Hello,
Welcome to Microsoft Q&A,
The error indicates that the subscription has reached the maximum quota limit in Azure Search Service. You currently have 8 out of 8 allowed instances of this tier in your Azure subscription. This means your deployment is failing because there are no available slots for additional services of this type.
- Sign in to the Azure portal, search for "quotas" in your dashboard, and then select the Quotas service.
- In the Quota's Overview page, select Search.
- Set filters so that you can review existing quota for search services in the current subscription. We recommend filtering by usage.
- Find the region and tier that needs more quota and select the Edit pencil icon to begin your request.
- In Quota details, specify the location, tier, and a new limit for your subscription quota. None of the values can be empty. The new limit must be greater than the current limit. If regional capacity is constrained, your request won't be automatically approved. In this scenario, an incident report is generated on your behalf for investigation and resolution.
- Submit the request.
- Monitor notifications in the Azure portal for status updates on the new limit. Most requests are approved within 24 hours.
If you don't want to wait for a quota increase, consider reducing existing Search Service instances:
- Go to Azure Portal → Cognitive Search Service.
- Identify any unused or underutilized instances.
- Delete or downgrade existing Standard2-tier instances.
- Retry your template deployment.
