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.

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.

Solving the Package Problem - Joe 'Zonker' Brockmeier, Red Hat
In the beginning there was RPM (and Debian packages) and it was good. Certainly, Linux packaging has solved many problems and pain points for system admins and developers over the years -- but as software development and deployment have evolved, new pain points have cropped up that have not been solved by traditional packaging.

In this talk, Joe Brockmeier will run through some of the problems that admins and developers have run into, and some of the solutions that organizations should be looking at to solve their issues with developing and deploying software. This includes Software Collections, Docker containers, OStree and rpm-ostree, Platform-as-a-Service, and more.

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.

From MySQL Single Instance to Big Data - Morgan Tocker, Oracle
MySQL is the most popular database on the web but how do you grow from one instance on a single LAMP box to meets needs of high availability, big data, and/or 'drinking from the fire hose' without losing your sanity. This presentation covers best practices such as DRBD, read/write splitting, clustering, the new Fabric tool, and feeding Hadoop. 80% of Hadoop sites are fed from MySQL instances and it can be frustrating without guidance. MySQL's Fabric will manage sharding and provide more flexibility for your data. And using the memcached protocol to access data as a key/value pair can be up to 9 time faster than SQL (but you can still access the data concurrently with SQL). So do not get stuck without a plan for growth.

Getting Data Out of Your Cloud(s) With Open Source - Cody Herriges, Puppet Labs
Many Operations teams will find that at some point in time that a single cloud technology is not serving the business' needs and so they'll diversify. It is apparent fairly quickly that all these systems either have their own internal view of what it going on or have a complete lack of insight all together. To make a sound decision about where to invest your time and money you need to get all this usage and performance data into one place so it can be crunched and beautifully displayed.

Open source makes this possible by giving you a level of flexibility hard to find in other tools. We'll take a look at how we can instrument open source platforms like OpenStack and proprietary platforms: AWS and vSphere by utilizing the open source tools: ElasticSearch, Graphite, and Diamond.

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.

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.

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.

kpatch: Have Your Security And Eat It Too! - Josh Poimboeuf, Red Hat
System administrators are often expected to balance two opposing goals: security and convenience. If they want to maximize security and install kernel patches as soon as they're available, they may end up having to reboot the system frequently. But rebooting the system can be disruptive to many applications and users. As a result, system administrators are often forced to postpone kernel security updates, sometimes for long periods of time, leaving many systems vulnerable.

This talk introduces kpatch, a dynamic kernel patching infrastructure for Linux, which aims to resolve the conflict between security and convenience. Security patches can go from source code to patched kernel in minutes, without having to reboot or disrupt any applications. This makes both system administrators and their users happier!

PGP Web of Trust: How Does it Work? - Konstantin Ryabitsev, The Linux Foundation
All Public Key Cryptography (PKI) implementations rely on trust. Before Alice sends a secret message to Bob, she must trust that the public key she is about to use actually belongs to Bob, and not to Eve. PKI implementations such as x.509, which is the standard behind SSL, TLS and S/MIME, rely on centralized Certification Authorities (CAs), who issue digital certificates stating that Bob's key actually belongs to Bob. Putting all our trust in CAs has important flaws (hackers, governments,and frequently both), which is why another PKI implementation, OpenPGP, chooses to rely instead on a "Web of Trust," where each user builds up their own trust relationships from the ground up and therefore does not rely on any central authorities. This talk will shed a light on how the OpenPGP web of trust works, covering such topics as: the distinction of key trust from key validity; the difference between ultimately, fully, and marginally trusted keys; the importance of revocation certificates; the usefulness of delegated trust in larger organizations. Basic knowledge of public key cryptography is required.
