So for application/software portability, Docker is your safest bet. Since virtual machines enable true hardware-level isolation, the chance for interference and/or exploitation less likely than with Docker containers. This makes Docker applications easier and more lightweight to deploy and faster to start up than virtual machines.ĭocker containers are generally faster and less resource-intensive than virtual machines, but full VMware virtualization still has its unique core benefits-namely, security and isolation. Since the host kernel is shared amongst Docker containers, applications only ship with what they need to run-no more, no less. However, the tradeoff is a small footprint: unlike VMware, Docker does not create an entire virtual operating system- instead, all required components not already running on the host machine are packaged up inside the container with the application. That said, it’s also possible to run many discreet OS instances in parallel on a single host with VMware-allowing organizations to build true IaaS solutions in-house.īecause Docker containers are executed by the Docker engine (as opposed to a hypervisor), they are not fully isolated. For example, VMware emulates virtual hardware and must account for all the underlying system requirements- subsequently, virtual machine images are significantly larger than containers. Though both VMware and Docker can be categorized as virtualization technologies, optimal use cases for each can be quite different. Platform configurations can essentially be managed as code.
