Node js - Enterprise Class
Download as PPTX, PDF5 likes3,073 views
Node.js is gaining significant interest for building scalable web applications. Several large companies like LinkedIn, eBay, and Walmart are using Node.js in production for its performance and scalability benefits when handling input/output bound workloads. Node.js allows non-blocking event-driven programming which helps simplify building applications that interact with services, databases, and handle many concurrent connections using little memory. Its large ecosystem of open-source modules also helps speed up development.
Node js - Enterprise Class
- 3. Node, GAINING A LOT OF INTEREST
- 4. NEW JOBS are exploding
- 7. AND NPM IS OUTTA CONTROL 2011... ~1800 projects 730 active package authors 26 npm contributors version 1.0 released
- 8. AND NPM IS OUTTA CONTROL 2012... 72 npm contributors version 1.1.35 released
- 9. WHY???
- 11. LINKEDIN: Node drives the mobile stack “On the server side, our entire mobile software stack is completely built in Node,” KIRAN PRISAD
- 14. SCALE “One reason was scale.” KIRAN PRISAD
- 15. Great for io/bound cals “The second is, if you look at Node, the thing it’s best at doing is talking to other services.” KIRAN PRISAD
- 16. Great for io/bound cals “The mobile app has to talk to our platform API and database. We’re not doing massive data analytics.” KIRAN PRISAD
- 17. Huge perf gains “Node showed us huge performance gains compared to what we were using before, which was Ruby on Rails.” KIRAN PRISAD
- 19. QL.io (EBAY): HTTP gateway a declarative, evented, data- retrieval and aggregation gateway for HTTP APIs SUBBU ALLAMARAJU
- 22. What was important • Performance and scale for i/o bound workloads • Operability • Low per-connection memory overhead SUBBU ALLAMARAJU • Dynamic language support
- 23. Fast interations “Javascript and node.js allowed us to iterate very rapidly.” SUBBU ALLAMARAJU
- 24. rich ecosystem “Though we were initially concerned about finding the right tools and libraries, the node.js ecosystem proved sufficient for us to build as complex a system as ql.io.” SUBBU ALLAMARAJU
- 25. SuperB scale “We were able to tune a regular developer-quality Ubuntu workstation to handle more than 120,000 active connections per node.js process, with each connection consuming about 2k memory.”SUBBU ALLAMARAJU
- 26. Non BLOCKING / simplified programming model “Node’s evented I/O model freed us from worrying about locking and concurrency issues that are common with multithreaded async I/O.” SUBBU ALLAMARAJU
- 28. Walmart: mobile strategy In a nutshell, Walmart is able to serve some very sophisticated features to mobile users on the client side using Node. DION BEN ALMAER GALBRAITH
- 30. Walmart: BETter expErIENCe “It’s saving mobile shoppers a ton of time by customizing content based on device type and browser capabilities.” DION BEN ALMAER GALBRAITH
- 31. Javascript everywhere progressive enhancement “We’ve been fascinated for a long time by end-to-end JavaScript,” …“a website that would be rich and dynamic… on devices that weren’t too powerful.” DION BEN ALMAER GALBRAITH
- 32. Javascript everywhere progressive enhancement “Now, on Walmart’s re-engineered Node- powered mobile app, all the front-end code gets executed on the back end.” DION BEN ALMAER GALBRAITH
- 33. Scale and flexibility “We rely on services all over the world…We do not control all of those services.” DION BEN ALMAER GALBRAITH
- 34. Scale and flexibility “Node allows us to front all these services… and scale up very nicely. It’s perfect for what we’re doing in mobile.” DION BEN ALMAER GALBRAITH
- 37. Turner: Disruptive Thinking “At Turner, Node.js represents a disruption to the mainstream thinking around how you build applications.” DON BROWNING
- 38. Turner: Disruptive Thinking “We found developers were over- engineering their code; writing code for the sake of writing code. We needed to shake things up.” DON BROWNING
- 39. Turner: Startup Mentality “We’re also starting to behave more like a startup, rather than an enterprise shop. Quick turn around, no ceremony, and finding the Minimum Viable Product.” DON BROWNING
- 40. Turner: Startup Mentality “We’ve found that being a part of the open-source community really facilitates this mindset.” DON BROWNING
