TSAR (the TimeSeries AggregatoR): How Twitter Counts 50+ Billion Daily Events in Real Time Using Open Source Technologies - Anirudh Todi, Twitter
Twitter's 250+ million users generate over 50 billion tweet views per day. Aggregating these events in real time - in a robust enough way to incorporate into our products - presents a massive scaling challenge. In this talk I'll introduce TSAR (the TimeSeries AggregatoR), a robust, flexible, and scalable service for real-time event aggregation designed to solve this problem and a range of similar ones. I'll discuss how we built Tsar from the ground up, almost entirely on open-source technologies (storm, summingbird, kafka, aurora, and others), and describe some of the challenges we faced in scaling it to process tens of billions of events per day.

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.

IPMI - Automatically Configuring (and Compromising) Large Server Deployments - Matthew Garrett, Nebula
The Intelligent Platform Management Interface (IPMI) is a specification allowing system managers to control and query system state without relying on the host operating system. At its most basic, this allows for remote power management of servers - at its most advanced, it provides full control over firmware configuration, sensor output and remote access to the installed OS.

This presentation will cover the advanced features provided by many server vendors and introduce a new vendor-neutral interface for configuration of systems, making building clouds easier than ever. It will also cover security considerations relevant to IPMI and describe the risks associated with any failure to design deployments with sufficient paranoia.

Large Scale Identification of Race Conditions (In OpenStack CI) - Joe Gordon, HP
Does your project have a CI system that suffers from an ever-growing set of race conditions? We have the tool for you: it has enabled increased velocity despite project growth.
Richard Stallman once said, “it turned out that debugging these asynchronous multithreaded programs was really hard.” With 30+ asynchronous services developed by over 1000 people the OpenStack project is an object lesson of this problem. One of the consequences is race conditions often leak into code with no obvious defect. To address this problem we have developed an ElasticSearch based toolchain called “elastic-recheck.” This helps us track race conditions so developers can fix them and identify when CI failures are related to the failed patch or are due to a known pre-existing race condition. elastic-recheck has saved countless hours while allowing us to better manage our race conditions.

Replicating from RDBMS into Hadoop - MC Brown, Continuent
Big Data and Hadoop in particular is currently big business, but one of the most significant problems is getting your data into Hadoop from your existing RDBMS stores. Whether you have user profile information, trades, or transactional information from your webstore in your RDBMS, analysing it often takes place within Hadoop. Dump and load techniques imply delays and intermittent replication. With Tungsten Replicator we can move data from multiple MySQL and Oracle databases directly into Hadoop giving you carbon-copies of your RDBMS data in real-time. In this presentation I'll demonstrate how the replicator achieves this including a live demo, and describe how it has helped Groupon and Booking with the data migration needs, and where we are headed in the future for supporting different tools and techniques for replication.

Security in the Cloud: Containers, KVM, and Xen - George Dunlap, Citrix Systems UK Ltd
In our interconnected world of mobile and cloud computing, particularly with the rise of governmental spying, corporate espionage, and theft of data by organized crime syndicates, security is more important than ever. Many claims are being made about the security of open-source cloud technologies: How can administrators, users, and developers separate fact from fiction?

This talk will equip the audience with the principles needed to evaluate security claims. We will talk the nature of risk, of vulnerabilities and exploits; the various factors that reduce the risk of vulnerabilities in software; and about TCB, threat models, and defense-in-depth.

We will then apply these principles to three open-source cloud technologies: containers, KVM, and Xen, to see how they stack up. These will be backed up with numbers: lines of code, security advisories, entry points, and so on.

The Evolution of Open vSwitch - Jesse Gross, VMware
Open vSwitch is the primary open source virtual switch used in next-generation datacenter deployments. It runs on both software and hardware switching platforms and has seen adoption by a wide variety of emerging technologies such as OpenFlow, OpenStack, and different forms of network virtualization.

