S3

Amazon S3 is a virtual storage system that can be accessed from anywhere with an internet connection. Users configure the storage to suit their requirements and set priorities for objects.

Features

Amazon S3 has built-in options for end users:

1. Storage Lens. A monitoring and analytics tool that provides customers with detailed information about disk space usage on rented storage. It provides users with best practices for reducing rental costs, improving storage profitability, and recommends relevant measures for protecting information.
2. Intelligent-Tiering. This service optimizes disk space on the selected virtual storage system. If data has not been requested by the user within 30 days, it is automatically moved to the “infrequent” access area. After 90 days, the information is transferred to the “archived data” area (Archive Access level), and after 180 days, to the Deep Archive Access level. This allows users to work with data at maximum access speed.
3. Access Points. Allows customers to create unique node names (identifiers) that facilitate the management of information volume on virtual storage systems. With this technology, users can scale storage, implement dedicated access zones, or differentiate rights.
4. Batch Operations. This tool is analogous to group policies. Administrators create a task (policy), write rules, and select objects to apply them to. Tasks can be grouped into sequential lists, prioritized, and changes can be recorded in the event log.
5. Block Public Access. The service blocks access to public data based on user selection. The object of the block is a storage element, directory, or user account. In the latter case, access to all information linked to the account is blocked.

Classes

Amazon S3 divides data into classes depending on user requirements:

1. The first (Standard) is a traditional data storage option. It is suitable for the classic cloud data storage model or for startups.
2. The second model (Standard Infrequent Access) is used for backing up information or restoring from backups.
3. The third option (One Zone-Infrequent Access) is suitable for objects that are rarely accessed but require urgent information. This class moves information to a special zone where read speed is a priority.
4. The fourth (Glacier) is used for long-term storage of data that is rarely accessed and is not a priority. This is a complete analogue of tape libraries.
