Before use

Q. What is Object Storage used for?

NAVER CLOUD PLATFORM's Object Storage is a file storage service that helps users store and look up data anytime, anywhere. It is used for the following purposes.

  • Storage, sharing and distribution of files: You can store content, which can be then shared with or distributed to other users.
  • Large repositories: You can store mass data in Object Storage.
  • Data backup and long-term retention: You can back up important data and retain it for a long time.

Q. How do I use Object Storage?

Apply for Object Storage from NAVER CLOUD PLATFORM Console to use it.Follow the steps from the Console as below to use Object Storage.

① Choose Object Storage after accessing the Console.

② Apply for the Object Storage service by clicking Apply for use.

③ Create a bucket after accessing the Console.

④ Make use of the bucket by uploading or downloading files to it.

To use Object Storage with API, you should create an API authentication key from Home > My page > Manage authentication key. After getting the API key, read the Object Storage API guide and follow the tutorials to use the service.

Q. What is the difference between Public administration and Permissions?

Public administration allows you to open your buckets or files to users who are not the members of NAVER CLOUD PLATFORM. Permissions for buckets are different from those for files.

  • Make buckets public: Allows users to view the list of objects (files and folders) in the bucket and upload files.
  • Make files public: Allows users to view file information and download files.

Permissions enables you to assign permissions to NAVER CLOUD PLATFORM users. You can use this to grant specific permissions to specified users.

  • Permissions for buckets: List Object, Upload, ACL Lookup, and Edit ACL
  • Permissions for files: Download, ACL Lookup and Edit ACL

Q. Can I use a tool working with S3?

Since Object Storage provides AWS S3 compatible API, you can use any tool that works with S3 in Object Storage.

(Example) Using S3 Browser

① Install S3 Browser: Download the latest version of the software. (

② Run S3 Browser, and go to Menu > Account > Add New Account to set the following.

  • Account Type : S3 Compatible Storage
  • REST Endpoint :
  • Access Key ID : Access key (Enter the API authentication key that you selected when you request Object Storage.
                            To see your authentication key information, go to **My Page > Manage Account > Manage Authentication Key** in NAVER CLOUD PLATFORM’s portal.)
  • Secret Access Key : Secret key (Enter the secret key connected with the API authentication key.)
  • Use secure transfer(SSL/TLS) : Check

③ Check if it is successfully connected on the Task tab.

  • Check if you can create and delete buckets, upload and download files, and create and delete folders.
  • We recommend you to use NAVER CLOUD PLATFORM’s Console or the related APIs in order to grant permissions.

Q. How much does Object Storage cost?

The price plans for Object Storage are basically pay-as-you-go.

Object Storage charges = Data storage charges + charges for API calls + network transmission charges

  • Data storage charges: Changes calculated based on the amount of capacity used to store your data in Object Storage and the storage period.
  • Charges for API calls: Charges for API calls made to view the list of objects, upload and download files, etc.
  • Network transmission charges: Charges for downloading files.

Network transaction fees between Object Storage and CDN+ or Global CDN will not charged.

Q. What is Lifecycle Management?

All data will be used less frequently over time. Therefore, high-utilization data can be stored in high-speed I / O storage, and data that requires long-term storage for compliance and future analysis can be used for low-cost TCO savings.

Naver Cloud Platform's Object Storage provides a high level of I / O speed compared to Archive Storage. Therefore, it provides Lifecycle Management function to store frequently used data in Object Storage and archived data in Archive Storage.

Through schedule-based policy, you can automatically transfer data from Object Storage to Archive Storage to provide a foundation for systematic data management as well as cost reduction.

Q. How do I use it?

Lifecycle Management can be applied and used from the Naver Cloud platform Console. Follow the steps outlined below to try it on your Console.

① Connect to Console and select Object Storage service.

② Click Lifecycle Management in Object Storage to access the dedicated menu.

③ Add the policy by clicking the + Add Life Cycle Policy button.

Q. Is there an extra charge?

There is no additional charge for Lifecycle Management.
