ChaosSearch, Cloudera, Colorfront, and Pinterest are among customers and partners using Amazon S3 Express One Zone

At AWS re:Invent, Amazon Web Services, Inc. (AWS), an, Inc. company (NASDAQ: AMZN), today announced the general availability of Amazon Simple Storage Service (Amazon S3) Express One Zone, a new high-performance, single-zone Amazon S3 storage class purpose-built to deliver consistent, single-digit millisecond data access for customers’ most latency-sensitive applications. Amazon S3 Express One Zone is the lowest latency cloud object storage available, with data access speed up to 10 times faster and request costs up to 50% lower than Amazon S3 Standard, from any AWS Availability Zone within an AWS Region. For the most demanding workloads, customers can choose to collocate their Amazon S3 Express One Zone data in the same AWS Availability Zone as their compute resources, optimizing compute performance and costs while increasing data processing speed. Amazon S3 Express One Zone is the most performant storage class for request-intensive operations such as machine learning (ML) training and inference, interactive analytics, and media content creation. With Amazon S3 Express One Zone, customers can scale their storage up or down as needed and work with the Amazon S3 APIs they use today. To get started with Amazon S3 Express One Zone, visit

Since its launch 17 years ago, Amazon S3 is the most popular cloud storage service, with millions of customers around the world across all industries and use cases. With industry-leading durability, availability, security, and scalability, Amazon S3 holds more than 350 trillion objects and averages more than 100 million requests per second. Offering a wide range of storage classes, Amazon S3 delivers the best performance at the lowest cost for frequent, infrequent, and archive data-access patterns for virtually any workload. However, emerging use cases, such as ML training and inference, interactive analytics, financial model simulations, real-time advertising, and media content creation, can write and access data millions of times per minute and require consistent, single-digit millisecond response times to meet performance needs. For example, artificial intelligence (AI) and ML model training often requires millions of images and lines of text to be processed in minutes, and data access speed is critical to achieve the highest compute efficiency. In order to reduce storage latency, application run time, and compute costs for performance-critical applications, customers move their most frequently accessed data from Amazon S3 to custom caching solutions. However, this increases complexity, adds operational burden, and requires application modifications because customers must maintain additional storage infrastructure with multiple sets of APIs. This also leads to idle compute time because the compute infrastructure must run while data is copied into the instance, which can increase costs and create inefficiencies.

Amazon S3 Express One Zone is a new, high-performance storage class that delivers the fastest data access speed and highest performance of any cloud object storage for customers’ most latency-sensitive applications. By replicating and storing data on purpose-built hardware and software, Amazon S3 Express One Zone provides up to 10 times faster access speed than Amazon S3 Standard, resulting in accelerated data processing. To further increase access speed and support millions of requests per minute, Amazon S3 Express One Zone stores data in a new bucket type—an Amazon S3 directory bucket. Customers have always been able to choose a specific AWS Region to store their Amazon S3 data. Now, within an AWS Region, customers can choose to collocate their Amazon S3 Express One Zone data in the same AWS Availability Zone as their compute resources for their most demanding workloads, which helps them lower compute costs and run workloads faster. Amazon S3 Express One Zone allows performance-critical applications, such as query-intensive analytics, to achieve single-digit millisecond data access speed with high durability and availability, while reducing request costs by up to 50% compared to Amazon S3 Standard, and reducing compute costs by up to 60%. For example, data analysts often query petabytes of data, and the speed of processing data is important to make timely business decisions. With Amazon S3 Express One Zone, data lake queries complete up to four times faster because data access speed is up to 10 times faster than Amazon S3 Standard, decreasing the workload time for analytics, so data analysts can derive insights and make decisions quicker. Amazon S3 Express One Zone enables customers to scale their storage up or down, and they no longer need to manage multiple storage systems for low latency workloads because their applications access data through the same Amazon S3 APIs used today.

“Millions of customers rely on Amazon S3 for everything from low-cost archival storage to petabyte-scale data lakes, and they want to expand their use to support their most performance-intensive applications where every millisecond counts,” said James Kirschner, general manager of Amazon S3 at AWS. “Amazon S3 Express One Zone delivers the fastest data access speed for the most latency-sensitive applications and enables customers to make millions of requests per minute for their highly accessed datasets, while also reducing request and compute costs.”

With just a few clicks, customers can create a new Amazon S3 directory bucket and either upload new objects directly into the Amazon S3 directory bucket they created or copy objects from existing datasets in other Amazon S3 storage classes using Amazon S3 Batch Operations in the AWS Management Console. Amazon S3 Express One Zone supports Amazon S3 features, including Mountpoint for Amazon S3, Amazon S3 Server-Side Encryption, and Amazon S3 Block Public Access, as well as AWS services, such as Amazon EMR, Amazon Redshift, Amazon SageMaker, and Amazon Bedrock. Amazon S3 Express One Zone is generally available in the US East (N. Virginia), US West (Oregon), Europe (Stockholm), and Asia Pacific (Tokyo), with availability in additional AWS Regions coming soon.
