Deploy and manage public index endpoints

There are a few steps required before you can query an index:

1. Create an IndexEndpoint if needed, or reuse an existing IndexEndpoint.
2. Get the IndexEndpoint ID.
3. Deploy the index to the IndexEndpoint.

Create an IndexEndpoint

gcloud

Before using any of the command data below, make the following replacements:

• INDEX_ENDPOINT_NAME: Display name of the index endpoint.
• LOCATION: The region where you are using Vertex AI.
• PROJECT_ID: Your Google Cloud project ID.

Note: To use a public endpoint, --public-endpoint-enabled must be specified.

Execute the following command:

Linux, macOS, or Cloud Shell

Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

gcloud ai index-endpoints create \
    --display-name=INDEX_ENDPOINT_NAME \
    --public-endpoint-enabled \
    --region=LOCATION \
    --project=PROJECT_ID

Windows (PowerShell)

Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

gcloud ai index-endpoints create `
    --display-name=INDEX_ENDPOINT_NAME `
    --public-endpoint-enabled `
    --region=LOCATION `
    --project=PROJECT_ID

Windows (cmd.exe)

Note: Ensure you have initialized the Google Cloud CLI with authentication and a project by running either gcloud init; or gcloud auth login and gcloud config set project.

gcloud ai index-endpoints create ^
    --display-name=INDEX_ENDPOINT_NAME ^
    --public-endpoint-enabled ^
    --region=LOCATION ^
    --project=PROJECT_ID

REST

Before using any of the request data, make the following replacements:

• INDEX_ENDPOINT_NAME: Display name of the index endpoint.
• LOCATION: The region where you are using Vertex AI.
• PROJECT_ID: Your Google Cloud project ID.
• PROJECT_NUMBER: Your project's automatically generated project number.

Note: To use a public endpoint, the publicEndpointEnabled field must be true.

HTTP method and URL:

POST https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/indexEndpoints

Request JSON body:

{
 "display_name": "INDEX_ENDPOINT_NAME",
 "publicEndpointEnabled": "true"
}

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json, and execute the following command:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/indexEndpoints"

PowerShell (Windows)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json, and execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/indexEndpoints" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/indexEndpoints/INDEX_ENDPOINT_ID/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.aiplatform.v1.CreateIndexEndpointOperationMetadata",

   Go to Vector Search

2. A list of your active indexes is displayed.
3. Select the name of the index you want to deploy. The index details page opens.
4. From the index details page, click Deploy to endpoint. The index deployment panel opens.
5. Enter a display name - this name acts as an ID and can't be updated.
6. From the Endpoint drop-down, select the endpoint you want to deploy this index to. Note: The endpoint is unavailable if the index is already deployed to it.
7. Optional: In the Machine type field, select either standard or high-memory.
8. Optional. Select Enable autoscaling to automatically resize the number of nodes based on the demands of your workloads. The default number of replicas is 2 if autoscaling is disabled.
9. Click Deploy to deploy your index to the endpoint. Note: It takes around 30 minutes to be deployed.

Important: If you use a public endpoint, you are required to use OAuth authentication. In this case, don't specify the deployedIndexAuthConfig, which is used for private endpoint authentication.

Get the index domain name

After the index is deployed, you need the domain name to be able to use the index for an online query. The value is available under publicEndpointDomainName.

curl -H "Content-Type: application/json" -H "Authorization: Bearer `gcloud auth print-access-token`"  ${ENDPOINT}/v1/projects/${PROJECT_ID}/locations/${REGION}/indexEndpoints/${INDEX_ENDPOINT_ID}

Enable autoscaling

Vector Search supports autoscaling, which can automatically resize the number of nodes based on the demands of your workloads. When demand is high, nodes are added to the node pool, which won't exceed the maximum size you designate. When demand is low, the node pool scales back down to a minimum size that you designate. You can check the actual nodes in use and the changes by monitoring the current replicas.

To enable autoscaling, specify the maxReplicaCount and minReplicaCount when you deploy your index:

gcloud

The following example uses the gcloud ai index-endpoints deploy-index command.

