(Tutorial) OpenStack Tour de Force - Florian Haas, hastexo
Call us crazy, but here is where we stand up an OpenStack cloud, from scratch, in two hours. First presented at OSCON 2013 and running full throttle through the basics of OpenStack, this fast-paced tutorial will whirl through authentication, image storage, networking, and compute at breakneck speed. Not for the faint at heart. A strong sysadmin or devops background is an excellent asset to bring along to this tutorial, but no prior knowledge of OpenStack is required. (If you do bring it to the table, though, it certainly won’t hurt.) Prior Puppet knowledge is also a plus, as this tutorial will use Puppet for automated deployment and configuration.

TripleO: OpenStack on OpenStack - Monty Taylor, HP
Typical cloud deployments - be it Openstack, Eucalyptus etc - have a separate control layer installed and upgraded using separate tools (which might be hand-configured PXE + preseeding, Cobbler, Orchestra/MAAS, FAI etc). As a result you have two distinct provisioning systems in play, which allows for more user error and increased special cases in automation. Using Openstack’s bare-metal hypervisor, my team are building a fully self contained cloud, where the control layer for the cloud is itself deployed and upgraded via the same cloud API. Audiences should be anyone looking to deploy complex cloud applications, or anyone looking to deploy OpenStack. They should expect to leave the talk with all of their notions about large-scale application deployment stood soundly on their head.

Efficient and Large-scale Infrastructure Monitoring With Tracing - Julien Desfossez, Efficios Inc.
Tracing is a powerful tool to help solve problems in high-performance multi-threaded applications. There are success stories of custom application tracers deployed in large distributed environments, but we almost never see a low-level system tracer deployed in such environments. With the features introduced in LTTng during the last year, we can now extract remotely and in real-time relevant informations about running production servers efficiently. We will demonstrate how LTTng can be deployed in a cloud infrastructure (0penStack) to extract high-precision metrics remotely, how to enable/disable kernel and user-space events dynamically, and how to extract traces on crashes. This presentation will give system administrators a new perspective on how to monitor and debug production servers in large-scale data-centers.

MySQL in the Cloud, Colin Charles - Monty Program Ab
Today you can use MySQL in several clouds in what is considered using it as a service, a database as a service (DBaaS). Learn the differences, the access methods, and the level of control you have for the various cloud offerings: Amazon RDS, Google Cloud SQL, HPCloud DBaaS, Rackspace Openstack DBaaS. The audience level is intermediate users of people that want to use the database in the cloud. Expect to learn about the administration tools and ideologies behind DBaaS and the "locked-down" environment. Some considerations include: different backup strategies, planning for multiple data centres for availability, where do you host your application, how do you get the most performance out of the solution and most importantly What does this all cost?

Building Web Scale Using Open Source on the Internet Assembly Line - Thomas Hatch, SaltStack
Old cloud factories are not equipped with tools that are fast or scalable enough for the new, real-time Internet assembly line. Tom Hatch, SaltStack founder and CTO, spent years as a cloud builder / systems administrator and in the process used most of the systems management tools available. But the tools were insufficient for the job at hand. So Tom created Salt from his basement, written in Python, with the idea to create a new breed of open source tools for real-time data center automation, beyond just configuration management. These tools are built for speed and scale and help automate management of the entire data center stack, beyond just development, for real-time infrastructure operations and Web-scale apps. He will show how these new, open source tools are being used by web-scale DevOps teams at LinkedIn, WikiMedia and OpenStack to quickly deploy Web scale.

Securing Your Xen-Based Cloud - George Dunlap, Citrix
Xen is a mature enterprise-grade virtual machine with many advanced security features which are unique to Xen. For this reason it's the hypervisor of choice for the NSA, the DoD, and the new QubesOS Secure Desktop project. While much of the security of Xen is inherent in its design, many of the advanced security features, such as stub domains, driver domains, XSM, and so on are not enabled by default. This session will describe all of the advanced security features of Xen, and the best way to configure them for the Cloud environment. When the audience leaves, they should have a general framework to evaluate the security of their system, know the key security features of Xen, and have a basic framework of knowledge to help them make sense of the documentation. This talk will *not* go into mind-numbing detail about specific commands to type or configuration options.

