DataSync VS Storage Gateway File Gateway

Key Differences:

DataSync	File Gateway
Designed for migration and periodic sync	Designed for ongoing storage access
Point-in-time data movement	Continuous access pattern
No local caching	Local caching for frequent access
Task-based operation	Mount point-based operation
Pay per data transferred	Pay for storage and requests
Multiple storage service support	S3-focused only
Temporary deployment	Permanent infrastructure component

When to Use Each:

Use DataSync when:

• Performing large-scale data migrations

• Need scheduled periodic data transfers

• Moving data between AWS services

• Require automated validation and verification

• Need detailed transfer metrics and logging

Use File Gateway when:

• Requiring continuous access to cloud storage

• Need local caching for performance

• Want transparent S3 integration for applications

• Need file-share protocols (NFS/SMB)

• Implementing hybrid cloud storage architecture

Integration Scenario: They can be used together - DataSync for initial bulk data upload, then File Gateway for ongoing access and operations. This combination provides efficient migration and operational access patterns.
