Complete copies of every version get billed separately, multiplying costs.

Open table formats add database consistency and transactions to S3's cheap, durable storage.

Configure part size, concurrency, and queue depth together to maximize S3 upload speed.

Transition charges and hidden fees can overwhelm the savings lifecycle policies promise.

EBS suits single-node workloads while EFS enables multi-node ML training with shared state.

Faster checkpointing patterns preserve GPU utilization when distributed training clusters fail.

Versioning creates hidden storage costs that compound silently until the bill arrives.

Lifecycle rules expire data on schedule; Object Lock prevents deletion before its time.

Portable storage has become essential as most enterprises now run workloads across multiple clouds.

AI workloads demand different storage at each stage, making hybrid architecture a deliberate choice.

Models reason better with POSIX file systems than object storage.
