What Is Cloud Storage?
Cloud storage covers object storage, block storage, and managed databases hosted by the provider with built-in redundancy. In practice, this means your data stays available even if a physical drive fails somewhere in the data center, because it has already been copied across multiple disks or facilities before that failure happens.
Each storage type solves a different problem. Object storage handles unstructured files at massive scale, block storage attaches directly to a compute instance like a hard drive, and managed databases add structured querying with automated backups on top.
Object Storage vs Block Storage vs Managed Databases
Object storage is built for files you access less predictably: backups, media, logs, and large unstructured datasets, priced per gigabyte stored per month. Block storage behaves like a virtual hard drive attached to a specific compute instance, used for operating systems and application data that need low-latency access.
Managed databases go a step further, handling patching, backups, and failover for you, so your team manages the schema and queries rather than the underlying infrastructure.
- Object storage for unstructured files and long-term backups
- Block storage attached directly to compute instances
- Managed databases with automated backups and failover
- Built-in redundancy across multiple physical drives
- Data remains available even during hardware failure
- Storage billed separately from compute and bandwidth
Choosing a Cloud Storage Provider
Compare durability guarantees, how many regions data is replicated across, price per gigabyte stored, and egress fees for moving data out of the platform. Egress pricing in particular is easy to overlook and can dominate your bill if your application serves large files to end users.
Cloud storage is data storage hosted by a provider, delivered as object storage, block storage, or managed databases, with redundancy built in so your data survives individual hardware failures.
Object storage handles unstructured files like backups and media at scale, priced per gigabyte stored. Block storage behaves like a virtual hard drive attached to a specific compute instance, used for operating systems and low-latency application data.
Providers replicate data across multiple physical drives, and often multiple facilities, so a single hardware failure does not result in data loss or downtime.
Yes. Managed database services are a form of cloud storage that adds structured querying, automated backups, and failover on top of the underlying storage layer.
Compare durability guarantees, replication regions, price per gigabyte, and egress fees for retrieving or transferring data out, since egress costs are often the biggest hidden expense.
