Walmart’s Take on Open-Source OpenStack Technology


All of Walmart’s e-commerce runs on OpenStack, and the company also is transitioning its retail back-office workloads onto OpenStack.

Walmart, the world largest retailer and one the largest employers, aims to give back to the OpenStack community. In a session at the OpenStack Summit here, Andrew Mitry, lead architect for Walmart’s OpenStack effort, and Megan Rossetti, part of the OpenStack Operations team at Walmart, detailed how the open-source model is working for the retail giant. Mitry explained that Walmart started on its OpenStack journey four years ago with a proof of concept (PoC) deployment. That original PoC made use of leftover and idle hardware as an initial test case for Walmart. The PoC was successful and now OpenStack has helped transform the way Walmart works.

“Today, 100 percent of our e-commerce runs on OpenStack,” Mitry said. “We are now focused on transitioning our retail back-office workloads onto OpenStack, as well.” Mitry noted that now it’s not just web applications that Walmart is moving to OpenStack, but a lot of data intensive applications, as well.
