Whenever you create a flow, the Amazon Bedrock console creates a getting started flow for you. The flow includes with a Flow input node, a Prompt node and a Flow output node. When you run the flow, you enter a topic for the flow which uses the prompt node to summarize the topic. Before you can run the flows, you need to set the model for the prompt.
To create a flow, you provide a name and description for the flow. By default Amazon Bedrock creates a service role with the proper permissions. Optionally, you can specify an existing service role.
Amazon Bedrock encrypts your data at rest. By default, Amazon Bedrock encrypts this data using an AWS managed key. Optionally, you can encrypt the flow execution data using a customer managed key. For more information, see Encryption of Amazon Bedrock Flows resources.
After you finish with the getting started flow, or if you don't need it, you can continue building your flow. We recommend that you read How Amazon Bedrock Flows works to familiarize yourself with concepts and terms in Amazon Bedrock Flows and to learn about the types of nodes that are available to you. For more information, see Design a flow in Amazon Bedrock.
