As containers move from the developer's workstation into production environments there are many questions about how they fit into a company's existing infrastructure. Should a workload run in a VM or in a container? Should that container run on physical or virtual? In the data center or in the cloud? The reality is that there is no "right" answer, just a series of questions that admins should be asking as they look to figure out where to run their application workloads. In this talk we'll take a look at the key differences between containers and VMs. From there we'll discuss the coexistence of VMs and containers, and finally we'll take a look at key factors to consider when making the decision where to run your applications. Throughout the presentation we'll highlight real world customers, their problems, and their ultimate deployment decisions.
