High performance object storage overview

A high-performance, scalable and secure storage space


Upload your static files (videos, images, web files) to an unlimited space. Use them from your application or make them accessible on the web via our S3 API.

This storage space can be scaled up as your project grows, with no need to plan for it in advance. It’s the perfect place for storing performance-intensive data. It can meet the requirements of big data and artificial intelligence (AI), or simply help you get the most out of your data.

Adapt your application effortlessly

Update your configuration (the endpoint and credentials) while keeping the same application code and tools.


Create a bucket

# aws --endpoint-url https://s3.<public cloud region>.cloud.ovh.net s3 mb s3://test1

List your buckets

# aws s3 ls

Push your files as objects in a bucket

# aws s3 cp /etc/magic s3://test1

There’s no need to plan ahead for additional storage space to meet your growing needs. With object storage, store all types of files without being blocked by a potential lack of disk space.


As a business you need to have constant access to your collaborative tools. OVHcloud provides you with collaborative solutions based on a dedicated and resilient infrastructure, monitored by our teams 24/7. 

Public or private

Containers and their objects are only accessible after authentication. To make objects publicly available, you can open up access to them on the web without authentication.


With object storage, you can sort your storage into categories by adding tags to your objects or buckets. Each tag is associated with a key-value pair.

Temporary URL

You can use temporary URLs to provide read or write access to an object, for a specific period of time. Once the time period has elapsed, the URL will no longer be valid.

Large storage space

You can use up to 100 buckets per S3 account for object storage.

Access Control List (ACL) management

You can configure specific access permissions for objects and containers, by both user and access method.

S3 credential generation

To configure a tool on the S3 API, you can generate credentials that are specific to this use. Simply change the endpoints in the application by using these credentials to get this compatibility.

Large objects

Object Storage allows you to store objects of all sizes, from small to very large, with no size limit. For example, you can store files containing several terabytes of data.


Using this mechanism managed via code in a web browser, you can provide access to objects from other domain names. This separates a website's code from its static objects.


The object metadata automatically includes an MD5 signature, in order to ensure the integrity of your transferred object.

DNS usage

You can redirect to a container in your Object Storage by configuring a specific record in your domain name’s DNS zone.

Public Cloud Pricing

Object Storage Billing

Object storage is charged per GB, per hour. The displayed price indicates the cost of a full month of storage. Outgoing traffic from objects is also charged per GB.

The advantages of object storage

Object storage offers a number of advantages, the main one being reduced costs as your data grows. Your data is stored on one or more servers sized to accommodate terabytes or even petabytes of information, while optimising operational costs. The environment is also designed to adapt to changing needs, without needing to overhaul the infrastructure or the way it runs. 


What SLA does OVHcloud offer for accessing the Object Storage service?

The SLA guarantees 99.9% monthly availability for accessing the Object Storage service. For further information, please refer to the Terms & conditions.

What SLA does OVHcloud offer for data resilience on the Object Storage service?

The data resilience rate is 100% for the Object Storage service. For further information, please refer to the Terms & conditions.

File system vs Object Storage: what’s the difference?

There are many differences. The two most important differences are the fact that Object Storage is used for static data only, and that the solution offers unlimited storage space.

Object Storage vs block storage: what’s the difference?

The differences between Object Storage and Block Storage are mainly the access modes and volume limitations. The Block Storage service provides storage spaces that are sized as required and attached to an instance. These spaces are managed by the instance’s operating system. Object Storage provides unlimited space that is managed directly by your application.

How do I access and/or manipulate data in Object Storage?

There are several ways of manipulating the data stored on Object Storage. To integrate this management directly into your application, you can use one of the available SDKs. You can also directly use a client that is available on the market.

What is the maximum authorised size for an object?

An object cannot exceed 5TB.

What is the limit for the volume of data that can be stored on Object Storage?

Virtually, there is no limit. In other words, OVHcloud manages the service, so that there is always space available.

What is Object Storage?

It is a technology that offers an online storage service. It is accessible via API, provides users with an unlimited amount of space to store data, and the Object Storage cluster is managed by the cloud provider. You can push all types of data into an Object Storage service.

How does Object Storage work?

An Object Storage service works in a cluster with a large number of storage servers sharing algorithms to ensure data resilience. The service places and indexes data depending on which spaces are available. A cluster can be enlarged at any time.
