A walk through for improving overall operational effectiveness by building skills like statistics, software development lifecycle practices, graphing and metrics. This tutorial will focus on skill development and building better products.
One of the monitoring holy grails is knowing whether a system is behaving normally. This is usually considered a hard problem, but it can be done very cheaply at large scale. In this presentation I'll explain my definition of normality, several ways to quantify abnormality, and most importantly, what you can do with the results. There will be math, and I'll publish my slides.
As LinkedIn's traffic grew, it was clear the classical approach to load balancing would not grow with us. In addition to issues with scale, we found many missing key features along the way (cookie routing, DDoS protection, etc). This talk will cover the detail of our migration, things learned along the way, plugins/patches we contributed to ATS, and how other web properties can leverage them.

How gamedays at the Obama campaign led to an uneventful Election Day.
The real challenge of running an effective post-mortem is the complex, messy, all-too-human *feelings* of everyone involved. This talk gleefully tackles that challenge head on, and lays out effective techniques for helping a team to learn as much as possible after a public (and generally, pretty shameful) failure.
Velocity is about performance and operations - and the most high performing operations organizations practice both Devops and Continuous Delivery. This talk will show you how to successfully adopt both within your organization, supported by real-world examples of victory and defeat. Revolutionary change requires revolutionary behavior - this talk tells you how to win.
Being great at operations means much more than being technically competent.
To be truly successful you have to understand people. Every one of your teammates and everyone one of your customers is a person. And to get what you want, you have to build trust and meaning with those people.
Conference talks often cover how to measure, and improve services through dashboards. This talk aims to help the audience use personal metrics gathering and visualizations to reduce interrupts, improve self assessment and manage career growth.

Monitoring the performance of today's complex web applications over the coarse of the development is far from trivial. This talk discusses the emerging language tools designed for the new breed of web applications, ranging from syntax augmentation/transformation, advanced static and dynamic code analysis, as well as run-time complexity profiling.
While iframes have been the sandboxing method of choice by security folks, they haven't always had a good reputation for web performance. In this talk, we'll look at two techniques that use iframes to boost performance. The first is a method to load third party scripts without blocking the onload event, and the second makes updating far-future expiring content a cinch.

This talk will reveal key considerations for evaluating third-party vs. custom-built solutions, sharing how Intuit created a homegrown virtual device lab and automated testing to enable continuous integration that reduced mobile app test time.
The core infrastructure powering the web has seen significant performance improvements over the last few years. The browsers, devices, and networks are all much faster than they used to be, but has that resulted in a faster user experience?
In this talk, I will try to answer that question using real user measurement data from Google Analytics and Youtube.
A nearly infinite array of variables can affect performance. Gaining control over these variables allows providers and enterprises to introduce a greater degree of consistency and high performance into any environment. How can this be done? As infrastructure morphs into code, what was once secret becomes revealed.
Can your application scale with linear performance? Capacity planning for a Web or Mobile applications can be challenging but it is critical to any successful application launch. Testing how much load you can handle is just one part of it. Understanding where the bottlenecks are and what to do about it is just as important.
There is great progress on making web pages fast. Performance Management for native mobile applications is still in it's infancy. What if there was a free technology to help you solve the performance problems in your mobile applications?
