Overview

Service Overview

Object Storage is object storage that allows users to easily store and use the data they want and can be accessed via URL, making data management very convenient. It enables searching and retrieving large-scale data, and you can leverage features such as encryption and version control. Provides both public and private URLs, and public URLs are accessible over the internet.

Features

• S3 API utilization: Through a Restful API, applications can access it easily and quickly, and since it is compatible with Amazon S3, it can be used effortlessly in applications that integrate with Amazon S3.
• Safe Use: Encryption (SSE‑S3), access control, and Public/Private access features are provided, making it suitable for securely storing user data or backup data for service recovery.
• Cost Efficiency: Users do not predefine the bucket’s capacity and are provided storage space with an efficient pricing model that charges only for the amount used.
• Replication: You can perform replication to a bucket in a different location or the same location. * You can configure multiple replication policies, and if the source bucket becomes unavailable due to a failure or disaster, you can provide service through the replica bucket.
