I also think it's worth mentioning that Intel® Clear Containers now supports Docker as well.

Arjan van de Ven (from Intel) can share more context.

It's fantastic that you've reduced the startup and memory overhead to the point where it's almost negligible. That's quite an achievement!

One thing that was not discussed is the impact hypervisor-based virtualization has on runtime. I've seen plenty of benchmarks where AWS EC2 instances perform much more poorly than a bare-metal machine with a similar processor. Do you have any idea what the overhead might be for clear containers vs standard linux namespace-based containers?

This might be viewed as slightly OT but this entire container security thing always reminds me how important it is to build on the right ecosystem.

This technology has been available for years on other platforms in a stable fashion. The fact that they never get used for different reasons is always sobering

It's probably similar to our results from last year: http://domino.research.ibm.com/library/cyberdig.nsf/papers/0...
