The simplicity with which you can create, deploy & manage your VM's is awesome! I was able t solve problems that would have taken months or years using traditional methods (like VMware).
There are many options for what configuration should be used when creating an image, so it takes some time getting familiar w/ them all but once everything starts working its easy peasy!! Have tried most popular hypervisor providers including AWS EC2 AMIs - they dont compare at this price point yet. We use nanoVM as our primary platform because we needed something more reliable than Docker Swarm since we were deploying sensitive applications in production environments where out-of-band access wasn't available 24x7. It has allowed us to achieve 99% uptime across multiple data centers without having any down times from issues like host OS patches causing containers not start up properly etc..
