Re: Dev and Ops, will the two ever meet?
In my opinion, devs and ops will have more and more overlapping and interaction. For example, in my organization the developer has on-call duty to carry pager to solve the operation problems. This provides developer a wider view on the system. I think VM and Container will complement each other instead of one replacing the other - Container provides more efficiency and flexibility.

Google testimony on multiple containers per VM
Craig McLuckie said after the press conference that it wasn't unusual for Google to run 200 containers in a virtual machine. Part of the joint development of Kubernetes is to allow it to provision and manage gorups of containers, with groups put inside a VM. Monitoring and managing individual containers is a time-consuming, attention demanding way to go.

Dev and Ops, will the two ever meet?
Laurie, the possibility of something going wrong amid hundreds of thousands of lines of Linux code versus the 30-40 commands of the hypervisor is a concern to operations managers.  They've spent a lifetime trying to secure legacy applications and they're the ones, largely, running the virtualized data center. The next gen app developers see it differently: secure our containers so we can enjoy the efficiencies.

Containers on bare metal
Interesting point re the attack surface being bigger when you run containers on bare metal, Charlie. Does that seem to be a key concern among attendees, or is it more theoretical due to the low number of exploits?
