SmartOS is a hypervisor lean enough to run entirely in memory, powerful enough to run as much as you want to throw at it. Provisioning is blindingly fast, thanks to zones and ZFS file system creation.
The ZFS file system guarantees data integrity, with particular emphasis on preventing silent data corruption.
OS virtualization with highly secure sparse zones (most system software is read-only), and KVM for legacy apps, provide the most secure virtualization on the market.
Based on the illumos kernel, a descendant of Solaris - the most trusted enterprise operating system in computing history. Additionally, SmartOS runs from a live image: there's no such thing as a failed upgrade when you can simply roll back to an earlier image.
The Service Management Facility (SMF) helps you recover more quickly from system failures and manage through service slowdowns. Fair share scheduling, CPU caps, and disk I/O throttling ensure good neighbor behavior in massively multi-tenant environments.
When something doesn’t behave as it should, you need to be able to find out quickly what is wrong and why. Dynamic tracing lets you see everything that's happening throughout the software stack - safely, in real time, in production.
