Introduction: Aditya Agarwal, Director of Engineering at Facebook, gave an excellent  Scale at Facebook talk that covers their architecture, but the talk is really more about how to scale an organization by preserving the best parts of its culture. The key take home of the talk is:  You can get the code right, you can get the products right, but you need to get the culture right first. If you don't get the culture right then your company won't scale. This leads into the four meta secrets of scaling at Facebook: Scaling takes Iteration Don't Over Design Choose the right tool for the job, but realize that your choice comes with overhead. Get the culture right. Move Fast - break things. Huge Impact - small teams. Be bold - innovate. Some Background  Facebook is big : 400 million active users; users spend an average of 20 minutes a day; 5 billion pieces of content (status updates, comments, likes, photo uploads, video uploads, chat messages, inbox messages, group events, f

5 In Facebook users can't be partitioned because users can join any network. [sent-16, score-0.186]

6 Every new user can access any other user's data which means there's no way to partition users by geography, or any other metric. [sent-18, score-0.178]

14 If you don't get the culture right then your company won't scale. [sent-68, score-0.783]

15 This is a particular instance, but the most important thing is the culture, getting people to believe that the most important thing is how quickly they can move. [sent-75, score-0.281]

16 Get the right set of people, empower them, and let them work. [sent-79, score-0.281]

17 If you can't push responsibility down and you isolate the number of people who feel they are real owners, then the only people you'll be able to motivate are the people who think they are the real owners. [sent-89, score-0.567]

18 Isolate the part of the culture that you value and want to preserve. [sent-91, score-0.353]

Scaling Takes Iteration . You can say that again. Don’t Over-Design . Just use what you need as you scale your system out.

Introduction: Robert Johnson,   a director of engineering at Facebook, celebrated Facebook's monumental achievement of reaching 500 million users by sharing the scaling principles that helped  reach that milestone. In case you weren't suitably impressed by the 500 million user number, Robert ratchets up the numbers game with these impressive figures: 1 million users per engineer 500 million active users 100 billion hits per day 50 billion photos 2 trillion objects cached, with hundreds of millions of requests per second 130TB of logs every day How did Facebook get to this point? People Matter Most . It's people who build and run systems. The best tools for scaling are an engineering and operations teams that can handle anything. Scale Horizontally . Handling exponentially growing traffic requires spreading load arbitrarily across many machines. Using different databases for tables like accounts and profiles only doubles capacity.

Introduction: It remains that, from the same principles, I now demonstrate the frame of the System of the World. -- Isaac Newton The practice of IT reminds me a lot of the practice of science before Isaac Newton. Aristotelianism was dead, but there was nothing to replace it. Then Newton came along, created a scientific revolution with his System of the World . And everything changed. That was New System of the World number one. New System of the World number two was written about by the incomparable Neal Stephenson in his incredible  Baroque Cycle  series. It explores the singular creation of a new way of organizing society grounded in new modes of thought in business, religion, politics, and science. Our modern world emerged Enlightened as it could from this roiling cauldron of forces. In IT we may have had a Leonardo da Vinci or even a Galileo, but we’ve never had our Newton. Maybe we don't need a towering genius to make everything clear? For years startups, like the frenetically inventive

Introduction: Real-time social graphs (connectivity between people, places, and things). That's why scaling Facebook is hard says Jeff Rothschild , Vice President of Technology at Facebook. Social networking sites like Facebook, Digg, and Twitter are simply harder than traditional websites to scale. Why is that? Why would social networking sites be any more difficult to scale than traditional web sites? Let's find out. Traditional websites are easier to scale than social networking sites for two reasons: They usually access only their own data and common cached data. Only 1-2% of users are active on the site at one time. Imagine a huge site like Yahoo. When you come to Yahoo they can get your profile record with one get and that's enough to build your view of the website for you. It's relatively straightforward to scale systems based around single records using distributed hashing schemes . And since only a few percent of the people are on the site at once it takes comparatively little

Introduction: One of the premier scaling strategies is always: get someone else to do the work for you. But unlike Huckleberry Finn in Tom Sawyer , you won't have to trick anyone into whitewashing a fence for you. Times have changed. Companies like Ning , Facebook , and Salesforce are more than happy to help. Their price: lock-in. Previously you had few options when building a "real" website. You needed to do everything yourself. Infrastructure and application were all yours. Then companies stepped in by commoditizing parts of the infrastructure, but the application was still yours. The next step is full on Borg take no prisoners assimilation where the infrastructure and application are built as one collective. What you have to decide as someone faced with building a scalable website is if these new options are worth the price. Feeding this explosion of choice is one of the new strategy games on the intertubes: the Internet Platform Game. Ning's Marc Andreessen defines a platform as: a

Introduction: Facebook has been teasing us. While many of their recent acquisitions have been surprising, shocking is the only word adequately describing Facebook's 5 day whirlwind acquisition of Oculus , immersive virtual reality visionaries, for a now paltry sounding $2 billion. The backlash is a pandemic, jumping across social networks with the speed only a meme powered by the directly unaffected can generate. For more than 30 years VR has been the dream burning in the heart of every science fiction fan. Now that this future might finally be here, Facebook’s ownage makes it seem like a wonderful and hopeful timeline has been choked off, killing the Metaverse before it even had a chance to begin. For the many who voted for an open future with their Kickstarter dollars , there’s a deep and personal sense of betrayal, despite Facebook’s promise to leave Oculus alone. The intensity of the reaction is because Oculus matters to people. It's new, it's different, it create

Introduction: In update to Prismatic Architecture - Using Machine Learning on Social Networks to Figure Out What You Should Read on the Web , Jason Wolfe, even in the face of deadening fatigue from long nights spent getting their iPhone app out, has gallantly agreed to talk a little more about Primatic's approach to Machine Learning. Documents and users are two areas where Prismatic applies ML (machine learning): ML on Documents Given an HTML document:  learn how to extract the main text of the page (rather than the sidebar, footer, comments, etc), its title, author, best images, etc determine features for relevance (e.g., what the article is about, topics, etc.) The setup for most of these tasks is pretty typical. Models are trained using big batch jobs on other machines that read data from s3, save the learned parameter files to s3, and then read (and periodically refresh) the models from s3 in the ingest pipeline. All of the data that flows out of the system can be
