Starting today, you can attach Amazon S3 Access Points to your Amazon FSx for OpenZFS file systems to access your file data as if it were in Amazon Simple Storage Service (Amazon S3). With this new capability, your data in FSx for OpenZFS is accessible for use with a broad range of Amazon Web Services (AWS) services and applications for artificial intelligence, machine learning (ML), and analytics that work with S3. Your file data continues to reside in your FSx for OpenZFS file system.

Organizations store hundreds of exabytes of file data on premises and want to move this data to AWS for greater agility, reliability, security, scalability, and reduced costs. Once their file data is in AWS, organizations often want to do even more with it. For example, they want to use their enterprise data to augment generative AI applications and build and train machine learning models with the broad spectrum of AWS generative AI and machine learning services. They also want the flexibility to use their file data with new AWS applications. However, many AWS data analytics services and applications are built to work with data stored in Amazon S3 as data lakes. After migration, they can use tools that work with Amazon S3 as their data source. Previously, this required data pipelines to copy data between Amazon FSx for OpenZFS file systems and Amazon S3 buckets.

Amazon S3 Access Points attached to FSx for OpenZFS file systems remove data movement and copying requirements by maintaining unified access through both file protocols and Amazon S3 API operations. You can read and write file data using S3 object operations including GetObject, PutObject, and ListObjectsV2. You can attach hundreds of access points to a file system, with each S3 access point configured with application-specific permissions. These access points support the same granular permissions controls as S3 access points that attach to S3 buckets, including AWS Identity and Access Management (IAM) access point policies, Block Public Access, and network origin controls such as restricting access to your Virtual Private Cloud (VPC). Because your data continues to reside in your FSx for OpenZFS file system, you continue to access your data using Network File System (NFS) and benefit from existing data management capabilities.

You can use your file data in Amazon FSx for OpenZFS file systems to power generative AI applications with Amazon Bedrock for Retrieval Augmented Generation (RAG) workflows, train ML models with Amazon SageMaker, and run analytics or business intelligence (BI) with Amazon Athena and AWS Glue as if the data were in S3, using the S3 API. You can also generate insights using open source tools such as Apache Spark and Apache Hive, without moving or refactoring your data.

To get started
You can create and attach an S3 Access Point to your Amazon FSx for OpenZFS file system using the Amazon FSx console, the AWS Command Line Interface (AWS CLI), or the AWS SDK.

To start, you can follow the steps in the Amazon FSx for OpenZFS file system documentation page to create the file system, then, using the Amazon FSx console, go to Actions and select Create S3 access point. Leave the standard configuration and then create.

To monitor the creation progress, you can go to the Amazon FSx console.

Once available, choose the name of the new S3 access point and review the access point summary. This summary includes an automatically generated alias that works anywhere you would normally use S3 bucket names.

Using the bucket-style alias, you can access the FSx data directly through S3 API operations.

• List objects using the ListObjectsV2 API

• Get files using the GetObject API

• Write data using the PutObject API

The data continues to be accessible via NFS.

Beyond accessing your FSx data through the S3 API, you can work with your data using the broad range of AI, ML, and analytics services that work with data in S3. For example, I built an Amazon Bedrock Knowledge Base using PDFs containing airline customer service information from my travel support application repository, WhatsApp-Powered RAG Travel Support Agent: Elevating Customer Experience with PostgreSQL Knowledge Retrieval, as the data source.

To create the Amazon Bedrock Knowledge Base, I followed the connection steps in Connect to Amazon S3 for your knowledge base user guide. I chose Amazon S3 as the data source, entered my S3 access point alias as the S3 source, then configured and created the knowledge base.

Once the knowledge base is synchronized, I can see all documents and the Document source as S3.

Finally, I ran queries against the knowledge base and verified that it successfully used the file data from my Amazon FSx for OpenZFS file system to provide contextual answers, demonstrating seamless integration without data movement.

Things to know
Integration and access control – Amazon S3 Access Points for Amazon FSx for OpenZFS file systems support standard S3 API operations (such as GetObject, ListObjectsV2, PutObject) through the S3 endpoint, with granular access controls through AWS Identity and Access Management (IAM) permissions and file system user authentication. Your S3 Access Point includes an automatically generated access point alias for data access using S3 bucket names, and public access is blocked by default for Amazon FSx resources.

Data management – Your data stays in your Amazon FSx for OpenZFS file system while becoming accessible as if it were in Amazon S3, eliminating the need for data movement or copies, with file data remaining accessible through NFS file protocols.

Performance – Amazon S3 Access Points for Amazon FSx for OpenZFS file systems deliver first-byte latency in the tens of milliseconds range, consistent with S3 bucket access. Performance scales with your Amazon FSx file system’s provisioned throughput, with maximum throughput determined by your underlying FSx file system configuration.

Pricing – You’re billed by Amazon S3 for the requests and data transfer costs through your S3 Access Point, in addition to your standard Amazon FSx charges. Learn more on the Amazon FSx for OpenZFS pricing page.

You can get started today using the Amazon FSx console, AWS CLI, or AWS SDK to attach Amazon S3 Access Points to your Amazon FSx for OpenZFS file systems. The feature is available in the following AWS Regions: US East (N. Virginia, Ohio), US West (Oregon), Europe (Frankfurt, Ireland, Stockholm), and Asia Pacific (Hong Kong, Singapore, Sydney, Tokyo).
