How to access object storage using OpenStack CLI on 3Engines Cloud[🔗](#how-to-access-object-storage-using-openstack-cli-on-brand-name "Permalink to this headline")
=====================================================================================================================================================================

Cloud computing offers the ability to handle large chunks of data, directly on the remote server. OpenStack module [Swift](https://docs.openstack.org/swift/latest/) was created expressly to enable access to unstructured data that can grow without bounds, with the following design goals in mind :

> * durability,
> * scalability,
> * concurrency across the entire data set,
> * all while keeping the API simple.

**Swift** is installed as an independent module but on the syntax level, it is used through the parameters of **openstack** command.

-------------------------------------------------------------

No. 1 **Hosting**

You need a 3Engines Cloud hosting account, available at <https://portal.3Engines.com/>. If you want to follow up with articles about object storage on Horizon, you will this link too: <https://horizon.3Engines.com>.

No. 2 **Install or activate openstack command**

To be able to connect to the cloud, **openstack** command must be operational. If not installed already, use article [How to install OpenStackClient for Linux on 3Engines Cloud](How-to-install-OpenStackClient-for-Linux-on-3Engines-Cloud.html.md)

No. 3 **Authenticate to OpenStack using application credentials**

Then you have to authenticate your account to the cloud. The usual way is to activate **openstack** command using an RC file for on- or two-factor
authentication. That will not work in case of Swift module. It is authenticated with application credentials, as explained in article

[How to generate or use Application Credentials via CLI on 3Engines Cloud](../cloud/How-to-generate-or-use-Application-Credentials-via-CLI-on-3Engines-Cloud.html.md).

No. 4 **Familiarity with object storage on** 3Engines Cloud **OpenStack**

This article is explaining the basics, using the Horizon interface:

[How to use Object Storage on 3Engines Cloud](../s3/How-to-use-Object-Storage-on-3Engines-Cloud.html.md).

Swift can be understood as the CLI tool for accessing object storage under OpenStack.

No. 5 **Python installed**

The following articles contain sections on how to install Python:
