An impressive Postgres milestone
"Until now, Heroku's Postgres database service – originally launched in 2007 – has only been available to Heroku customers for use with Heroku platform apps," said Matthew Soldo, a product manager with Heroku. "With measured service uptime of four nines (99.99 percent), and designed data durability of eleven nines (99.999999999 percent), the service is trustworthy for mission-critical data. 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."
To date, Soldo said Heroku Postgres has written 19 billion customer transactions. It processes 400 million write-transactions every day.
