The nation's second-largest city is part of the largest deployment of Google Inc.'s cloud computing products.

To eliminate a $400 million IT deficit, Los Angeles chose Computer Sciences Corp. to transition all 30,000 employees from an in-house Novell Groupwise e-mail system, which didn't work on some mobile devices, to Google Apps for scheduling, archiving, and disaster recovery communications in addition to e-mail. The $7.25 million contract is expected to save $5.5 million over five years.

To protect against any loss, the contract requires Google to compensate the city if the system's integrity is breached.

The system has no effect on any ESRI products used by the city's public works, recreation and parks, or transportation departments.
