The option Store files in S3 Standard with appropriate access policy addresses a separate condition: static customer attachments must persist despite one AZ failure. S3 Standard redundantly stores objects across multiple AZs. The actual requirement is teams plan backups but have no tested restoration from deleted data. Recommended corrective action: Set up scheduled backups and conduct file/database restore drills. Durability is not a substitute for user-error recovery.

For the alternative failure an EC2 worker has stateful temporary files that can be discarded on crash, the control Use instance store or ephemeral scratch with regeneration logic is relevant: disposable scratch does not require durable multi-AZ storage. Here the evidence instead is teams plan backups but have no tested restoration from deleted data. The selected technical mechanism is Set up scheduled backups and conduct file/database restore drills: durability is not a substitute for user-error recovery.

Mount regional Amazon EFS with AZ mount targets solves a different operational problem where shared POSIX file access must survive replacing EC2 hosts across AZs. EFS supplies shared managed NFS storage. It does not directly address teams plan backups but have no tested restoration from deleted data. The case calls for Set up scheduled backups and conduct file/database restore drills, since durability is not a substitute for user-error recovery.

Use EC2 instance-store NVMe scratch where supported would help if a scratch rendering process requires the lowest local latency and can lose data on termination. Instance store provides physically attached ephemeral storage. That is not the symptom described here: a database on EC2 needs consistent low-latency high random IOPS. The matching response is Use an appropriately provisioned EBS io2 volume with supported provisioned IOPS, because provisioned IOPS block storage targets demanding random operations.

For the alternative failure a throughput-bound sequential scan needs large block volumes more than low latency, the control Evaluate EBS st1 throughput-optimized HDD for eligible sequential workloads is relevant: sT1 is optimized for throughput rather than random small IOPS. Here the evidence instead is a database on EC2 needs consistent low-latency high random IOPS. The selected technical mechanism is Use an appropriately provisioned EBS io2 volume with supported provisioned IOPS: provisioned IOPS block storage targets demanding random operations.

Use EBS gp3 with tuned IOPS and throughput where supported solves a different operational problem where a boot volume requires sustained general-purpose SSD performance. gp3 separates performance provisioning from capacity. It does not directly address a database on EC2 needs consistent low-latency high random IOPS. The case calls for Use an appropriately provisioned EBS io2 volume with supported provisioned IOPS, since provisioned IOPS block storage targets demanding random operations.

For the alternative failure one EC2 instance expects a volume in another AZ to attach, the control Create or restore the EBS volume in the same Availability Zone is relevant: eBS volumes are AZ-scoped block devices.

The competing option Use EC2 instance-store NVMe scratch where supported would be useful when a scratch rendering process requires the lowest local latency and can lose data on termination. Instance store provides physically attached ephemeral storage. The present issue is a throughput-bound sequential scan needs large block volumes more than low latency; it is more directly addressed by Evaluate EBS st1 throughput-optimized HDD for eligible sequential workloads.

Store assets in Amazon S3 with an appropriate delivery layer would help if static images need object URLs and effectively unlimited object scaling. S3 is object storage with scalable API access. That is not the symptom described here: thousands of Linux application hosts need one shared POSIX file tree. The matching response is Use regional Amazon EFS with appropriate performance settings, because eFS provides elastic concurrent NFS access.

For the alternative failure a data lake needs file semantics on top of S3 for distributed compute, the control Use appropriate managed data lake formats and compute rather than assuming S3 offers POSIX writes is relevant: object stores do not behave like mounted POSIX block devices.
