CoreOS: An Introduction - Brandon Philips, CoreOS
The architectural patterns of a large scale platform are changing. Dedicated VMs and configuration management tools are being replaced by containerization and new service management technologies like systemd. This presentation will be giving an overview of their key technologies, including etcd, fleet, and docker. Come and learn how to use these new technologies to build performant, reliable, large distributed systems.

Is It Safe To Run Applications In Linux Containers? - Jerome Petazzoni, Docker
Virtual machines are generally considered secure. At least, secure enough to power highly multi-tenant, large-scale public clouds, where a single physical machine can host a large number of virtual instances belonging to different customers. Containers have many advantages over virtual machines: they boot faster, have less performance overhead, and use less resources. However, those advantages also stem from the fact that containers share the kernel of their host, instead of abstracting a new independent environment. This sharing has significant security implications, as kernel exploits can now lead to host-wide escalations.

We will show techniques to harden Linux Containers; including kernel capabilities, mandatory access control, hardened kernels, user namespaces, and more, and discuss the remaining attack surface.

Image Management or Configuration Management? Yes. - Thomas Hatch, SaltStack
A typical enterprise operations team is tasked with managing numerous data centers and public clouds with thousands of virtual machines and containers running heterogeneous software, services and applications. This scenario requires data center automation to help offset the inevitability of infrastructure sprawl and complexity, and to help drive speed, scale and flexibility into the technical core of business. The combination of SaltStack and Docker delivers the potential of extreme simplicity, speed, scale and flexibility for enterprise infrastructures through automation. Learn how to use SaltStack to manage and move Docker images between environments as part of a command and control platform. We will also show how to use the SaltStack module for Docker to get the software pieces in place then step aside as Docker works its magic managing containers on local machines.

Benchmarking Performance of Docker and Traditional VMs - Ali Hussain, Flux7
Docker, a wrapper around LXC containers, provides an excellent mechanism for low overhead virtualization. Docker allows isolated environments to be created in a single machine without imposing a performance overhead.

As organizations look for lightweight alternatives to using virtual machines, they are seeking a better understanding of Docker’s performance capabilities. This talk presents the results from Docker performance evaluations, starting with a bottom-up approach, comparing Docker against virtual machines and native on key performance indicators using microbenchmarks.

Then performance based on a series of real-world benchmarks will be presented. Attendees will also gain insights into how Docker works and how to set up Docker to fit individual needs.

Atomic in Depth: A Look at Project Atomic for Managing Docker Containers - Joe 'Zonker' Brockmeier, Red Hat
Project Atomic, a concept for creating hosts to run Docker containers, was unveiled in April of this year. Rather than producing its own derivative distribution, Atomic is an umbrella project for creating hosts that are optimized for running Docker containers, with an "atomic" update model for the host operating system.

This talk will provide an overview of Atomic along with an in-depth tour of the features offered by an Atomic host, the tools used for creating and updating hosts, and managing Docker containers more effectively. We'll also discuss the implementations of Atomic (Fedora, CentOS, and RHEL) and how to get involved in the Atomic community.