Systemd-Nspawn is Chroot on Steroids - Lennart Poettering, Red Hat
systemd-nspawn is a simple container manager for Linux systems that is shipped as built-in component of systemd. systemd-nspawn is as easy to use as chroots, but suitable for booting up full-blown Linux systems. It's great as light-weight container tool that just works. systemd-nspawn makes working with containers easy. In this presentation I will introduce you to systemd-nspawn, and show how you can set up a bootable Linux container in a one command, and then boot it up in a second one -- and all that with built-in tools of your favourite (systemd-based) distribution. You might learn a thing or two about Linux containers in general, and the technology they build on. We'll discuss how we are working on integrating container support as closely into the core OS as possible, trying to provide similar integration as Zones on Solaris.

SSD and HDD Performance Testing - Christoph Mitasch, Thomas-Krenn
Solid-State Drives (SSDs) are a frequently discussed topic in current IT infrastructures. In many cases the investment of replacing hard drives is taken on the assumption that SSDs are generally faster. But it depends on various parameters whether or not this assumption is true for a specific system. This talk will dive into the topics of I/O performance and discuss I/Os per second, throughput and latency. It will also present the Open Source performance suite TKperf which uses the Flexible I/O Tester (Fio) in the background. Covering the needs described above it brings performance testing to a next level. TKperf implements the tests specified in the SNIA “Solid State Storage (SSS) Performance Test Specification (PTS) Enterprise v1.0”, fulfilling all of its reporting requirements.

Conducting Defensive Information Warfare on Open Platforms - Ben Tullis, LinuxIT (Europe) Ltd.
The modern information security landscape is highly complex, multi-faceted and it evolves rapidly. It is therefore crucial for any information architect to ensure that sufficient care has been taken over the security of any system for which they are responsible. Ben Tullis takes an in-depth look at the subject of defensive information warfare, focussing well beyond the basics of patching and hardening and describing some of the more advanced techniques and tools that anyone can use to increase their levels of overall system visibility and thereby their confidence in its digital integrity. The key tools that are discussed are free, Open Source and run on GNU/Linux platforms, forming a vital element of an organization's information security infrastructure and thereby underpinning rapid, accurate and critical response to emergent security threats.

Notes on Taking KVM-on-KVM Nested Virtualization for a Spin - Kashyap Chamarthy, Red Hat
Nested Virtualzation involves three levels -- The physical host (L0), running a guest hypervisor (L1), and its associated 'nested' guest (L2). This is useful in several ways: a cloud user can get a guest hypervisor and can manage a variety of guests for development/test without the intervention of the cloud provider; enable live migration of hypervisors; ability to have an entire virtualization setup - a hypervisor and all its guests in a single virtual machine. Support for nVMX (Intel based Nested Virtualization) was first introduced around two years ago in KVM. Since then, there have been improvements in the Kernel, and also in the hardware space. This session discusses observations from recent testing of some workloads with upstream KVM with newest Intel hardware in a Linux-on-Linux environment. Finally, a glimpse of upcoming improvements in this space.

(Tutorial) Multi-layered Web Security with Linux - Konstantin Ryabitsev, The Linux Foundation
Robust web application security involves many layers -- from the operating system, to the web server, to the application code itself. This tutorial will look at most common web vulnerabilities (cross-site scripting, SQL, code and shell injections, cross-site request forgery, session hijacking, session fixation, etc), and offer best-practice advice on avoiding them in your web application. We will then investigate additional security tools available under Linux: SELinux to set up a strict sandbox around your webserver, mod_suPHP and Suhosin to help secure your PHP installations, and ModSecurity to help intercept web attacks before they even get to your application. Basic knowledge of HTTP and Apache is required.

Controlling Clouds: Beyond Safety - Gordon Haff, Red Hat
As an industry, we’ve mostly moved on from naive notions about cloud computing being inherently “safe” or “risky.” However, more sophisticated discussions require both greater nuance and greater rigor. This presentation takes attendees through frameworks for evaluating and mitigating potential issues in hybrid cloud environments, discusses key risk factors to consider, and describes some of the relevant standards and provider certifications. This is a broad and sometimes complex topic. However, it’s very manageable if individual risk factors are considered systematically and specifically.

Database deployments are getting increasingly complex spanning AWS, Openstack and on-premise datacenters. Before cloud solutions became available and reliable most deployments were carried out in private datacenters which had carefully configured hardware and network environments. In the cloud servers are deployed in minutes with very little consideration to where they are and how the networks are configured.We are now seeing more deployments that span multiple cloud providers and private data centres. Each of these providers have different ways of configuring compute and network resources.
