Chris Pinkham, former Amazon whiz, exits Oracle

Looks like Chris Pinkham has left Oracle(s orcl), just over a year after the database giant purchased his cloud management startup Nimbula.

Pinkham was a former IT infrastructure executive at Amazon(s amzn) where he and colleague Willem van Biljon helped build Amazon’s EC2 service. The two then started up Nimbula in 2008. Nimbula Director, the company’s primary product, aimed to deploy manage workloads across private and public clouds. The product was initially proprietary but added support for OpenStack APIs later.  VMware founder and former CEO Diane Greene was on the Nimbula board.

In March 2013, Oracle snapped up Nimbula — in part for its OpenStack skills — and Pinkham became SVP of Oracle Cloud Product Development. It looks like Pinhkam’s earnout period is over. Pinkham’s LinkedIn profile lists his Oracle tenure as lasting from April 2013 to May 2014.

An Oracle spokeswoman would not comment.

Last fall, Oracle outlined plans to integrate Nimbula into its other hardware and software products.

This story was updated at 1:24 p.m. PST to clarify that Nimbula was not an OpenStack startup.
