CTERA vs ownCloud

CTERA Networks is a cloud storage and data protection hardware and software company that specializes in cloud storage gateways, which are integrated with a datacenter or cloud-side service delivery platform, CTERA Portal. It provides network storage combined with asynchronously replicated off-site cloud storage. CTERA markets cloud storage gateways that use traditional file-based NAS protocols with replication to cloud storage.

ownCloud is a suite of client-server software for creating file hosting services and using them. ownCloud is functionally very similar to the widely used Dropbox, with the primary functional difference being that ownCloud is free and open-source, and thereby allowing anyone to install and operate it without charge on a private server, with no limits on storage space or the number of connected clients. Despite the name, the software system does not use cloud computing unless it is manually configured.
