2019 IBM Champions for Power Systems Showcase Modern Applications

Selected yearly, IBM Champions are nominated by their peers and selected by an IBM panel. In this article, meet the 2019 IBM Champions for Power Systems class.

IBM Power Systems* clients and business partners are dedicated to the platform and the technologies and innovations it supports. To recognize those who move the platform forward, the IBM Champions for Power Systems program was created to showcase “extraordinary expertise and contributions to the technical community.”

Selected yearly, IBM Champions are nominated by their peers and selected by an IBM panel based on their contributions to the community during the previous 12 months. In 2019, 63 Power Systems experts were identified by IBM as going above and beyond for the platform—spanning the IBM i, AIX* and Linux* OSes. Many IBM Champions are active in promoting the platform beyond business hours through being active in user groups and social media, delivering presentations outside their organizations and more.

IBM Systems magazine, Power Systems, had the opportunity to discuss the platform and community with some of the 2019 IBM Champions. Modern applications and uses like artificial intelligence (AI), machine learning, high-performance computing and blockchain are among the ways the group is using the platform to provide value in the work they do.
