S3-compatible object storage

The same S3 API as Amazon. Your existing tools and SDKs work with no code changes — you pay only for volume.

Who needs object storage

The most common teams and tasks where S3 storage pays off right away

  • Developers and product teams

    User files, images, video, logs — your app writes to a bucket via the S3 SDK (boto3, aws-sdk-js and others) with no code changes.

  • DevOps and administrators

    Offsite backups of servers and databases: Veeam pushes copies to our S3 as a repository; restic, Duplicati and rclone all work. Versioning protects against accidental deletion and ransomware.

  • Businesses leaving AWS or storing data in the EU

    The same API — without lock-in to the Amazon ecosystem, with a predictable bill and locations in Ukraine and the EU. Ideal for data-residency requirements.

  • AI/ML teams

    Datasets and model artifacts next to Cloud GPU — traffic between storage and GPU instances inside the platform is free.

Works with the tools you already use

Compatible with popular S3 clients, SDKs, and backup systems

  • aws cli
  • rclone
  • boto3 (Python)
  • aws-sdk (JS/Go/Java/PHP)
  • s3cmd
  • Cyberduck
  • WinSCP

One line — and your first file is in storage
# Upload a file to a bucket with aws cli
aws s3 cp backup.tar.gz s3://my-bucket/ \
  --endpoint-url https://s3.ua-central-1.ocplanet.cloud

Storage is built on Ceph RGW — the industry standard for S3-compatible storage. Multipart upload, presigned URLs, versioning, ACLs and access policies are supported.

What you get

Standard S3 with no surprises — and a predictable bill

  • S3 API with no surprises

    Standard S3 operations: buckets, multipart upload for large files, presigned URLs for temporary access, permission management via keys and policies.

  • 99.95% reliability

    Data is replicated across nodes of a Ceph cluster — a disk or node failure is invisible to you.

  • Scaling with no administration

    No need to plan a “disk size”: storage grows with your data, and you pay for the actual volume.

  • Fast access over HTTPS

    Every object is available by URL. Public buckets and a custom domain — serve site static and media straight from storage.

  • Versioning and delete protection

    Enable versioning on a bucket — previous versions are kept, so accidental deletion or ransomware won't destroy data irreversibly.

  • Locations: Ukraine, Poland, Netherlands

    Keep data closer to users or meet residency requirements. Geo-replicating backups to a second location is a few lines in rclone.

What it's for

Typical scenarios where object storage is the best choice

  • Backups and archives

    Offsite copies of VMs, databases and file servers. Object storage is cheaper than block disks and not tied to any server.

  • Site static and media

    Images, video, JS/CSS, downloadable files — offload your web server and keep content separate from compute.

  • Data for AI/ML and analytics

    Datasets, model checkpoints, a data lake — with access from OneCloudPlanet Cloud GPU and Kubernetes clusters.

  • Logs and documents

    Centralized storage of logs and documents with retention (lifecycle) policies.

1 TB — $0.04 per day. Everything else — $0

Only storage is billed. Outbound traffic and PUT/GET requests are free, with no limits.

1 TB — $0.04 per day. Everything else — $0
What OneCloudPlanet AWS S3 Standard
Storage, 1 TB ≈ $0.04/day (≈ $1.33/mo) ≈ $0.77/day (≈ $23/mo)
Outbound traffic Free, no limits ≈ $90 per 1 TB
PUT/GET requests Free $5 per 1M PUT + $0.4 per 1M GET
Bill at month end Predictable A surprise

Billing is daily — you pay only for the days data was actually stored. Delete the data and billing stops that same day.

Example: 500 GB of backups — about $0.02 per day (≈ $0.65/mo), with no charge for restoring when you need the backup.

Rate: $0.0013 per GB/mo. Payment in UAH at the NBU rate. AWS figures are shown for comparison and may change.

Estimate your volume Create a bucket

How to start — 3 steps

From sign-up to your first object in storage — in minutes

  1. Sign up

    Register in the OneCloudPlanet panel — all you need is an email.

  2. Create a bucket and keys

    Create a bucket and generate a key pair (Access Key / Secret Key) in the console.

  3. Connect with an S3 client

    Point your S3 client or SDK at the endpoint s3.ua-central-1.ocplanet.cloud (Ukraine location) — and get to work.

Move without changing code

Thanks to API compatibility, migration comes down to syncing data and swapping the endpoint

Example synchronization with rclone
# Sync a bucket from AWS S3 to OneCloudPlanet storage
rclone sync aws-s3:my-bucket ocp-s3:my-bucket --progress