As Open vSwitch has moved from a small project to production infrastructure, the expectations and requirements placed on it have radically evolved. The result is a balancing act - how can it support the stability and performance requirements of a data center, while still maintaining openness and flexibility to enable new technologies?

Starting with the original design goals of Open vSwitch, this talk will give some background on where we've been, the challenges and progress that's been made, and future directions.

Beating the Virtualization Tax for NoSQL Workloads With OSv - Don Marti & Glauber Costa, Cloudius
NoSQL data stores such as Cassandra and Redis are memory and CPU intensive loads which can have unacceptable performance when run under virtualization in production environments.

Over the past two years, the OSv project has profiled some of the important bottlenecks for NoSQL applications, and designed a new open-source guest environment to improve performance in key areas such as JVM memory allocation and network throughput.

The side effect of this performance work has been to move some difficult tuning tasks off the administrator's to-do list and into the guest OS where they can be handled automatically with better responsiveness.

Storage Tiering and Erasure Coding in Ceph - Sam Just, Red Hat
Ceph is designed around the assumption that all components of the system (disks, hosts, networks) can fail, and has traditionally leveraged replication to provide data durability and reliability. The CRUSH placement algorithm is used to allow failure domains to be defined across hosts, racks, rows, or datacenters, depending on the deployment scale and requirements. Ceph has introduced a storage tiering infrastructure and cache pools that allow alternate hardware backends (like high-end flash) to be leveraged for active data sets while cold data is transparently migrated to slower backends. The combination of these two features enables a surprisingly broad range of new applications and deployment configurations. This talk will cover a few Ceph fundamentals, discuss the new tiering and erasure coding features, and then discuss a variety of ways that the new capabilities can be leveraged.

This project is an attempt by one man to fix this large gap. Based on the Mesa internal hardware abstraction layer (Gallium3D) this project creates a virtio based GPU that can handle modern OpenGL and Direct3D requirements. The 3D rendering streams are passed to a renderer process in the host and it uses the local OpenGL interface to do the rendering. The project also encompasses a simple unaccelerated non-3D virtio gpu for situations where there is no local 3D hardware present.

Data Loading Survey Into Hadoop 2.0 - Douglas Liming, SAS Institute
What is the current state of loading “data” into Hadoop? What is the best way to load up Hadoop and feed the beast? How has Hadoop 2.0 changed the landscape of data movement and does YARN tie it all together? Taking a step beyond the command line -copylocalfile and we look at more than just Hive and HCatalog. Is the data affected at all? Why does the data appear to grow in size? What are the replication best practices around data movement and the modernization of the data lifecycle? This talk is a survey of data loading techniques and how Hadoop 2.0 impacts the modernization of data movement.

Migration Strategies from vSphere to Linux and OpenStack via a shared virtualized network - Dan Conde, Midokura
In this talk, Dan Conde will explore ways in which users who are considering migrating from a vSphere virtualization environment to a Linux and OpenStack-based environment can create a gradual migration strategy that enables co-existence of workloads in both environments with a gradual switchover, as opposed to an abrupt rip-and-replace conversion. Dan will examine ways in which a virtualized network environment can be used to develop both isolated and shared network segments to both environments to enable a smooth migration.

novm: Hypervisor Rebooted - Adin Scannell
Virtualization isn't only used to consolidate legacy hardware anymore; it runs the world's largest shared compute infrastructures. What if we reinvent the hypervisor for the cloud? Strong isolation, performance, and spin-up time matter -- not compatibility.

Over recent years, organizations have dramatically changed how they deploy and manage services, with Linux and virtualization at the center of the shift (AWS, OpenStack, etc.). Despite this, many developers and operators have minimal insight into how a hypervisor works or innovation possible at the bottom of the software stack.

The audience can expect a brief overview of virtualization fundamentals, followed by technical details of novm and specific insights gained during development, some straight-forward and others advanced. I hope that most developers will come away with new knowledge and curiosity, while advanced developers may be interested in some of the specific design decisions or roadblocks encountered.
