EnglishWhat is Ceph.io?
Updated
Ceph.io is the official home of Ceph, an open-source distributed storage system. If you want to understand what Ceph is, download it, read its documentation, or contribute to its code, ceph.io is the entry point. It is a project and documentation site, not a hosted storage service you sign up for.
What Ceph actually is
Ceph is a distributed storage system designed to evolve with data. According to the site, it provides a unified storage service with object, block, and file interfaces from a single cluster built from commodity hardware components. That single sentence carries most of what makes Ceph distinctive:
- One cluster, three interfaces. Instead of running separate systems for object storage, block devices, and shared file systems, Ceph exposes all three from the same cluster.
- Commodity hardware. It is built to run on standard components rather than specialized storage appliances.
- Distributed and scalable. The site describes it as "reliable and scalable storage designed for any organization."
- Open source. Ceph is fully open source, so you can study, modify, and contribute to the code.
What you can do on ceph.io
The homepage organizes its audience into a few clear paths:
| Goal | Where the site points you |
|---|---|
| Get started with Ceph | "Get Started with Ceph" |
| Deploy or manage a cluster | "Deploy Ceph now" links, plus getting started and documentation |
| Read the docs | Documentation |
| Work on the code | Browse the code, understand the architecture, contribute |
So the site serves two broad groups: operators who want to acquire Ceph and run a cluster, and developers who want to read, modify, or contribute to the project.
Who this is for
Ceph.io is relevant if you are:
- Evaluating distributed storage for an organization and want to know what Ceph offers.
- Planning to deploy or manage a Ceph cluster and need acquisition links and documentation.
- A developer interested in the architecture or in contributing to a project "used at scale across the world."
It is less useful if you are looking for a managed, sign-up-and-use storage product. The site presents Ceph as software you deploy and manage, not as a hosted service.
Where to start
- If you are new to Ceph, start with the "Get Started with Ceph" path to understand the system.
- If you already intend to run it, follow the "Deploy or manage a Ceph cluster" links to acquire Ceph and deploy a cluster.
- If you want to work on the project itself, go to the developer section to browse the code, understand the architecture, and contribute.
The site does not publish pricing on the pages reviewed here, so treat ceph.io as the project's information and download hub rather than a commercial storefront.
