Frequently asked questions about Simple Object Storage

What is an Object Storage solution?

An object storage solution is a modern cloud storage system designed to handle large amounts of unstructured data (like images, videos, backups, logs, documents) by storing that data as discrete units called objects rather than as files in folders or blocks on a disk. Each object includes the data itself, metadata, and a unique identifier, making it highly scalable and ideal for data lakes, archiving, and distributed applications.

What is Object Storage used for?

Object Storage is commonly used for backups, archiving, media files, software distribution, data lakes, and big data workloads. It also serves as the storage backend for AI and machine learning pipelines, where large datasets need to be stored durably and accessed at scale. Exoscale’s Simple Object Storage provides high durability and availability across all these use cases.

How is Object Storage different from file storage or block storage?

Object storage stores data as independent objects with unique IDs and rich metadata in a flat structure, making it highly scalable and ideal for large amounts of unstructured data. File storage organizes data in hierarchical directories, while block storage splits data into fixed-size blocks optimized for low-latency access and traditional applications like databases. A key difference is durability: object storage offers 99.999999999% (11 nines) durability, compared to 99.9–99.999% for local and block storage.

How much does the Object Storage service cost at Exoscale?

Simple Object Storage follows a usage-based model. You pay only for the storage capacity and network traffic consumed, with inbound traffic free. Only egress network traffic outside of datacenters is billed, local traffic between your workloads and Object Storage within the same zone is free. A minimum billable size of 128 KiB per object applies. See our pricing page for current rates, or use the pricing calculator to estimate your costs.

How does Exoscale ensure data security?

Exoscale operates ISO 27001-certified data centers and is fully GDPR compliant. Object Storage data is replicated across three high-availability nodes, and you can enable encryption at rest (SSE-SOS or SSE-C) at no additional cost. Features like versioning and object lock protect against accidental deletions and support immutable backup strategies for regulatory compliance.

Where is my data stored?

All data and replicas remain in the Exoscale zone you select. Simple Object Storage is available in 8 zones across 5 European countries: Switzerland (Geneva, Zurich), Germany (Frankfurt, Munich), Austria (Vienna), Bulgaria (Sofia), and Croatia (Zagreb). Data never leaves the country of your chosen zone, ensuring full data residency and GDPR compliance.
