 When a magnitude 7. 1 earthquake struck off the southwest
coast of Taiwan
at 8:26 pm local time on December 27, 2006 thousands of offshore developers had
to go home. They had no choice. Undersea cables were damaged, severely disrupting
phone and Internet access in Taiwan,
China, Hong Kong and Singapore. O2Micro had implemented WANdisco's multi-site replication
solution company-wide in late 2005 including their remote sites in China and Taiwan. That meant that their
developers in China did not
need to have direct access to a central CVS server in the US.So what happened at O2Micro after the earthquake struck? - Listen to a podcast interview about this story When a magnitude 7. 1 earthquake struck off the southwest coast of Taiwan at 8:26 pm local time on December 27, 2006 thousands of offshore developers had to go home. They had no choice. Undersea cables were damaged, severely disrupting phone and Internet access in Taiwan, China, Hong Kong and Singapore. O2Micro had implemented WANdisco's multi-site replication solution company-wide in late 2005 including their remote sites in China and Taiwan. That meant that their developers in China did not need to have direct access to a central CVS server in the US. So what happened at O2Micro after the earthquake struck? [ Listen to the podcast ] Nothing. Steve Krems, Director of Technology for O2Micro, attributed this resilience to WANdisco. WANdisco's distributed architecture doesn't rely on master servers, or central transaction managers that can quickly become single points of failure when networks are disrupted. Each site had its' own copy of the data that local developers work against. When the earthquake struck and Internet connectivity was lost, those developers simply continued to develop against their local source code repository. When the Internet was restored their work was automatically synchronized with O2Micro's other sites world-wide. No work was lost and there was no downtime. No administrator had to get involved with manually re-synchronizing the servers when the network came back up - WANdisco took care of that. WANdisco's customers have experienced unforeseen disasters in the past. Buildings have burned to the ground, taking servers out completely, but developers were able to move to another building and simply point to another server at a different location. Finally, O2Micro has implemented WANdisco's security features to insure that the same access controls are in place across all sites. This meant that there was no opportunity for anyone to gain inappropriate access to source code repositories while their sites were out of communication.
