Machine turn up time

VMs run a fully-fledged OS. Every time a machine needs to be started, restarted, or shut down it involves running the full OS life cycle and booting procedure. A few enterprises employ rigid policies for procuring new IT resources. All of this increases the time required by the team to deliver a VM or to upgrade an existing one because each new request should be fulfilled by a whole set of steps. For example, a machine provisioning involves gathering the requirements, provisioning a new VM, procuring a license and installing OS, allocating storage, network configuration, and setting up redundancy and security policies.

Every time you wish to deploy your application you also have to ensure application specific software requirements such as web servers, database servers, runtimes, and any support software such as plugin drivers are installed on the machine. With teams obliged to deliver at light speed, the current VM virtualization will create more friction and latency.
