserver ^
--db-instance-class db.m6i.xlarge ^
--engine sqlserver-dev-ee ^
--engine-version {{16.00.4215.2.cev-dev-ss2022-cu21}} ^
--allocated-storage 200 ^
--master-username admin ^
--master-user-password {{master_user_password}} ^
--license-model bring-your-own-license ^
--no-multi-az ^
--vpc-security-group-ids {{sg-xxxxxxxxx}} ^
--db-subnet-group-name {{my-db-subnet-group}} ^
--backup-retention-period 7 ^
--region us-west-2
```
