]Key Takeaways
- 1S3, Blob Storage, and Cloud Storage are functionally equivalent object stores.
- 2Storage tiers map across providers: hot, cool/infrequent, and archive classes exist everywhere.
- 3Lifecycle policies automate tier transitions on all three platforms.
- 4Redundancy options range from single-zone to cross-region replication.
- 5Pricing models differ but all charge for storage, operations, and egress.
Frequently Asked Questions
What is the GCP equivalent of AWS S3?
Google Cloud Storage (GCS) is the equivalent of AWS S3. Both are object storage services supporting buckets, objects, versioning, lifecycle policies, and fine-grained access controls.
How do storage tiers compare across providers?
AWS has S3 Standard, Intelligent-Tiering, Standard-IA, One Zone-IA, Glacier, and Deep Archive. Azure has Hot, Cool, Cold, and Archive tiers. GCP has Standard, Nearline, Coldline, and Archive classes.
Which cloud provider offers the cheapest archive storage?
Pricing varies by region, but all three providers offer archive storage at similar price points around $1-2/TB/month. AWS Glacier Deep Archive, Azure Archive, and GCP Archive are competitive. Retrieval costs and times differ significantly.
Can I replicate storage across cloud providers?
Cross-cloud replication is not natively supported. You would need third-party tools or custom solutions using cloud functions triggered by storage events to replicate objects between providers.
What is the maximum object size across providers?
AWS S3 supports up to 5 TB per object, Azure Blob supports up to 190.7 TB for block blobs, and GCP Cloud Storage supports up to 5 TB per object. All support multipart uploads for large files.
