Prerequisite Knowledge

Attendees should have a working passion/interest in OpenStack, Docker and cloud computing environments.


It’s no secret: Walmart’s internet technology hub WalmartLabs is using open source development to help 245 million weekly customers around the world shop Walmart for online, on mobile or in stores. In the past few years, WalmartLabs transformed from buying to building its own e-commerce technology in-house. That included re-building all aspects of its technology stack to rival the best companies and investing in open source technologies like Cassandra, OpenStack and Node.js to name a few. WalmartLabs is also contributing a lot back to the community with products like hapi and mupd8.

For a developer at Walmart, this means they have the freedom to use the open source software that helps them deploy their applications to customers fast. This talk will focus on the technology that’s making this a reality for WalmartLabs:

  • mIaaS and Walmart’s use of OpenStack — one of the largest enterprise implementations of OpenStack today, with upwards of 100,000 cores.
  • PaaS and how Walmart accelerated its roadmap by completely automating every piece of the application lifecycle with OneOps.
  • Learn why PaaS and IaaS were not enough and how Walmart defined its own vision around Software Defined Applications to fill the gaps.
