Cloud storage is a service that lets you store files and data on infrastructure managed by a cloud provider instead of on local disks. It is typically accessed over the internet through APIs, SDKs, or web consoles. Cloud storage systems are designed to be highly durable and available, often replicating data across multiple locations. They can handle everything from small configuration files to large media assets and backups. Pricing is usually based on total storage used plus data transfer out of the provider. Cloud storage is a core building block for modern applications that need to store user uploads, logs, and generated content.
How it Works
Many providers offer object storage where data is stored as objects in buckets with unique keys. Clients upload and download objects using secure HTTP requests, often signed with credentials or temporary tokens. Access control can be fine grained, allowing certain users or services to read or write specific paths. Cloud storage integrates with CDNs to serve files quickly to users around the world. It also ties into backup, lifecycle, and archival features that move data to cheaper tiers over time.
