Virtual Machine

VMs are resource intensive and can be slow to start up. This means that you’ll need to carefully manage your VMs to ensure that you’re not wasting resources and that you can quickly spin up new VMs as needed. Additionally, you’ll need to be careful about how you manage the lifecycle of your VMs to ensure that you’re not running out of resources or leaving VMs running when they’re not needed which can prove costly.

VMs: VMs run on physical hardware through a hypervisor (like VMware or Hyper-V). Each VM includes a full copy of an operating system (OS), the application, necessary binaries, and libraries, making them larger in size and slower to start. VMs are fully isolated, running an entire OS stack, which adds overhead but provides strong isolation and security.
