One API for every backend.
Rambim Enterprise Storage APIs give your applications a unified data plane across Azure Blob, AWS S3, MinIO, and on-premise storage — with identity, quotas, and audit built in.

Platform Features
The storage layer your product deserves
Nine capabilities that turn commodity storage into an enterprise-grade data plane.
Multi-backend routing
Route every request to Azure Blob, S3, MinIO, or on-premise storage by header, path, or policy — without changing your application code.
Object · File · Block
A single, well-typed schema for object storage, POSIX file semantics, and block volumes. Migrate between them with policy, not rewrites.
Predictable performance
Regional data planes, connection pooling, and request coalescing deliver sub-10 ms p50 latency under real production load.
Identity-first access
Every call is authenticated through Entra ID, Okta, or any OIDC / SAML source. Fine-grained RBAC and ABAC on containers, prefixes, and objects.
Quotas & rate limits
Per-tenant, per-token, per-endpoint. Prevent runaway spend and noisy neighbors with hierarchical quota budgets you can revise live.
Events & webhooks
React to writes, deletes, and lifecycle events. Ship them to webhooks, Kafka, EventBridge, or Azure Service Bus with delivery guarantees.
Versioning & branches
Immutable object versions with Git-style branches for data. Roll back in seconds, compare snapshots, and gate promotion with policies.
Encryption everywhere
TLS 1.3 in transit, envelope encryption at rest with your KMS or HSM keys. Object-level encryption context for defense in depth.
Developer-first DX
OpenAPI 3.1 & Buf-generated gRPC, typed SDKs for six languages, a Postman workspace, and a browser-based API console.
API Surface
Six domains. One consistent design.
REST, gRPC, and streaming endpoints share a single object model, error envelope, and pagination cursor.
Objects
Multipart, resumable, and range-aware object I/O with etag semantics.
/v3/objects/{bucket}/{key}Upload an object (chunked & resumable)/v3/objects/{bucket}/{key}Download or range-fetch an object/v3/objects/{bucket}/{key}:presignMint a scoped presigned URL/v3/objects/{bucket}/{key}Remove object (versioned or hard)/v3/objects/{bucket}List with prefix, delimiter, cursorDeveloper Experience
Write once. Run against any backend.
Native, typed SDKs mirror the REST surface exactly. Switch the backend header and your code moves from Azure to S3 to on-premise with zero refactoring.
- OpenAPI 3.1 spec & Buf-generated gRPC stubs
- SDKs for TypeScript, Python, Go, Java, .NET, Rust
- Retries, backoff, resumable uploads & streaming built in
- Postman workspace and an in-browser API console

A control plane over your storage — not another silo
Your data stays exactly where it is. Rambim brokers every request with identity, policy, and observability.

Your Storage — Your Tenant
Your bytes remain in your tenant. Cancel and keep every object where it lives.
The API layer holds no bulk data — scale horizontally, upgrade in place.
Ship as Helm chart or managed service. Terraform modules included.
Security & Compliance
Auditable, encrypted, and yours.
Storage APIs are the last surface an attacker touches before your data. We treat every request like it matters — because it does. Zero-trust identity, customer-owned keys, and a hash-chained audit trail are defaults, not upgrades.
Zero-trust identity
Every request presents a short-lived OIDC-issued token. No long-lived secrets, no shared credentials.
Customer-managed keys
Bring your own KMS or HSM. Envelope-encrypted objects with per-tenant key hierarchies.
Tamper-evident audit
Every read, write, and policy change signed and hash-chained. Streams to your SIEM in real time.
Private networking
Deploy behind VNet / VPC. mTLS between planes, IP allowlists, and Private Link out of the box.
Anomaly detection
Baseline access patterns per tenant and token. Alert on exfiltration, credential replay, and drift.
Compliance-ready
Aligned to SOC 2 Type II, ISO 27001, HIPAA, GDPR, and India's DPDP Act. Attestations on request.
Use Cases
Built for real workloads
Teams across regulated and high-scale industries use the Storage APIs as their unified data plane.
AI & ML Data Lakes
Feed training pipelines from any bucket. Version datasets, snapshot for reproducibility, and stream shards to distributed workers.
Healthcare Imaging
DICOM-safe object semantics with per-study access policies. Meets HIPAA and India's ABDM interoperability needs.
Regulated Enterprises
Keep evidence for the auditor and elasticity for the developer. WORM buckets, legal holds, and immutable versioning.
Media Workflows
Range-fetch multi-terabyte masters, mint scoped URLs for editors, and drop transcodes on write with webhooks.
E-commerce Assets
Millions of product images and videos, cached at the edge, served under your identity. Direct uploads from browsers.
Higher Education
Give faculty and students storage governed by SIS roles. Quota-controlled by department, encrypted end-to-end.
