Snowflake Computing, a startup that has built data warehouse software based in the Amazon Web Services cloud, announced a new $45 million funding round and made its software generally available.

Snowflake made a big splash when it came out of stealth mode in October with $26 million in funding and a superstar chief executive, Microsoft veteran Bob Muglia.

Since then, Microsoft itself introduced the Azure SQL Data Warehouse service, which is roughly comparable to the service Snowflake has developed.

Meanwhile Amazon Web Services, where Snowflake’s software currently resides, offers the Redshift cloud data warehouse service. And there are other cloud data warehousing startups, such as BitYota.

Snowflake Computing started in 2012 and is based in San Mateo, Calif. To date the startup has raised at least $71 million.

Altimeter Capital, Redpoint Ventures, Sutter Hill Ventures, and Wing Ventures participated in the new funding round.
