AWS has decided to discontinue AWS Proton, with support ending on October 7, 2026. New customers will not be able to sign up after October 7, 2025, but existing customers can continue to use the service until October 7, 2026.For more information, see [AWS Proton Service Deprecation and Migration Guide](https://docs.aws.amazon.com/proton/latest/userguide/proton-end-of-support.html).

# CreateEnvironmentTemplate
<a name="API_CreateEnvironmentTemplate"></a>

Create an environment template for AWS Proton. For more information, see [Environment Templates](https://docs.aws.amazon.com/proton/latest/userguide/ag-templates.html) in the * AWS Proton User Guide*.

You can create an environment template in one of the two following ways:
+ Register and publish a *standard* environment template that instructs AWS Proton to deploy and manage environment infrastructure.
+ Register and publish a *customer managed* environment template that connects AWS Proton to your existing provisioned infrastructure that you manage. AWS Proton *doesn't* manage your existing provisioned infrastructure. To create an environment template for customer provisioned and managed infrastructure, include the `provisioning` parameter and set the value to `CUSTOMER_MANAGED`. For more information, see [Register and publish an environment template](https://docs.aws.amazon.com/proton/latest/userguide/template-create.html) in the * AWS Proton User Guide*.
