Over the past year or so, companies such as 10Gen, DataStax and Couchbase have begun to attract investor and customer interest. 10Gen for instance, has raised more than $30 million so far, including $20 million last month from investors such as Sequoia Capital. Couchbase and DataStax have also managed to attract similar funding from the same kind of companies that invested on Oracle and other RDBMS vendors.
Importantly, NoSQL technology vendors have also managed to snag a growing number of marquee customers over the past few months. 10Gen, for instance, claims companies such as Viacom, Disney, SAP, FourSquare, Shutterfly and NetFlix as its customers.
Much of what's happening is similar to what happened with relational databases, Schireson said. Demand for RDBMS technologies first started growing when companies began moving off traditional mainframes and proprietary systems to more open client-server computing models, Schireson said. As enterprises began adopting the new style of computing, they couldn't run their old databases on it and needed an alternative.
"We are seeing a very similar transformation with cloud computing," Schireson said. "The traditional scale-up deployment style is changing to a scale-out deployment model." Applications and databases are increasingly running on commodity hardware infrastructures in the cloud.
There's no doubt that traditional relational database management products will continue to be around for many years, Schireson said. Companies have invested ten of billions of dollars in database technologies from companies such as Oracle and it is highly unlikely that they will walk away from it anytime in the near future. But expect to see many new deployments based on NoSQL technologies, he said.
