Azure Blob Storage
Pros
- + Four cost-optimized access tiers with fully published per-GB and per-operation prices
- + Mature redundancy ladder (LRS through RA-GZRS) with 11 nines claimed durability on LRS
- + Deep Azure integration: Entra ID auth, Private Link, lifecycle management, immutable storage
- + Reserved capacity discounts up to roughly a third on committed storage
- + Global footprint with EU, US, and APAC data residency plus sovereign clouds
Cons
- - No native S3 API — S3-designed tooling needs a third-party proxy
- - Egress, retrieval, and early-deletion fees often dwarf the capacity cost
- - Portal, RBAC, and account-kind surface area is a real learning curve
- - Cool/Cold/Archive tiers carry lower availability targets (99%) and minimum retention periods
- - SLA is 99.9% with capped service credits, not an availability guarantee
Google Cloud Storage
Pros
- + Per-GiB-hour pricing published per class and location, prorated per second — no commitment required
- + Four storage classes put cold bytes as low as about $0.0012/GB-month (Archive)
- + Credit-backed SLA: 99.95% multi/dual-region Standard with 10–50% credits on miss
- + Real S3 interoperability (XML API, HMAC keys, V4 signing) plus a documented migration path
- + Always Free tier (5 GB-months, 50k Class B ops, 100 GB egress in US regions) can host a small real workload
Cons
- - Egress at $0.12/GiB (Premium) makes read-heavy serving expensive without a CDN in front
- - Cold classes carry minimum storage durations and retrieval fees — wrong class choices cost more than Standard
- - Many pricing dimensions (classes, placement, network tiers, operation classes) make forecasting hard
- - IAM and lifecycle configuration is a real learning curve and a common source of misconfiguration