Before using any of the command data below, make the following replacements:

• INDEX_ENDPOINT_ID: The ID of the index endpoint.
• DEPLOYED_INDEX_ID: A user specified string to uniquely identify the deployed index. It must start with a letter and contain only letters, numbers or underscores. See DeployedIndex.id for format guidelines.
• DEPLOYED_INDEX_NAME: Display name of the deployed index.
• INDEX_ID: The ID of the index.
• MIN_REPLICA_COUNT: Minimum number of machine replicas the deployed index will be always deployed on. If specified, the value must be equal to or larger than 1.
• MAX_REPLICA_COUNT: Maximum number of machine replicas the deployed index could be deployed on.
• LOCATION: The region where you are using Vertex AI.
• PROJECT_ID: Your Google Cloud project ID.

Console

You can only enable autoscaling from the console during index deployment.

1. In the Vertex AI section of the Google Cloud console, go to the Deploy and Use section. Select Vector Search

   Go to Vector Search

2. A list of your active indexes is displayed.
3. Select the name of the index you want to deploy. The index details page opens.
4. From the index details page, click Deploy to endpoint. The index deployment panel opens.
5. Enter a display name - this name acts as an ID and can't be updated.
6. From the Endpoint drop-down, select the endpoint you want to deploy this index to. Note: The endpoint is unavailable if the index is already deployed to it.
7. Optional: In the Machine type field, select either standard or high-memory.
8. Optional. Select Enable autoscaling to automatically resize the number of nodes based on the demands of your workloads. The default number of replicas is 2 if autoscaling is disabled.

• If both minReplicaCount and maxReplicaCount are not set, they are set to 2 by default.
• If only maxReplicaCount is set, minReplicaCount is set to 2 by default.
• If only minReplicaCount is set, maxReplicaCount is set to equal minReplicaCount.

Note: Google recommends that your DeployedIndex uses at least two replicas per shard. To do so, set minReplicaCount to 2.

Mutate a DeployedIndex

You can use the MutateDeployedIndex API to update the deployment resources (for example, minReplicaCount and maxReplicaCount) of an already deployed index.

• Users aren't allowed to change the machineType after the index is deployed.
• If maxReplicaCount isn't specified in the request, the DeployedIndex keeps using the existing maxReplicaCount.

Deployment settings that impact performance

The following deployment settings can affect latency, availability, and cost when using Vector Search. This guidance applies to most cases. However, always experiment with your configurations to make sure that they work for your use case.

Setting	Performance impact
Machine type	The hardware selection has a direct interaction with the shard size selected. Depending on shard choices you specified at index creation time, each machine type offers a tradeoff between performance and cost. Reference the pricing page to determine the hardware available and pricing. In general, performance increases in the following order: E2 standard E2 highmem N1 standard N2D standard
Minimum replica count	minReplicaCount reserves a minimum capacity for availability and latency to ensure that the system doesn't have cold start issues when traffic scales up quickly from low levels. If you have workloads that drop to low levels and then quickly increase to higher levels, consider setting minReplicaCount to a number that can accommodate the initial bursts of traffic.
Maximum replica count	maxReplicaCount primarily lets you control usage cost. You can choose to prevent increasing costs beyond a certain threshold, with the tradeoff of allowing increased latency and reducing availability.

List IndexEndpoints

    index_endpoint.delete(force=force)

Console

Use these instructions to delete an index endpoint.

1. In the Vertex AI section of the Google Cloud console, go to the Deploy and Use section. Select Vector Search

   Go to Vector Search

2. On the top of the page, select the Index endpoint tab.
3. All of the existing index endpoints are displayed.
4. Click the options menu that is in the same row as the index you want to delete and select Delete.
5. A confirmation screen opens. Click Delete. Your index endpoint is now deleted.

Note: It takes 10 to 20 minutes for Google backend jobs to clean up the deployment. You can't reuse the DeployedIndex ID until after the deployment is cleaned up.
