Azure talk for NUS

Transcript

1. WINDOWS AZURE HACKING OUT WEBAPPS HOW TO GET STARTED, AND WHAT YOU NEED TO GET GOING by & Laurence Putra Divyanshu Arora
2. WHAT THIS TALK IS NOT A step by step guide to click buttons on the Azure portal. A guide to using x, y, or z web development framework.
3. BUT RATHER A BUNCH OF STUFF you would need to do to get started with your own linux servers to host your webapp
4. LINUX?!?!?! Yep, you read it right. We'll be using CentOS for this demo.
5. QUICK POLL 1. How many of you here have laptops? 2. Who here knows how to use linux? 3. Who here has their own website? 4. Who maintains their own server and hosts sites for themselves and/or other people?
6. FOR THOSE WHO HAVE LAPTOPS Go to Free 3 month trial on a small instance 1. 1 dedicated core 2. 1.75 GB RAM 3. Free phone support 4. In Singapore: 1800 622 1283 Go on, sign up, and spin up a server bit.ly/azureSG
7. WHY A VM ON A CLOUD SERVICE? WHY NOT A DEDICATED SERVER? OR A PAAS SERVICE LIKE HEROKU? tl;dr-it's a balancing act between advantages of abstraction layers Extremely easy setup, trivial scaling, etc. Configurability, determinism in performance, etc. Services like Azure, EC2, etc., imo, a sweet spot
8. WHY AZURE Because they have some really good features Bunch of *easily usable* stuff like georeplication high availability free phone support
9. INTRODUCING LAMP 1. Linux 2. Apache 3. MySQL 4. Php A stack, that's moderately easy to set up, for you to start working on something right away
10. LINUX INITIAL SETUP After you ssh into your server Copy your public key into the authorized_keys file Allows you to login to your server with better security than a simple password But recommended that you password protect your private key mkdir ~/.ssh vim ~/.ssh/authorized_keys chmod go-w ~/.ssh chmod 600 ~/.ssh/authorized_keys
11. COMMANDS YOU'LL USE VERY OFTEN ls ./ cd ../ pushd, popd rm -rf / mkdir touch vim grep blah man
12. OTHER UNIX-Y STUFF YOU SHOULD KNOW | ls | grep NUS > ls > filelist >> ls >> filelist
13. INSTALLING SOFTWARE CentOS/Fedora uses the yum package manager Debian/Ubuntu uses apt-get package manager Same purpose, just different tools on different systems yum install app-name yum remove app-name yum -C search app-name yum update
14. APPS REQUIRED TO RUN YOUR WEBSITE sudo yum install httpd php mysql mysql-server php-mysql
15. APACHE (HTTPD) Server software In charge of responding to the browsers Default root: Manage multiple sites on a single machine using virtualhosts chkconfig httpd on service httpd start
16. VIRTUALHOSTS your-domain.conf Put in in a directory and include that directory in <VirtualHost *:80> ServerAdmin you@your-domain.com DocumentRoot /users/you/your-domain.com ServerName your-domain.com ServerAlias www.your-domain.com </VirtualHost>
17. MYSQL WHAT IS IT? A database Used to store data Other databases out there include PostgreSQL, mongoDB
18. WHY USE A DATABASE? WHY NOT JUST STORE IN A FILE? Database supports indexing Allows you to search for records Think of the database as a giant excel spreadsheet that allows you to retrieve information really quickly
19. PHP A scripting language that allows you to generate websites Can do a whole bunch of other stuff, including processing your data, and basically works like any other programming language
20. COUPLE OF STUFF YOU NEED TO KNOW $blahblah is a variable scripts start with <?php scripts end with ?>
21. CODE SAMPLES foreach if/else foreach ($variable as $value) { $total = $total + $value; $count++; } if ($condition) { //do something } else { //do something else }
22. HELLOWORLD.PHP displays <?php echo "Hello World" ?>
23. MORE COMPLICATED STUFF Stuff like websites you see around You have to learn HTML too. And to create stuff like this presentation You'll need Javascript as well
24. DEMO
25. COUPLE OF OTHER STUFF Denyhosts newrelic Mixpanel
