Object storage is a type of cloud storage that stores data as objects, which consist of data and metadata. Object storage is ideal for storing large amounts of unstructured data, such as images, videos, audio, documents, etc. Object storage provides high scalability, durability, and availability, as well as easy access via HTTP or REST APIs. Object storage is also more cost-effective than other types of storage, such as block or file storage, which are more suitable for structured data or applications that require high performance or low latency.
