I work for a large Unnamed Parcel Service and all of our future applications are going to Azure Kubernetes Service, which is the Microsoft-managed k8s offering. There are still a ton of legacy applications running on all sorts of platforms, from mainframe to just about any technology you can name from the past 40 years, but everything going forward is being written for .Net Core running on Linux containers in AKS. So you don't have to switch everything immediately, you can get around to it eventually but at least you can start to build up a pool of talent and skill set towards that goal.
