Investors are betting big money on hybrid cloud storage as an attractive option for enterprises. Hybrid cloud vendor Cloudian has raised $24 million in new funding, the company announced today, bringing its total financing to $44 million. Cloudian’s thesis is that cloud storage often works best when paired with on-premises storage. That dual approach offers companies the speed and scalability of cloud services like Amazon Web Services, CloudStack, and OpenStack while enabling enterprises to keep their most sensitive data on their own private servers. Cloudian chief executive Michael Tso is keen to differentiate his company’s offering from cloud storage services like Box, Dropbox, and Egnyte.
