Mission-critical Employee Portal now Delivers Improved Availability, Reliability October 12, 2012,
Volume 176, Issue 2
Facing the stupendous rise in social media, video streaming, live broadcasting and other disruptive developments in wireless technology Verizon responded by implementing MySQL on Linux as the backend, the LAMP stack for Vzweb, its mission-critical, 24x7 employee portal, with Drupal as the front end. Vzweb is the main internal communication channel for Verizon Wireless, while Vztube hosts important company-wide webcasts regularly for executive-level announcements, so both channels have to be live and accessible all the time for its 78,000 employees across the United States. Verizon has supported these with MySQL 5.1 since3 2010. High connection spikes occurred during such events as Hurricane Irene causing slow user response time, and the IT team applied workarounds to continue the service. A number of key performance indexes (KPI) for the infrastructure were identified and the operational framework redesigned to support a more robust website and conform to the 99.985% uptime SLA (Service-Level Agreement). Verizon took a number of steps, the last of which was to upgrade successfully from MySQL 5.1 to to the latest GA release MySQL 5.5 in 2011, and leverage MySQL Thread Pool as part of MySQL Enterprise Edition to scale better.
