Is (system) virtualization becoming legacy or old style? Sounds a strange question, but there are three main trends that are changing the role and the weight of virtualization in the IT:
- Competition and more choices and options: VMware vSphere is still the leader (in most cases), but other hypervisors like Hyper-V and KVM are growing fast and become mostly features comparable.
- Cloud management and cloud services: in most cases virtualization is hidden by the managemed and also for IaaS cloud virtualization is not necessary mandatory (see also virtualization is not cloud).
- Container and microservices: are moving new application to a new level of abstraction (and automation); in some cases virtualization is used to provide containers, but still is not mandatory.
