New — v3.0 with streaming & webhooks

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 &amp; rate limits

Per-tenant, per-token, per-endpoint. Prevent runaway spend and noisy neighbors with hierarchical quota budgets you can revise live.

Events &amp; webhooks

React to writes, deletes, and lifecycle events. Ship them to webhooks, Kafka, EventBridge, or Azure Service Bus with delivery guarantees.

Versioning &amp; 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.

PUT/v3/objects/{bucket}/{key}Upload an object (chunked & resumable)
GET/v3/objects/{bucket}/{key}Download or range-fetch an object
POST/v3/objects/{bucket}/{key}:presignMint a scoped presigned URL
DELETE/v3/objects/{bucket}/{key}Remove object (versioned or hard)
GET/v3/objects/{bucket}List with prefix, delimiter, cursor
OpenAPI 3.1gRPC (Buf)Async webhooks

Developer 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

import { StorageClient } from "@rambim/storage"

const storage = new StorageClient({
  endpoint: "https://api.rambim.io",
  auth: { type: "oidc", issuer: process.env.OIDC_ISSUER! },
})

const object = await storage.objects.put({
  bucket: "reports",
  key: "q3-earnings.pdf",
  backend: "azure-blob",
  encryption: { keyId: "kms:prod/finance" },
  body: fileStream,

Architecture

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

Azure Blob Storage
AWS S3 & MinIO
NFS / SMB / NAS
Zero data lock-in

Your bytes remain in your tenant. Cancel and keep every object where it lives.

Stateless brokers

The API layer holds no bulk data — scale horizontally, upgrade in place.

Kubernetes-native

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.

SOC 2ISO 27001HIPAAGDPRDPDP ActFIPS 140-2

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.

MLOps

AI & ML Data Lakes

Feed training pipelines from any bucket. Version datasets, snapshot for reproducibility, and stream shards to distributed workers.

Healthcare

Healthcare Imaging

DICOM-safe object semantics with per-study access policies. Meets HIPAA and India's ABDM interoperability needs.

BFSI

Regulated Enterprises

Keep evidence for the auditor and elasticity for the developer. WORM buckets, legal holds, and immutable versioning.

Media & Ent.

Media Workflows

Range-fetch multi-terabyte masters, mint scoped URLs for editors, and drop transcodes on write with webhooks.

Retail

E-commerce Assets

Millions of product images and videos, cached at the edge, served under your identity. Direct uploads from browsers.

EdTech

Higher Education

Give faculty and students storage governed by SIS roles. Quota-controlled by department, encrypted end-to-end.
