How it works and why to use S3 Object Storage

S3 storage is a facility storage service offered by cloud service providers. The main advantage of the solution is the ability to store files of any type, any size, with a high level of reliability and availability.

The principle of working with S3 storage comes down to creating containers and adding the necessary files there, which are represented as objects. Thus, everything that falls into the container can be viewed, moved or deleted. The containers themselves, if necessary, can also be removed.

An important point: in addition to the objects themselves, metadata is stored in object storages that determine the properties of the object and a unique global identifier in the form of an assigned address. These attributes are stored in a flat address space, eliminating the problems encountered when working with a hierarchical file system based on complex file paths. It is noteworthy that one object may contain heterogeneous metadata that characterizes it in the most detailed way. For example, it can be an audio file with the specified metadata in the form of an artist, song, album, and other information. In the future, file metadata is indexed, which greatly facilitates and significantly accelerates the search for the desired objects by the specified criteria.
