HashiCorp's Terraform provider for AWS has launched support for Amazon S3 Express One Zone storage class, a high-performance solution for ultra-low latency and large storage volumes. This new bucket type is designed to deliver single-digit millisecond response times for frequently accessed datasets, making it suitable for compute-intensive big data workloads such as autonomous vehicle data, financial risk modeling, real-time online advertising, and machine-learning training and inference. The Terraform provider supports S3 Express through the existing S3 API, allowing for seamless integration with other AWS services. To set up S3 Express, users can use the new `aws_s3_directory_bucket` resource and create a bucket with a hierarchical namespace, low-latency zonal storage class, and fast-authorization API. The provider also offers improved support for managing resources at scale through Terraform stacks.
