Scality brings hybrid cloud storage virtualisation –

Object storage specialist Scality has launched, an open source cloud storage control layer that allows customers to manage storage across in-house storage and public cloud tiers.

The cloud controller is based on Scalitys 2016 launch of its S3 server, which provided via Docker container deployment S3 access to Scality Ring object storage.

Paul Turner, chief marketing officer (CMO) for Scality, said would allow users to mix and match Scality on-site storage with storage from different cloud providers.

Users want a multi-cloud environment, to be able to choose between the differing qualities of different clouds. provides a single interface to any cloud via S3 APIs[application programming interfaces], he said.

S3 is Amazons cloud storage protocol, which has emerged as a de facto standard for input/output (I/O) to and from cloud environments. Storage is the most popular use case for cloud customers, a recent survey found. is freely downloadable and allows Scality customers to maintain their datas native cloud format, carry out metadata searches and build in workflow-based triggers to, for example, replication.

The offering is likened by Scality to being a control layer. It effectively provides a form of storage virtualisation that is a layer of abstraction in which the customer can manage in-house and public cloud storage from a single screen.It allows the customer to decide what to do with data, how it is stored, mirrored and protected, said Turner.

It is aimed at customers wanting to burst workloads to the public cloud, for example, runninganalytics using cloud compute instances or machine learning workloads that have heavy central processing unitrequirements at key phases.

What does not solve, however, is the issue of data portability. Data is held in each cloud in that clouds data format, and migrating data from that cloud to another is not an automatic process. This means data can potentially be trapped in a providers cloud or incur a cost to move it elsewhere.

Turner said Scality is working on the ability to drag and drop between clouds.This doesnt provide the answer to data portability between clouds. It provides the ability to read back with a single S3 call and to write to another cloud, he said.You could drag and drop between clouds, but not yet. We havent written that yet, but it could be extended to move, map and exchange data.
