# EUCCOST03-BP02 Use a self-service portal to request your ITSM
<a name="euccost03-bp02"></a>

 Instead of enabling self-service capabilities for your users, use a self-service portal to allow users to request resources, or enable workflow-based request for EUC resources with your ITSM. This gives you better control and limits the exposure to unforeseen cost increases. 

 **Level of risk exposed if this best practice is not established:** Low 

## Implementation guidance
<a name="implementation-guidance-83"></a>

 Consider implementing a self-service portal to request WorkSpaces or changes to your existing WorkSpaces, like running mode, bundle, or storage. A self-service portal can allow your users to provision and terminate their EUC services as required. For an example for Amazon WorkSpaces, see [Creating a self-service portal for Amazon WorkSpaces end users](https://aws.amazon.com/blogs/desktop-and-application-streaming/creating-a-self-service-portal-for-amazon-workspaces-end-users/).  

 Additionally, consider using your ITSM solution to enable workflow-based requests for new WorkSpaces or changes to existing WorkSpaces, like running mode, bundle, or storage. For examples of integrating with ServiceNow, see [How to enable self-service Amazon WorkSpaces by using Service Catalog Connector for ServiceNow](https://aws.amazon.com/blogs/mt/how-to-enable-self-service-amazon-workspaces-by-using-aws-service-catalog-connector-for-servicenow/) and [Managing Amazon WorkSpaces by integrating Service Catalog with ServiceNow](https://aws.amazon.com/blogs/mt/managing-amazon-workspaces-by-integrating-aws-service-catalog-with-servicenow/).
