Lfs: S3 Account
Since "LFS S3 Account" isn't a single official product name but rather a concept involving the configuration of Git LFS to use an S3 bucket as its storage backend, I have written a comprehensive guide on this topic below.
Error: "403 Forbidden" on S3 Bucket
- Cause: The IAM user lacks
s3:PutObject permission.
- Fix: Attach the full S3 read/write policy. Ensure bucket ACLs don't block the IAM user.
12. Legal/compliance notes
- Consider data residency requirements when selecting S3 region.
- Apply appropriate encryption and retention policies for regulated data.
7. Performance and cost
- Performance factors:
- S3 request latency and regional placement relative to developer location.
- Number of small objects vs. larger single objects — S3 handles large objects well, but many tiny objects can add overhead.
- Parallel multipart uploads for large LFS objects.
- Cost considerations:
- Storage class and lifecycle transitions (Standard, Intelligent-Tiering, Infrequent Access, Glacier).
- PUT/GET request costs; consider batching or minimizing repeated downloads.
- Data transfer costs for cross-region or internet egress.
- Recommendations:
- Use region close to users/CI runners.
- Set lifecycle policies to transition rarely-accessed blobs.
- Consider caching frequently accessed LFS objects in a CDN or artifact cache for CI.
