What is IBM Cloud Object Storage
IBM Cloud Object Storage is an S3-compatible object storage service for storing and retrieving unstructured data such as backups, media assets, logs, and data lake content. It targets IT teams and developers that need durable storage with lifecycle controls, encryption, and multi-region options within IBM Cloud. The service supports multiple storage classes and integrates with IBM Cloud IAM and related IBM Cloud services. It also offers deployment options aligned to IBM’s object storage technology lineage, including configurations designed for higher resiliency and geographic distribution.
S3-compatible API support
The service provides an S3-compatible API, which helps teams reuse existing tooling and SDKs built for S3-style object storage. This can reduce migration effort for applications that already use common object storage patterns. It also supports standard object operations and bucket-level configuration expected in this category.
Security and access controls
IBM Cloud Object Storage integrates with IBM Cloud Identity and Access Management for role-based access control and service-to-service authorization. It supports encryption features and policy-based controls that are typical requirements for regulated workloads. These capabilities help centralize governance across storage resources in IBM Cloud.
Storage classes and lifecycle policies
The product offers multiple storage classes to align cost and access frequency, such as frequent access and archival-style tiers. Lifecycle rules can automate transitions and retention behaviors to manage long-term storage growth. This supports common use cases like backups, compliance retention, and log/data lake storage.
IBM Cloud ecosystem dependence
While S3 compatibility helps portability, many operational workflows (IAM, monitoring, billing, networking patterns) align most naturally with IBM Cloud services. Organizations standardized on other cloud platforms may need additional integration work for identity, observability, and automation. This can increase operational complexity in multi-cloud environments.
Feature parity varies by region
As with many global cloud storage services, available regions and specific capabilities can vary by geography and deployment option. Teams with strict data residency requirements may need to validate which resiliency options, endpoints, and storage classes are available in their target locations. This can affect architecture choices for multi-region applications.
Not a VPC core product
Although it is used within VPC-based architectures, the product’s core function is object storage rather than virtual networking. Customers seeking a single product that primarily delivers VPC capabilities will need to use IBM Cloud VPC and related networking services alongside it. This separation can require additional design and configuration effort.
Plan & Pricing
Usage-based (Standard plan) — Pay-as-you-go (representative official rates shown for the us-east region):
Pricing model: Pay-as-you-go Free tier (monthly allowances, 12 months): Smart Tier storage up to 5 GB; 2,000 Class A requests; 20,000 Class B requests; 10 GB data retrieval; 5 GB public outbound egress. Example costs (official ordering/pricing table, region: us-east):
- Capacity (Standard): $0.0230 per GB
- Capacity (Flex): $0.0094 per GB
- Capacity (Cold Vault): $0.0063 per GB
- Capacity (Vault): $0.0125 per GB
- Public outbound bandwidth: $0.0900 per GB
- Class A operations: $0.0052 per 1,000 requests
- Class B operations: $0.0042 per 10,000 requests
- Data retrieval (Flex / Cold Vault / Vault examples): $0.0303 / $0.0523 / $0.0105 per GB (see official table for region variations)
- Archive storage: $0.0010 per GB; Archive restore: ~$0.0209 per GB (region-dependent)
Notes: Rates vary by region and by storage class; the ordering/pricing page contains per-region tables and Flex/Archive specifics. (See IBM official pricing table.)
One-Rate plan (IBM "One-Rate" pricing — all-inclusive, tiered by total monthly stored capacity):
| Plan | Price | Key features & notes |
|---|---|---|
| One-Rate (2PB+) | $10 per TB per month (USD) | All-inclusive per-GB rate (storage, API requests, retrieval, egress). Applies when total One-Rate storage >= 2 PB; rate applies to entire One-Rate footprint. (Announced Jan 8, 2026.) |
| One-Rate (promotional level) | As low as $12 per TB per month (USD) — promotional | IBM published promotional pricing (sign-up deadlines and regional differences apply); One-Rate includes built-in allowances for egress and API operations; full One-Rate tier table is published on IBM pricing pages and is region-specific. |
If you need the full One-Rate tier breakouts (all capacity bands and region-specific rates), IBM’s official Cloud Object Storage pricing page / ordering page lists the complete tables by region.
