The option Apply noncurrent-version lifecycle policies with required recovery retention addresses a separate condition: historical noncurrent versions are retained forever after enabling versioning. Versioned storage accumulates noncurrent bytes without expiration. The actual requirement is a program spends heavily on millions of small S3 GET calls from repeated hot content. Recommended corrective action: Put CloudFront cache in front of eligible immutable objects. Edge caching can reduce origin request counts.

Evaluate S3 Requester Pays for the approved access arrangement would help if a bucket is accessed mostly by a requester in another account who should pay data transfer/request charges. Requester Pays transfers eligible request billing to the requester. That is not the symptom described here: a program spends heavily on millions of small S3 GET calls from repeated hot content. The matching response is Put CloudFront cache in front of eligible immutable objects, because edge caching can reduce origin request counts.

For the alternative failure data from one Region is copied daily to another for analysis even though consumers could read in-region, the control Move analytics near the data or limit replicated subsets is relevant: cross-region data transfer can dominate storage charges. Here the evidence instead is a program spends heavily on millions of small S3 GET calls from repeated hot content. The selected technical mechanism is Put CloudFront cache in front of eligible immutable objects: edge caching can reduce origin request counts.

For the alternative failure a mission-critical database requires minute-scale recovery despite slow archive restore, the control Keep an operational standby and use backup primarily for point-in-time recovery is relevant: archive-only recovery cannot satisfy stringent RTO. Here the evidence instead is every backup is a full database copy stored forever despite a 30-day policy. The selected technical mechanism is Use managed incremental/snapshot backups and bounded retention: incremental backup mechanisms reduce duplicate stored changes.

Enforce snapshot lifecycle retention and remove superseded backups solves a different operational problem where a small test environment creates hourly snapshots and never deletes them. Excess orphan snapshots inflate storage spend. It does not directly address every backup is a full database copy stored forever despite a 30-day policy. The case calls for Use managed incremental/snapshot backups and bounded retention, since incremental backup mechanisms reduce duplicate stored changes.

The competing option Use suitable archive-class storage with tested retrieval timing would be useful when long-term compliance data must be retrievable only occasionally. Archive tiers reduce cost when retrieval is infrequent. The present issue is every backup is a full database copy stored forever despite a 30-day policy; it is more directly addressed by Use managed incremental/snapshot backups and bounded retention. Incremental backup mechanisms reduce duplicate stored changes.

For the alternative failure a company stores redundant full copies of logs in three unrelated buckets, the control Consolidate retention into governed tiered destinations without violating isolation needs is relevant: avoidable duplicate bytes increase storage cost.

For the alternative failure a snapshot collection references deleted EC2 instances but remains retained, the control Audit and expire orphaned EBS snapshots according to recovery policy is relevant: snapshots incur ongoing storage charges until removed. Here the evidence instead is a general-purpose SSD volume is oversized merely to obtain more performance. The selected technical mechanism is Migrate to gp3 and provision IOPS/throughput separately within limits: gp3 performance can be specified independently of GB.

Use io2 only where latency/IOPS demands justify its price solves a different operational problem where a database requires consistent very high random IOPS. High-performance SSD costs more than general purpose. It does not directly address a general-purpose SSD volume is oversized merely to obtain more performance. The case calls for Migrate to gp3 and provision IOPS/throughput separately within limits, since gp3 performance can be specified independently of GB.

The competing option Reduce future allocations using measured capacity and appropriate migration design would be useful when an overprovisioned EBS volume has 80 percent unused capacity. Right sizing avoids paying for unused provisioned GB.

For the alternative failure a database requires consistent very high random IOPS, the control Use io2 only where latency/IOPS demands justify its price is relevant: high-performance SSD costs more than general purpose. Here the evidence instead is a cold HDD archival scan workload only needs infrequent sequential throughput. The selected technical mechanism is Evaluate EBS sc1 for eligible cold sequential workloads: cold HDD tiers have lower cost with limited IOPS.
