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

3. How this talk has started…. Ами… щом е за облачнитехнолологииняма да откажа…но нека да е с Node.js

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

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

7. 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

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

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

11. Comparing Node.js to .NET • Async Web Server Model Client Server Request Do Async Work Once event or asyncoperation is completethread completes the request Thread is free to service other requests Return from Async Response

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

13. Comparing Node.js to .NET • Mapping the Nomenclature

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

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

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

17. 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)

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

19. 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

20. 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.

21. Introduction to Node.js on Windows • Enabling a Node.js Server-Side App on Windows Azure (PaaS)

22. 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

23. 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

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

25. Azure SQL Database with Node.js • Microsoft Driver for Node.JS for SQL Server • Open First – hosted on Githubhttps://github.com/Azure/node-sqlserver • Simplicity by Design– keeps the simple API • Use in Windows Azure Web Sites

26. Azure SQL Database with Node.js • Connecting to SQL Server Database with Node.JS varsql = require('node-sqlserver'); varconn_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“

27. 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 (vari = 0; i < results.rows.length; i++) { res.write( "Description: " + results.rows[i][0] + "\n"); • } res.end(); }); }); // sql.open

28. Mobile Services & Node.js • JSON to SQL Type Mappings

29. Building a Web Site with Node.js • Node Options in the Gallery

30. Building a Web Site with Node.js • DEMO

31. Building and Deploying • No build needed • Deploy with Git (awesome)
