I like that it was easy to set up for our environment with limited resources (we had 1 server). It is much faster than running virtualbox instances at nearly twice speed of VMs we used before using cypherPath container services which has no overhead vs VM's since they are just an image file stored locally as opposed to having OS installed etc into each guest machine - so this makes sense from performance/cost perspective too! Also there were some features not supported out off box such us firewall rules or allowing users access via LDAP authentication but those could be configured easily enough after installation also very flexible configuration options through ansible scripts if needed i guess? Haven't found anything yet dislike about them except perhaps maybe lack support across other major linux distributions e..g CentOS7 instead only RHEL & Fedora currently available unfortunately however Redhat supports their products well including updates even though its paid version compared to community edition versions offered elsewhere.
