The Heroku Postgres database-as-a-service product was announced by the company on Wednesday. It is a PostgreSQL database that sits on top of Heroku's platform-as-a-service, which is in turn mounted on top of Amazon's Amazon Web Services (AWS) infrastructure-as-a-service cloud.

"With measured service uptime of four nines (99.99 percent), and designed data durability of 11 nines (99.999999999 percent), the service is trustworthy for mission-critical data," Matthew Soldo, a Heroku engineer, wrote in a blog post. "As of today, these production-quality Heroku Postgres databases are independently available for use from any cloud platform, provisioned instantly, metered by the second, and without contract."

The Heroku database has broad compatibility with a range of clouds. Applications built on top of Heroku, Google App Engine, Microsoft Azure, VMware's Cloud Foundry or Amazon Web Services' Elastic Compute Cloud (EC2), or the developer's own computer, can connect to the service. Supported languages include Perl, Python, Ruby, Scala, Go, Tcl, C and C++, Java, .NET and Javascript.

Heroku Postgres launched with the general Heroku platform in 2007. To date it has "successfully and safely written 19 billion customer transactions, and another 400 million write-transactions are processed every day", Soldo wrote.

Pricing ranges from $200 (£124) per month to $6,400 depending on the size of the cache. There are six separate payment plans available.

Heroku services can fail if there is trouble in the underlying AWS cloud. In April Heroku was knocked offline for betwteen 16 and 80 hours, depending on the type of application, due to problems in AWS.
