Amazon S3 Express One Zone is a high-performance, single-Availability Zone storage class purpose-built to deliver consistent single-digit millisecond data access for your most frequently accessed data and latency-sensitive applications. S3 Express One Zone delivers data access speed up to 10x faster and request costs up to 50% lower than S3 Standard. While you have always been able to choose a specific AWS Region to store your S3 data, with S3 Express One Zone you can select a specific AWS Availability Zone within an AWS Region to store your data. You can choose to co-locate your storage and compute resources in the same Availability Zone to further optimize performance, which helps lower compute costs and run workloads faster. With S3 Express One Zone, data is stored in a different bucket type—an S3 directory bucket—which supports hundreds of thousands of requests per second. Additionally, you can use S3 Express One Zone with services such as Amazon SageMaker Model Training, Amazon Athena, Amazon EMR, and AWS Glue Data Catalog to accelerate your machine learning and analytics workloads. With S3 Express One Zone, storage automatically scales up or down based on your consumption and need, and you no longer need to manage multiple storage systems for low-latency workloads.
How it works
Get started by creating an S3 directory bucket in the Availability Zone of your choosing. You can choose to co-locate your storage and Amazon Elastic Compute Cloud (EC2), Amazon Elastic Kubernetes Service (EKS), and Amazon Elastic Container Service (ECS) compute resources to further optimize performance. You can either upload new objects directly into S3 Express One Zone or copy data from other storage classes using the Import button – a fully managed and trackable method of copying existing objects from a general purpose bucket or prefix in the same AWS Region to a directory bucket. Use your directory buckets with artificial intelligence and machine learning (AI/ML) services and applications and open source frameworks such as PyTorch to accelerate performance-critical workloads and reduce overall total cost of ownership (TCO) through lower latency, quicker processing times and lower compute costs, and lower API request costs.

Pinterest is the visual inspiration platform where over 480M people come each month to search, save, and shop the best ideas in the world. Pinterest leverages advanced machine learning models to analyze billions of objects and personalize recommendations for each of its users.
“Machine learning is at the heart of Pinterest and is powered by large scale ML training log collection. To accelerate data ingestion and distribution at Pinterest, we developed MemQ, an ultra-efficient open source PubSub system that powers all our ML training data and leverages Amazon S3 for supercharging data pipelines at 10s of GB/s while staying cost-efficient. During our evaluation of the Amazon S3 Express One Zone storage class with MemQ, we saw latency improvements of over 10x while increasing our data processing transactions per second. Based on this order of magnitude performance improvement, S3 Express One Zone allows us to enable higher velocity data consumption and more frequent experimentations, while significantly reducing infrastructure costs. S3 Express One Zone is creating a paradigm shift making cloud applications more performant, scalable, flexible, and efficient.”
