Deploy and integrate an Amazon Bedrock agent into your application

When you first create an Amazon Bedrock agent, you have a working draft version (DRAFT) and a test alias (TSTALIASID) that points to the working draft version. When you make changes to your agent, the changes apply to the working draft. You iterate on your working draft until you're satisfied with the behavior of your agent. Then, you can set up your agent for deployment and integration into your application by creating aliases of your agent.

To deploy your agent, you must create an alias. During alias creation, Amazon Bedrock creates a version of your agent automatically. The alias points to this newly created version. Alternatively, you can point the alias to a previously created version of your agent. Then, you configure your application to make API calls to that alias.

A version is a snapshot that preserves the resource as it exists at the time it was created. You can continue to modify the working draft and create new aliases (and consequently, versions) of your agent as necessary. In Amazon Bedrock, you create a new version of your agent by creating an alias that points to the new version by default. Amazon Bedrock creates versions in numerical order, starting from 1.

Versions are immutable because they act as a snapshot of your agent at the time you created it. To make updates to an agent in production, you must create a new version and set up your application to make calls to the alias that points to that version.

With aliases, you can switch efficiently between different versions of your agent without requiring the application to keep track of the version. For example, you can change an alias to point to a previous version of your agent if there are changes that you need to revert quickly.

To deploy your agent

1. Create an alias and version of your agent. Select the tab corresponding to your method of choice and follow the steps.

   Console

   To create an alias (and optionally a new version)

   1. Sign in to the AWS Management Console using an IAM role with Amazon Bedrock permissions, and open the Amazon Bedrock console at https://console.aws.amazon.com/bedrock/.

   2. Select Agents from the left navigation pane. Then, choose an agent in the Agents section.

   3. In the Aliases section, choose Create.

   4. Enter a unique Alias name and provide an optional Description.

   5. Under Associate a version, choose one of the following options:

      • To create a new version, choose Create a new version and to associate it to this alias.

      • To use an existing version, choose Use an existing version to associate this alias. From the dropdown menu, choose the version that you want to associate the alias to.

   6. Under Select throughput, select one of the following options:

      • To let your agent run model inference at the rates set for your account, select On-demand (ODT). For more information, see Quotas for Amazon Bedrock.

      • To let your agent run model inference at an increased rate using a Provisioned Throughput that you previously purchased for the model, select Provisioned Throughput (PT) and then select a provisioned model. For more information, see Increase model invocation capacity with Provisioned Throughput in Amazon Bedrock.

   7. Select Create alias.

   API

   To create an alias for an agent, send a CreateAgentAlias request (see link for request and response formats and field details) with an Agents for Amazon Bedrock build-time endpoint.

   The following fields are required:

   Field	Use case
   agentId	To specify the ID of the agent for which to create an alias.
   agentName	To specify a name for the alias.

   The following fields are optional:

   Field	Use case
   description	To provide a description of the alias.
   routingConfiguration	To specify a version to associate the alias with (leave blank to create a new version) and a Provisioned Throughput to associate with the alias.
   clientToken	Identifier to ensure the API request completes only once.
   tags	To associate tags with the alias.

   See code examples

2. Deploy your agent by setting up your application to make an InvokeAgent request (see link for request and response formats and field details) with an Agents for Amazon Bedrock runtime endpoint. In the agentAliasId field, specify the ID of the alias pointing to the version of the agent that you want to use.
