The option Use Amazon EBS attached block storage addresses a separate condition: a single EC2 server needs a locally mounted transactional filesystem. EBS supplies block devices for host filesystems. The actual requirement is a data lake needs file semantics on top of S3 for distributed compute. Recommended corrective action: Use appropriate managed data lake formats and compute rather than assuming S3 offers POSIX writes. Object stores do not behave like mounted POSIX block devices.

For the alternative failure static images need object URLs and effectively unlimited object scaling, the control Store assets in Amazon S3 with an appropriate delivery layer is relevant: s3 is object storage with scalable API access. Here the evidence instead is a data lake needs file semantics on top of S3 for distributed compute. The selected technical mechanism is Use appropriate managed data lake formats and compute rather than assuming S3 offers POSIX writes: object stores do not behave like mounted POSIX block devices.

Use regional Amazon EFS with appropriate performance settings solves a different operational problem where thousands of Linux application hosts need one shared POSIX file tree. EFS provides elastic concurrent NFS access. It does not directly address a data lake needs file semantics on top of S3 for distributed compute. The case calls for Use appropriate managed data lake formats and compute rather than assuming S3 offers POSIX writes, since object stores do not behave like mounted POSIX block devices.

Consider S3 Transfer Acceleration for supported geographically distant transfers would help if a download client must accelerate large uploads from remote geographies. Accelerated endpoints use AWS edge routing toward the bucket. That is not the symptom described here: global viewers fetch the same immutable images with high latency. The matching response is Cache images in Amazon CloudFront near viewers, because edge caching shortens repeated read paths.

For the alternative failure thousands of tiny files cause excessive S3 request overhead for a batch job, the control Coalesce files into appropriately sized columnar objects is relevant: fewer larger objects reduce request and metadata overhead. Here the evidence instead is global viewers fetch the same immutable images with high latency. The selected technical mechanism is Cache images in Amazon CloudFront near viewers: edge caching shortens repeated read paths.

The competing option Use S3 multipart upload with retry of individual parts would be useful when a large object upload often fails near completion and must restart from zero. Multipart retries avoid reuploading successful parts. The present issue is global viewers fetch the same immutable images with high latency; it is more directly addressed by Cache images in Amazon CloudFront near viewers. Edge caching shortens repeated read paths.

For the alternative failure a single prefix is receiving unexpectedly hot request traffic, the control Review request partitioning and scaling guidance instead of assuming one static throughput limit is relevant: s3 automatically scales prefixes but workload design still matters. Here the evidence instead is thousands of tiny files cause excessive S3 request overhead for a batch job. The selected technical mechanism is Coalesce files into appropriately sized columnar objects: fewer larger objects reduce request and metadata overhead.

For the alternative failure a ZFS workload depends on file snapshots and high-throughput low-latency access, the control Evaluate Amazon FSx for OpenZFS with appropriate provisioning is relevant: managed OpenZFS supports ZFS-oriented file workloads.
