Containers in Linux: Current State and Where We're Going - James Bottomley, Parallels
 (James Bottomley, Parallels)Containers have seen a lot of excitement in recent months, particularly with the advent of docker.  This talk will describe some of the history of containers in Linux, starting with the first implementation in 1999, where we are today with container unification, which is largely complete in the kernel, but which has some way to go in userspace and how, with the advent of libcontainer as a unifying feature for all Linux container projects, how we might both unify the control planes of all Linux containers as well as expose novel features that facilitate the next generation of containerised applications.

Group Based Policy: Open Source Policy in OpenDaylight and OpenStack Neutron - Kyle Mestery, Cisco
As computing has continued to evolve to a more utility or cloud-like environment, one area which has not evolved as much is networking. Concepts relevant 20 years ago such as ports, networks, subnets and routers are today still very much the basic building blocks for operators and application deployers. Group Based Policy looks to change this landscape by introducing the concepts of groups of endpoints and policy abstractions governing the communication between the groups. With Group Based Policy, application deployers can think in terms relevant to their applications when deploying networking for their applications. This talk will cover an introduction to Group Based Policy and explore it’s implementation in OpenStack Neutron and OpenDaylight. An overview of how the two work together to achieve harmony for application deployers will also be discussed.

Orchestrating Shared Networks, Physical LB and DNS on Cloudstack - Mauricio Kilikrates Alexandrino Nicolia dos Anjos, Globo
The adoption of Cloud Computing Solutions in datacenters worldwide has proven to be the right path, as it reduces costs, automates operation tasks and improve time-to-market for newly developed applications. However, cloud solutions are still in an early stage and do not meet all requirements for company environments, especially those with high capacity
With that in mind, Globo.com embraced an open cloud solutions, Cloudstack, and began developing together with the community to fulfill all its high availability, high capacity and high throughput requirements. Integration between Cloudstack and Globo.com’s infrastructure happens in all levels, with an special attention to network equipment management, DNS automation and load balancing
In this presentation, Globo.com will show the challenges in adopting cloud computing for its services and how these challenges were met with newly develop

Xen Project 4.4: Features and Futures - Russell Pavlicek, Citrix
The 4.4 release of Xen Project is no minor "point" release of software. This latest release from the original enterprise-ready Open Source hypervisor contains some important additions, most notably the arrival of the new experimental PVH mode. Dubbed Paravirtualized Hardware mode, PVH represents a new leap in paravirtualization: Paravirtualization within a hardware container, resulting in potentially higher performance for your cloud. Beyond PVH, Xen Project is also making inroads in other areas. Recent enhancements include additional support for the ARM architecture, improved FreeBSD support, additional libvirt support for the libxenlight toolstack, the release of MirageOS, and more. The presentation will conclude with an overview of current efforts under development as well as planned future enhancements.

Simulating the Internet Using Unprivileged LXC Containers - Stéphane Graber, Canonical
Did you ever want your own Internet in a bottle, where you can easily look at exactly what's going on, what path every single packet is taking, where you can bring down any link you wish or even a whole country if you feel like it?

Well, this is exactly what the NorthSec 2014 implemented for their security contest back in April, a small, self-contained version of the Internet, made of around 300 routers, spread across a fake planet but with real latencies, using the same routing technology as the real thing, allowing for very easy analysis and debugging of every single connection. All of that using unprivileged LXC containers and a recent Linux kernel!

In this presentation, Stéphane Graber will go through the creation process for this work, demo the final result and what's possible to do with it and hilight some of the kernel bugs and limitations which had to be overcome.

Cache Strategies For Microservice-Based Web Apps - Glen Campbell, Rackspace
Many web applications are now composed of data from multiple backend services, each focused on a specific domain of data. Handling these services can cause performance issues because "over the wire" data is orders of magnitude slower than locally-available data. 

This session is a broad overview of a variety of methods and architectures for caching data to improve performance. These techniques range from autonomous HTTP caches like reverse proxies to manually-managed cache systems like memcached and others. In addition, there are techniques for caching SQL and NoSQL database data to avoid repetitive queries. 
Web apps that use multiple microservices can also benefit from architectural changes such as adding a service aggregation layer to minimize HTTP requests and improve the cacheability of the data.

Tuning Applications For Your IT Infrastructure: What Can Go Wrong - Rosemary Francis, Ellexus
Even when the software and IT infrastructure have been well designed, installation and configuration problems often arise. In high-performance computing, developers often spend a lot of time optimising their code. However, the deployed system will inevitably be designed differently from the development environment. When moving applications from local storage to a distributed system, something as simple as a file stored in the wrong place can significantly affect performance. Accessing the file system unnecessarily can slow down the network and hinder other jobs that share that resource. In this talk Rosemary will be sharing some of the ways in which software can be miss-configured and how those problems may be avoided in future. She will outline design decisions and best practices that we will all have to care about more as applications move to the cloud.

Troubleshooting as a Service - Sagi Brody, Webair Internet
As the standardized offerings for hosting and cloud providers become more complex and interdependent, so too do the requirements to properly manage and troubleshoot them. The ability for technical teams to quickly localize bottlenecks, capacity limits, application issues, and other problems is now a key factor for a provider’s success. Whereas troubleshooting was considered a soft skill in the past, hosters must acknowledge and nourish the importance of this most important ability.

Running OpenStack at Scale: Beyond the Private Cloud Proof-of-Concept - Dan Yocum
Many companies are evaluating OpenStack at the small, proof-of-concept scale: a few compute nodes or VMs, a single headnode controller with an integrated database and amqp server. Everything is working, the management team is happy, and the order is given to make it bigger and make it go.

Scaling out a PoC to a full, highly available solution with dozens of compute nodes, a large shared filer for VM image storage, load-balanced clustered database, and a fully optimized AMQP server is a completely different environment and requires dedicated staff, robust monitoring and alerting, and knowledge to get the cloud to an operational state and keep it stable with a 6 month OpenStack release cycle.

We outline how the OpenShift Online Operations team deploys, maintains, and tunes the the Red Hat OS1 Internal OpenStack cloud environment, which currently is home to ~1,300 VMs used for Red Hat development, training, customer demos, and proof-of-concepts.
