Types of Cloud Storage

Cloud storage can be categorized into three primary types, each designed to address different storage needs:

Object Storage

It is ideal for storing unstructured data, such as images, videos, audio files, and documents. It uses a flat structure, where each piece of data is stored as an object with a unique identifier. Object storage systems are highly scalable and can efficiently store massive amounts of data. They are well-suited for content distribution, backup, and archival purposes. Popular object storage services include Amazon S3, Google Cloud Storage, and Azure Blob Storage.

File Storage

File storage in the cloud mimics traditional file systems. It organizes data into directories and subdirectories, making it suitable for structured data that requires a hierarchical structure. File storage is commonly used to share and collaborate on documents, manage user files, and host web content. Services like Amazon EFS, Google Cloud Filestore, and Azure Files offer scalable and managed file storage solutions in the cloud.

Block Storage

Block storage provides raw storage volumes that can be attached to virtual machines (VMs) and used for various applications, including databases and enterprise applications. Unlike object and file storage, block storage does not organize data into files or objects. Instead, it presents storage as a sequence of blocks that can be written to and read from. This low-level access makes block storage highly versatile but requires careful management by the user. Leading block storage services include Amazon EBS, Google Persistent Disk, and Azure Disk Storage.

Cloud Storage Use Cases
