Virtual Machines vs Containers
- Virtual Machines
- runs a full-blown guest OS with virtual access to host resources through a hypervisor
- bins/libs (included with guest OS and installed additionally for application(s)) are independent between VMs
- in general, VMs incur a lot of overhead beyond what is being consumed by your application logic
- Containers
- runs natively on OS and shares the kernel of the host machine with other containers
- bins/libs are shared between containers through the Container Engine
- it runs a discrete process, taking no more memory than any other executable, making it lightweight
- Mediator
