I like how easy it is to deploy new versions of my application without having to worry about breaking changes in code or configuration files - just simply updating from one version number to another. It's also super helpful when deploying multiple instances (like dev/stage/production) because all environments are managed separately within each instance. There isn't much dislike; however, there might be better solutions out there if this doesn’t suit your needs perfectly! Deploying separate apps into different VMs with their own configurations has been simplified by using cleaver, as well as managing updates across those apps easier than other similar products available at the time.
