The choice for I/O intensive applications

Based on it’s unique characteristics, block storage is the choice for mission-critical and I/O intensive applications. It can be used for relational or transactional databases, time series databases, containers or hypervisor file systems. Because Volumes are directly connected to an instance, their I/O speeds are much faster than those of an alternative storage solution like Object Storage.

Flexibility for containerized applications

With being equally flexible, scalable, and efficient, block storage is the perfect match to containerized applications on the cloud. Containers benefit from the speed of block storage and the native ability for a single host to mount multiple blocks. Seamlessly migrate between servers, locations, and operating systems.

Storage FAQ

Why should I use block storage instead of local storage?

Local storage on Exoscale Compute instance is already a block storage device. The main difference between the 2 types of devices is that the local storage cannot be easily detached and reattached to another compute instance. Other attributes differ as well, mainly around the size flexibility where Local Storage is bound to minimum and maximum limits associated to the instance type versus Block Storage that can be used up to 10 TiB per volume.

What is the difference between block storage and object storage?

Object Storage is an unlimited and unstructured storage service that is accessed over an HTTP REST API and can be directly used by applications or even client side web browser. With Object Storage only the effective size of objects within a bucket are charged on a per GB basis. On the other hand, Block Storage is a low level storage service that is designed to mount Volumes at the operating system level. Each volume has a fixed capacity when attached to a Compute Instance. Applications or databases backend that need to store data to a volume need to rely on file system primitives offered by the operating system.

How are Block Storage Volumes charged?

Block Storage volumes are charged per GiB.hour for the full provisioned capacity of the Volume. They are accounted whether the volume is attached or not to an instance and the resolution goes down to the second.

Can Block Storage Volumes be resized?

Block Storage Volumes can be resized throughout their lifetime to an upper value in one operation. The scale volume function is available via the API, CLI or Portal. The file system hosted on the volume requires an expansion after volume size increase.
