Introduction
In this article, we can learn how to store data in Huawei Cloud Storage with AppGallery Connect. Cloud Storage provides users to store high volumes of data such as images, audio, and videos generated by your users securely and economically with direct device access.
What is Cloud Storage?
Cloud Storage is the process of storing digital data in an online space that extends multiple servers and locations and is maintained by a hosting company. It delivers on-demand with just-in-time capacity and costs and avoids purchasing and managing users' own data storage infrastructure.

For example, if you have saved any data such as ID Cards, Certificates, or any Personal documents in your local computer or device if it cashes the entire data will vanish. So, if you saved the data in Cloud Storage, then you can upload, view, download, and delete at any time. You don’t need to worry about safety and security.
