Cloud Architecture

NODEJS

AWS EC2 MongoDB

Development Stack

• AWS EC2

• NodeJS (with CoffeeScript)

• MongoDB

• Git

• Sublime Text2

• Grunt

• Jenkins

AWS EC2

• Elastic compute cloud web service

• Free Tier for the first year

• Need to be familiar with command line

NodeJS highlights

• Uses JAVASCRIPT

• Event-driven

• Non-blocking

• NodeJS Package Management Tool: NPM

• Big open source community

Why NodeJS?• Streamlines backend/frontend development

• Best for (soft) real-time web application

• Natively compatible with JSON

• Can be a web container itself

• Scalable

Why not NodeJS

• Still in early development age

• Not enough high-level abstraction library

• CPU intensive jobs

Resources

Commonly Used Libraries

• ExpressJS / MeteorJS

• PassportJS

• Mocha

• Async

• Mongoose

• node-inspector

• nodemon

• forever

CoffeeScript

• Compiles into javascript

• Write less, do more

• Easier class, inheritance

• Source Map Support (new!)

MongoDB Highlights

• Document Based

• High Availability

• Scalability

• Data stores in BSON format

• Javascript-like function call

Why MongoDB?

• Big Data

• Dynamic Schema

• Real-Time

• Geospatial Capabilities

• Easy to scale (Sharding/Replica/HA)

Why Not MongoDB?

• Atomic transactions only at document level

• No complex querying (e.g. no join)

• Data size higher

• Needs more RAM for indexing

Git

• Distributed version control

• Github / Bitbucket

• Working offline

• Collaboration

Sublime Text2

• Text editor for Programmers

• Syntax highlights for various languages

• Code autocompletion

• Plug-ins (git, coffeescript, emmet)

• Flexible layout

Grunt

• Javascript task runneraka. automation/build tool

• minification / compilation: uglifyjs

• unit testing: mocha

• validation: jslint

• documentation: docco

• deploy

Jenkins

• Continous Integration Server

• Build newest code periodically

• Run Tests & Code Analysis

Working with Mobile

• Divide and Conquer
