# Overview

Cloud Scale [Stratus](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/introduction) is Catalyst's robust and powerful storage solution. You can store data of any format in the form of [Objects](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/objects/introduction/) in containers called [Buckets](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/buckets/name-bucket/). Each Bucket and every individual object in the bucket has a secure [Object URL](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/objects/introduction/#object-url) and [Bucket URL](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/buckets/create-bucket/#bucket-url). You can perform upload and download operations on objects and even provide [custom permissions](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/stratus-permissions/#custom-permissions) for each object.

The following table contains the list of all the Catalyst SDKs that can be used to perform Stratus operations through code.
