Overview

Service Overview

Object Storage is an object storage that allows users to easily store and use the data they want and enables URL-based access, 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 public and private URLs, and the public URL can be accessed over the internet.

Features

• S3 API utilization: Through a Restful API, applications can access it easily and quickly, and because it is compatible with Amazon S3, it can be used effortlessly in applications integrated with Amazon S3.
• Secure 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 fees based on usage.
• 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 the service through the replica bucket.
