Vonage’s Open Source Database Odyssey

In an interesting twist of irony, Oracle, which is taking aim at Linux leader
Red Hat for being too expensive, is being undercut with an open
source challenge to its namesake database.

VoIP vendor Vonage Networks is deploying EnterpriseDB, which is built on top of the open source PostgreSQL database as an alternative to Oracle. EnterpriseDB Advanced Server adds Oracle compatibility to native PostgreSQL as well as performance improvements.

One of the key criteria for Vonage’s selection of EnterpriseDB is Oracle
compatibility, which is also why Vonage will use EnterpriseDB in
favor of open source MySQL in some instances, as well.

“Vonage is both a MySQL and an Oracle shop,” Andy Astor, CEO of EnterpriseDB,
told “Fundamentally they found that MySQL was not
able to scale and Oracle’s price was prohibitive.”

Vonage is taking a very methodical step-by-step approach to using
EnterpriseDB in its environment and is not doing a wholesale migration from

“It’s a scale out and complementary deployment, sort of a peaceful co-existence,” Tim Smith, president of Vonage Networks, told

Smith explained that Vonage is using EnterpriseDB in one instance as part of
a ticketing system upgrade.

“We didn’t feel like going all the way to Oracle for it because of the
hardware hunger of Oracle and the cost of Oracle,” Smith said. “We thought
we’d take it to EnterpriseDB and the PostgreSQL compatibility and see where
it goes.”

Vonage is also a user of the open source MySQL database, which Smith views as
being more of an embedded database for Vonage at the low end of the scale,
with Oracle being at the top.

EntepriseDB fits in the middle. According to
Smith, the general idea behind choosing EnterpriseDB over Oracle or MySQL is
to provide more performance, scale and enterprise flavor but without the
cost or complexity.

Vonage isn’t the first VoIP vendor to use PostgreSQL somewhere in its back
end. Skype is also a PostgreSQL user.

At the 10-year anniversary event for PostgreSQL, Skype officially donated a pair of new technologies to PostgreSQL to help management and scalability.

Skype’s use of PostgreSQL had no impact on Vonage’s decision, according to

“We are really just looking for a tool more appropriate for where we are in
terms of scale,” Smith said.

Vonage’s use of EnterpriseDB may well benefit the greater
PostgreSQL community over time.
