Object Storage overview

Available in Classic and VPC

Object Storage refers to a service that provides a file storage space for users to store and explore the data they want, anytime and anywhere.

Object Storage features

Object Storage provides the following features:

• Ensuring data integrity and resilience: data durability and resiliency are guaranteed using data encryption over HTTPS, multiple layers of security equipment, and systems designed with a focus on data loss prevention.
• Storing large amounts of data: business agility and flexibility can be enhanced by expanding the storage space from the unit of GB to PB, depending on the business size. In addition, you can store business data without a prior contract.
• Compatible with external tools: you can use NAVER Cloud Platform's console or connect your server and Object Storage with the RESTful API. The API provided is compatible with Amazon S3, allowing you to manage your storage with common tools leveraging Amazon S3.
• Excellent data search: a unique identifier and metadata are given when storing data, enabling you to search for data quickly within a categorized structure.
• Using appropriate storage for each data lifecycle: you can reduce total cost of ownership (TCO) by moving data that is not frequently used due to the expiration of a certain lifecycle to a lower-cost storage.

You can have your questions answered quickly by referring to the answers in the FAQs before reading the user guide. If you cannot find the answer to your question in the following FAQs, search the user guide for what you want to know.

Q. What do I need to use Object Storage?

• You can use Object Storage by applying for a subscription in NAVER Cloud Platform console, creating a bucket, and uploading and downloading a file. For more information, see Object Storage start guide.
• To use Object Storage with an API, first issue an API authentication key from the Portal > My Page > Account Management > Authentication Key Management menu. You can connect the API using the issued authentication key value. For information on how to use Object Storage after connecting the API, see Object Storage API guide.

Q. What is the difference between Manage disclosure and Manage permissions?
A. The Manage disclosure feature is used to disclose a bucket or a file to users around the world outside of NAVER Cloud Platform.

• Disclose bucket: anyone can view the list of objects (files/folders) in the bucket and upload a file
• Disclose file: anyone can open and download a file

Manage permissions is a feature to grant buckets or files permissions to NAVER Cloud Platform users. You can optionally grant desired permissions to specific users.

• Permissions that can be granted in buckets: viewing bucket list, uploading files, viewing Access Control List (ACL), and editing ACL
• Permissions that can be granted in files: downloading files, and viewing and editing ACL

Q. If another account with the bucket usage permission uploads an object, how can I view the uploaded object?
A. When an account holder uploads an object, the account holder becomes the owner. Therefore, the bucket owner has to receive an access permission from the object owner to view the object. See Object ACL API guide to set object ACL with an API.

Q. Can I use tools that integrates with Amazon S3?
A. Object Storage provides an API that is compatible with the Amazon S3 API, so you can use Object Storage as a tool to leverage S3.
To use S3, you have to install the S3 browser and integrate your account using the API authentication key. For more information, see Creating API authentication key integrating with S3 guide.

Q. I downloaded an object, but the actual file size is different from that displayed on the console.
A. When you view the downloaded object on a PC, the file size may be displayed differently because different file size measuring methods are used in each OS. The actual size of the object can be viewed with content-length, and there is no error in the object.

Q. How to access Object Storage in a VPC environment?
A. You can access Object Storage using the following methods depending on the types of subnet in the Korea Region:

• Server built in a public subnet
  • Internet-based communication can be conducted using kr.object.ncloudstorage.com, a public domain.
  • Private communication can be conducted using kr.object.private.ncloudstorage.com, a private domain.
• Server built in a private subnet
  • By default, private communication can be conducted using kr.object.private.ncloudstorage.com, a private domain.
