They are using their own Illumos-derived distribution, SmartOS, which combines greatest features inherited from Solaris: ZFS, Zones, Dtrace, crossbow...
It run SmartOS containers and Linux containers (via ABI translation), alongside VMs (using their port of KVM), everything being encapsulated into Solaris Zones..
They claim to offer better performance by removing some virtualization layer (and because of the supposed superior performance of their SmartOS hypervisor), and better security because they use solaris Zones, crossbow network virtualization..
You can even use use Dtrace inside Linux Containers..
They implemented Docker API at the datacenter level (via their SmartDatacenter software they opensourced in 2014), the data center is seen as a single, elastic Docker host. Everything is opensource
A preview is available, on-premises or as an hosted service.
Are SmartOS and the solutions built on top of it hidden gems, wrongfully ignored because not being Linux ? A better platform to run Linux than Linux ?
Is this a breakthrough Docker-Wise ? Or an attempt of a niche-player to grab some attention ?
What are the comparable offers running on Linux ?"
