Multi-container endpoints

SageMaker AI multi-container endpoints enable customers to deploy multiple containers, that use different models or frameworks, on a single SageMaker AI endpoint. The containers can be run in a sequence as an inference pipeline, or each container can be accessed individually by using direct invocation to improve endpoint utilization and optimize costs.

For information about invoking the containers in a multi-container endpoint in sequence, see Inference pipelines in Amazon SageMaker AI.

For information about invoking a specific container in a multi-container endpoint, see Invoke a multi-container endpoint with direct invocation

The following policy allows invoke_endpoint requests only when the value of the TargetContainerHostname field matches one of the specified regular expressions.
