Scality
Scality is a company based in San Francisco, California that develops software-defined object storage. RING is the company's commercial product. Scality RING software deploys on industry-standard servers to store objects and files. Scality also offers a number of open source tools called Zenko, including Zenko CloudServer, compatible with the Amazon S3 interface. History. Scality was founded in 2009 by Jérôme Lecat, Giorgio Regni, Daniel Binsfeld, Serge Dugas, and Brad King. Scality raised $7 million of venture capital funding in March 2011. A C-round of $22 million was announced in June 2013, led by  Menlo Ventures and Iris Capital with participation from FSN PME and all existing investors, including Idinvest Partners, OMNES Capital and Galileo Partners. Scality raised $45 million in August 2015. This Series D funding was led by Menlo Ventures with participation from all existing investors and one new strategic investor, BroadBand Tower. In 2016, HPE made a strategic investment in the company. In April, 2018, the company announced a $60 million round of funding. Scality announced a refreshed brand, along with a distribution agreement with Hewlett-Packard in October 2014. Scality added Dell and Cisco Systems as resellers in  2015. Products. RING. Scality's principal product is a object storage software platform known as the RING. RING is a multitier architecture and can scale up to thousands of servers and up to 100 petabytes under a single namespace. Ring product depends on a keyspace calculated using a Monte Carlo simulation at install, spread across all of its node servers. While the company aims for the Ring to function without the need of any external management process, a Supervisor server is functionally required to kick-off data integrity operations and keep track of node state, while also providing a single  source of truth for data about the ring itself. The Supervisor process is relatively lightweight and can be installed on a node server if required, but the company recommends it run separately from the Ring's constituent storage servers. The Ring employs erasure coding schemes in multiples of six, which is the minimum number of storage nodes required to install a Ring. The underlying filesystem formatted on the storage drives is transparent to the Ring and it does not interact with filesystem operations directly. The Ring installer was originally written in Python for Saltstack, but then re-implemented closed-source . Object storage was covered by trade press in 2017. Zenko. Zenko is Scality's open source multi-cloud data controller. Zenko integrates data managed on-premises with services available in public clouds. Zenko CloudServer (formerly Scality S3 Server) is an Amazon Web Services Simple Storage Service-compatible open source object storage server. The code is written in Node.js. It is a single instance running in a Docker container, and it uses Docker volumes for persistent storage. CloudServer uses the same code as the Scality RING S3 interface and includes an Apache 2.0 license. It is not a distributed system (that  is the paid version, S3 for Enterprise). However, it does have the same level of compatibility as the S3 interface for the Scality RING. Zenko Orbit is a cloud-based portal for data placement, workflows, and global metadata search. The product enables asynchronous replication between clouds. Versions. Scality has been recognized consistently over the years for object-based storage by IDC. In Gartner's first Magic Quadrant for Distributed File Systems and Object Storage Scality was ranked a leader. Scality was a 2014 storage system software finalist by Storage Magazine. In 2017 Scality was again ranked a leader in Gartner 's Magic Quadrant for Distributed File Systems and Object Storage.
