On the Instance Management page, select an instance and click Manage in the Actions column to view its basic information and API endpoints.
Basic information
The Instance Details page shows information about the instance, such as the instance ID, billing method, and region.
-
To classify and manage OpenSearch resources using tags, click the Edit icon next to the Tag parameter. For more information, see Tag overview.
-
To add a custom description, click Edit next to the Instance Description parameter.
Standard Edition instances do not support custom large language models (LLMs). The GPU Specifications and GPUs parameters are not required when purchasing a Standard Edition instance, so hyphens (-) are displayed next to these parameters.
API endpoints
API endpoints (also called endpoints) vary by region. To connect to an OpenSearch instance via API or SDK, use the endpoint shown on the Instance Details page.
Choose an endpoint type
Use the internal endpoint when possible. It provides lower latency and higher stability than the public endpoint. Before connecting, ping the internal endpoint to confirm it is reachable.
| Situation | Endpoint to use |
|---|---|
| Your Elastic Compute Service (ECS) instance and the OpenSearch instance are in the same region, use the same network type, and — if both use virtual private clouds (VPCs) — reside in the same VPC. | Internal endpoint |
| Any other situation, including connecting from an on-premises device. | Public endpoint |
Get the endpoint
On the Instance Management page, find the instance, click Manage in the Actions column, and copy the endpoint URL from the Instance Details page.
What's next
Use the endpoint with the OpenSearch API or SDK to access your instance.
