"Great power comes great responsibility". Why use VM for your application if you only need a “ready-to-use” service. Most of Platform as a Service comes with 99.95% SLA regardless the price or service level you choose. Doing so, you can have more focus on building your Application or create an innovation for your application or your business rather than maintaining VMs properties such as OS patches, SLA, licenses, antivirus, maintenance schedule, OS upgrades, etc.
