The days of large IT organizations maintaining systems manually are ending. Today's infrastructure is dynamic, personalized, and malleable. IT infrastructure has become incredibly flexible and complicated as it increasingly uses cloud computing infrastructure in combination with traditional data-centers. To manage such hybrid infrastructures, organizations need configuration management solutions that enable system administrators to deploy and move workloads with ease, without disruption and with consistent behavior across the physical and virtual platforms. This presentation is for infrastructure architects, system administrators and software developers. Mark will discuss the present and future challenges of managing IT infrastructure and will review scenarios and strategies to scale hybrid infrastructures from a few to thousands or even millions of nodes, while ensuring reliability and compliance for all nodes throughout their entire life cycle.
