<div dir="ltr">Hi Thiago,<div><br></div><div>IMO - no - docker is not a "replacement for VMs". Docker can be used to isolate (and with it make them also transportable) applications from the underlying OS and other apps running on that same host. </div>
<div><br></div><div>Imagine you have a EC2 / RackSpace instance - they charge X per VM instance whether or not you use its CPU 100% of the time, seems like a waste of money ... with docker, you can make sure that you utilise that instance more efficiently. E.g. run 2 apps that need completely different dependencies on the same instance w/o the need to worry about system libs being screwed with as they are fully isolated from each other. </div>
