How this talk has started…. Боби, хайде да направим една презентация за Microsoft Azure

How this talk has started…. Ами… щом е за облачни технолологии няма да откажа… но нека да е с Node.js

How this talk has started…. А защо да не е за open source технологии в Microsoft Azure ? Да включим и други технологии ?

How this talk has started…. Ето така се правят презентации…

What is Node.js Node.js is a simple but powerful tool for asynchronous network programming By utilizing your existing knowledge of JavaScript, you can get up and running Apps quickly Node.js is based on V8 JS engine Practically no installation required Very lightweight (one 7MB static exe) Node.js encourages good software practices out of the box like async programming and inversion of control

Comparing Node.js to.NET Traditional Web Server Model ClientServer Request Response Dedicated Thread to service request

Comparing Node.js to.NET Traditional Web Server Model Request 1 thread 1 processes the request and blocks till completion Response 1 thread 1000 processes the request and blocks till completion Web Server (with 1000 threads) Request 1000 Response 1000 Request 1001 Request 1002 Request 1003 Requests queue up as blocked threads wait on server

Comparing Node.js to.NET Async Web Server Model ClientServer Request Response Thread is free to service other requests Return from Async Do Async Work Once event or async operation is complete thread completes the request

Comparing Node.js to.NET Async Web Server Model Web Server Request 1 Request Single threaded event Loop Listen for requests Starts any I/O operations by specifying a call back to execute on completion Continue to listen for requests Response 5 Response 1 “With node.js everything runs in parallel Except your code ! ” Response 99999

Introduction to Node.js on Windows How Node.js works?

Introduction to Node.js on Windows Node is Single Threaded!

Introduction to Node.js on Windows FAST..but, Node is FAST!

Introduction to Node.js on Windows How Node.js works? Asynchronous I/O Event Loop with Pool of Threads Dead-Lock Free (no concurrency issues)

Introduction to Node.js on Windows How Node.js works?

Introduction to Node.js on Windows Why Node.js The good parts of JavaScript are really awesome One language for the browser and the server Async by default Over 1M concurrent requests

Introduction to Node.js on Windows Enabling a Node.js Server-Side App on Microsoft Azure (PaaS) Web Role - all requests are received by Microsoft IIS 7 and passed to a native IIS module called iisnode Worker roles are much more like the basic node application in that they directly run node.exe for Server.js when the role instance starts.

Introduction to Node.js on Windows Node.js in Azure Websites The architecture for running Node.js within Azure Websites is identical to that used when hosting within a Web role

Introduction to Node.js on Windows Integrating Node with IIS / Benefits of using IISNode: Run your Node application across multiple CPU cores Serve static content from IIS, dynamic content from node Integrated, browser-based debugging with node- inspector Monitor the node executable plus changes to your code Configuration flexibility with XML + YAML overrides View console logs from the browser All the other existing IIS benefits, including output caching

Azure Storage with Node.js Azure Storage Blob Storage Table Storage Queue

Azure SQL Database with Node.js Microsoft Driver for Node.JS for SQL Server Open First – hosted on Github sqlserver sqlserver Simplicity by Design – keeps the simple API Use in Windows Azure Web Sites

Azure SQL Database with Node.js Connecting to SQL Server Database with Node.JS var sql = require('node-sqlserver'); var conn_str = "Driver={SQL Server Native Client 11.0};" + "Server=tcp:[databasename].database.windows.net,1433;" + "Database=TaskList;Uid=[username];" + "Pwd=[password];Encrypt=yes;Connection Timeout=30“

Azure SQL Database with Node.js Connecting to SQL Server Database with Node.JS sql.open(conn_str, function (err, conn) { err && throw err; conn.queryRaw(query, function (err, results) { err && throw err; for (var i = 0; i < results.rows.length; i++) { res.write( "Description: " + results.rows[i][0] + "\n"); } res.end(); }); }); // sql.open
