NEC is ready to provide Highly Available and Maintainable Cloud platform with Application

Continuity, Real Application Clusters, Oracle Multitenant, Oracle Security options and

WebLogic Server Active GridLink on NEC HW.

I believe this platform brings phenomenal value to our cloud customers because it hides

unplanned outages and scheduled maintenance from application users.

Deputy General Manager, NEC Corporation
