Node.js + AWS @davidfalck

*  LinkedIn’s entire mobile software stack is completely built in Node

*  Why? Scale. *  Huge performance gains compared to what they were

using before (Ruby on Rails) *  Went from running 15 servers with 15 instances (virtual

servers) on each physical machine, to just four instances that can handle double the traffic.

Why the Node.js Buzz?

*  Javascript platform based on Google Chrome V8 JS Engine

*  Ryan Dahl (Joyent) *  Event-‐driven, non-‐blocking I/O model to allow your

applications to scale while keeping you from having to deal with threads, polling, timeouts, and event loops

*  FAST *  Used for real-‐time, data-‐intensive apps (mobile!)

*  POPULAR

What is Node.js ?

Node.js on GitHub

var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-‐Type': 'text/plain'}); res.end('Hello World\n'); }).listen(1337, '127.0.0.1');

Hello World

*  Thread-‐based networking is inefficient and difficult *  Node shows much better memory efficiency under high-‐

loads than systems which allocate 2mb thread stacks for each connection.

*  Users of Node are free from worries of dead-‐locking the process (*there are no locks*)

*  Almost no function in Node directly performs I/O, so the process never blocks.

*  Because nothing blocks, less-‐than-‐expert programmers are able to develop fast systems

What makes Node.js so fast?

Under the Node.js hood

Javascript?

Under the Node.js hood

*  Javascript! *  Platform independent *  Easy to use *  Ubiquitous

*  Google Chrome’s V8 Javascript Engine *  Translates JS into machine code (not interpreted)

When not to use Node.js

*  Node.js is not ideal for CPU intensive jobs like sorting, transformations, number crunching, analytics… *  Traditional CRUD web apps that need to be highly concurrent, performance degradation will occur when the data is needed to be transformed… *  You can offload processing to another language that is better at making use of the CPU *  Cultural fit? Too new? You decide…

*  Dec 6th: AWS released developer preview of node.js libraries to access AWS: *  DynamoDB *  S3 *  EC2 *  SWS

*  Allows you to manage parallel calls to several AWS web services

Node.js + AWS

*  Azure *  Joyent *  EngineYard *  Heroku

Node.js + Other Clouds

*  http://nodejs.org *  http://en.wikipedia.org/wiki/Nodejs *  http://aws.typepad.com/aws/2012/12/aws-‐sdk-‐for-‐nodejs-‐now-‐available-‐in-‐preview-‐form.html *  http://www.jamesward.com/2011/06/21/getting-‐started-‐with-‐node-‐js-‐on-‐the-‐cloud/ *  http://venturebeat.com/2011/08/16/linkedin-‐node/

Big Data in the Cloud

A Journey into the unknown

Who Jellyvision is and why are analy9cs important to us

•  We create interac9ve experiences –  Desktop – Mobile

•  … which ask ques9ons, inform people, generate leads •  “Virtual Advisors” •  We also collect analy9cs in real 9me to generate reports

about: –  How people answered a ques9on –  Where they dropped out –  Lots of impressive stats!

The Problem

•  Longer term projects and high volume projects causing MySQL to bust at the seams

•  Some types of reports taking too long, or causing MySQL to crash if we include too much data

•  In all fairness, we could probably tune MySQL, throw it on bigger servers, more memory

•  Diminishing returns •  MySQL is fine for collec9ng the data…

The Solu9on

•  Hadoop! •  Why Hadoop? Lots of possibili9es out there, but which one to use? Cassandra, CouchDB, Hadoop, Membase, MongoDB, Neo4j, …

•  Big Data meetups tended to have lots of people using Hadoop

•  And I knew others using it. •  And Hortonworks had a fancy point and click solu9on I could use to get started quickly

Op9ons with op9ons

•  Now that I picked Hadoop, I had several op9ons, and op9ons within op9ons to use to analyze my data: – Hive, Pig, MapReduce, Java, R

•  I knew Java •  MapReduce seemed to make sense •  I’ll probably play with Hive and Pig next

It’s All About The Data

•  Visit data •  Event data •  Denormaliza9on of data •  Generated a ton of fake data: – Started with 600K visits, 3M events – Moved up to 1.8M visits, 60M events

Make it so •  First experience: Hortonworks Virtual Sandbox

–  Single node AMI at Amazon –  Hadoop 1.0 –  600K visits, 3M events

•  On our exis9ng placorm we needed to break reports up into smaller chunks for some data because MySQL could not handle it.

•  Results! What would have taken hours, took only 5 minutes on a single node Hadoop "cluster”

•  In reality, some of the queries I could also run with command-‐line tools (wc, grep, awk) on the data considerably faster than even Hadoop.

•  Important lessons learned so far: –  Think outside the RDBMS: they are great, but it may not make sense

for all types data

Looking at more real data •  Now, lets generate data that is much closer to some of our product •  Instead of one ques9on and answer, how about 15 ques9ons? Add

in some other events gives a total of 34 events. •  Throw in some people returning, some of them mul9ple 9mes •  Throw in some people who don't start the conversa9on, etc. •  Run my lijle auto-‐data-‐generator and BOOM! 20 million events

and 4.4GB later I have my data… •  … which took up too much disk space to run on the demo system I

was using. Might as well turbo-‐charge this puppy...

More disk space!

•  Full install of Hadoop (Hortonworks HDP) •  Single node •  600K visits, 20M events – 6m 29s, ~30s aner map phase completed

•  1.8M visits, 60M events – 18m 3s, ~90s aner map phase completed

More nodes

•  3 nodes: 11m •  4 nodes: 9m 16s •  Yay! Nodes!

Caveats

•  Not using Hadoop to its fullest / basically a weekend job

•  Algorithms employed in this example probably won't end up it a book alongside Knuth’s

Next steps

•  Make sure results on real data lines up •  Integrate with team to generate reports they need

End stuff

•  Thanks to the folks at Hortonworks who answered my fran9c and spas9c ques9ons.

Keep Your Control.Private Cloud with Karl Zimmerman, CEO of Steadfast.

Private Cloud:What do we mean?

Private cloud is a form of cloud computing where the customer has some control/ownership of the service implementation. It is a scalable, elastic IaaS solution based on cloud computing but with more control over resources.

Private Cloud:What are the advantages?

Security

Availability

No vendor lock-in

Ease of management

Private Cloud:Security

Dedicated & segregated resources

More options to integrate with existing security

Private Cloud:Availability

Understanding and control of the infrastructure

Get the resources you need, when you need them

You're not subject to the whims of other users

Private Cloud:Vendor Lock-In

No "secret sauce."

Utilize true open source

Private Cloud:Management

Easier to find employees with general IT knowledge

Utilize a broader array of tools and software

Get support/assistance from multiple levels

Private Cloud:To Summarize

Private cloud can deliver what you need out of a public cloud, but giving you more control. Losing control over security, availability and issues like vendor lock-in and management vanish into thin air like, well, a cloud. And the fact that it doesn’t have to cost you more is a plus, too.
