NBCUniversal is implementing DevOps practices like continuous integration, delivery, and testing using tools from IBM like UrbanCode Deploy, IBM Dev-Test Environment as a Service (IDTES), and IBM Cloud Orchestrator. This allows them to continuously test code, deploy applications across hybrid clouds, and improve collaboration between development and operations teams. NBCUniversal's DevOps practices aim to address issues like slow release processes and lack of integration between development stages.
