Full Cycle Developers at Netflix

The year was 2012 and operating a critical service at Netflix was laborious. Deployment frequency was measured in weeks. Operating a service involved staring at graphs and a lot of late-night heroics. Troubleshooting issues often devolved to bouncing the problem among teams. Today, in 2019, Netflix has grown to over 139M members enjoying our service all over the world. Deployments happen daily. The reliability of our service continues to improve and middle-of-the-night pages are rare. Our mission critical services are owned and operated by small teams of developers with no dedicated test teams and no dedicated operations teams. How did we make this transition? This talk presents Netflix's journey from siloed teams to our Full Cycle Developer model for building and operating services. I will discuss the various approaches we’ve tried, the motivations that pushed us to keep evolving, and the lessons learned along the way. Come learn about the Full Cycle Developer model, its pros and cons, and what’s required to make it work.

You Are Not A Commodity

The world of commodity engineering is coming to an end. Developers are becoming more productive, more flexible, and more entrepreneurial. How does this impact you as an engineer? And how does it impact large companies who need a fungible set of engineers to maintain their software?

Hacker vs Company, Cloud Cyber Security Automated with Kubernetes

Looking at the ongoing risks on any company today, no matter how much time and money you'll invest in cyber security as CISO or any security practitioner, You always arrive to same conclusion, it's not enough to achieve high standard of security, you have to do it 24/7 according to the changing cyber threats. In the talk we'll give a brief overview on different aspects of Cyber Security in the modern world, talking about Cloud and other external services that any size of a company uses now a days. We'll show from experience that the best and most fit approach is to achieve on going monitoring on your security posture. For the "why"? because the only thing that is a 100% sure, that the attack surface of every company is changing constantly, So we should keep on validating our security posture accordingly. And now the "How": We'll share how to build an infrastructure for security researchers that will allow them to concentrate on business logic and writing hacker “tasks”. Using Docker and Kubernetes on Google Cloud, these tasks can then be performed in parallel and without a lot of DevOps hassle. Our technique removes two common barriers: first, long and risky deployment processes and second, low transparency within the production system. Lessons learned promised and a glimpse of the Hackers view, because it's always interesting to see how you look from the outside.

Can Kubernetes Keep a Secret?

We’ve all experienced it: you’re working on a task, adding some code, and then you need to store some sensitive configuration value. It could be an API key, client secret or an encryption key ― something that’s highly sensitive and must be kept secret. And this is where things get messy. Usually, secret storage is highly coupled with how the code is deployed, and different platforms have different solutions. Kubernetes has a promise to simplify this process by using the native secret object, which, as the name implies, can be used to store secrets or sensitive configurations. Unfortunately, Kubernetes secrets are fundamentally broken, and a developer who tries to use them will definitely have some issues. But no need to worry ― there are solid alternatives for storing secrets securely on Kubernetes platform. One solution is to use Kamus, an open-source, git-ops solution, that created by Soluto, for managing secrets on Kubernetes. Kamus can encrypt a secret so it can be decrypted only by your app on runtime - and not by anyone else. The first part of this session will cover the challenges faced when using Kubernetes secrets (from a usability and security point of view). The second part will discuss some of the existing solutions (Sealed Secrets, Helm Secrets and others), their pros, and cons, and then feature Kamus: how it works, what problems it solves, how it differs from other solutions, and what threats it can help mitigate (and what threats it can’t). The talk will cover all that is required to know so you can run Kamus on your own cluster and use it for secret management. Join me for this session to learn how you can build a Kubernetes cluster than can keep a secret ― for real.

Data scientists are from Mars, software engineers are from Venus

Data scientists and software engineers come from different planets. Should the two species leave behind their differences in background, tools, behavior and emotions, or embrace them? In this talk, I'll review the path that a recorded sales call at Gong.io takes through various ML models, and will discuss our approach for creating, testing, deploying and monitoring ML models at scale.

Using Web Assembly with Web GL for interactive 3D apps

Web Assembly is an exciting new technology supported by modern browsers, that aims to execute computations at native speed in the browser. At Align Technology we are in the process of enhancing our WebGL 3D visualization apps with new interactive features that have so far been available only on native C++ applications due to performance requirements. We take existing C++ geometric algorithms and compile into WASM modules, which we load dynamically into our WebGL apps, using Web workers to run the heavy computations in the background. We will demonstrate some of the tools, share what we have learned in this journey, and explain the benefits and tradeoffs in this technology.

Like A Surgeon - Dissecting a completely Functional-Reactive JavaScript app for the very first time

Today we have the ability to write fully Functional-Reactive code in JavaScript, using RxJS. However, in our day-to-day life we often use RxJS alongside other libraries and patterns that make our life easier, but also distance us from pure Functional-Reactive Programming (FRP). What would an app that has been written completely in RxJS, and in-line with the principles of FRP, look like? In this talk we will examine such an app, and use it to understand what truly functional-reactive code in JavaScript looks like, and what are the principles that underlie it.

How Serverless Lets You Turn Massive DevOps Workflows Into One-Click-Wonders

Mobile at Scale with React Native - Wix Multi-Module Architecture

At Wix.com we are building our mobile app with React Native from the first commit, we started working with React Native three years ago and today we are one of the biggest projects written with React-Native. We are 72 mobile developers, from 15 different teams, writing code that is integrated into one mobile app and we are able to release a production version almost every day. Scaling a production-grade application without compromising on performance and dev velocity, drove us to think more like an OS to allow each team easily integrates their module into the main Wix’s React Native mobile app. In this talk, we'll try to stand on the basic rules for building a modular scalable mobile application, following that we will review React Native's main concepts, understand it's architecture and see how it fits with multi-module architecture concepts at Wix. We will summarize with the real cost-benefit of React Native, covering the benefits of this framework but also the challenges it brings.
