1. WINDOWS AZURE MEET YOUR VM HOW TO GET STARTED, AND WHAT YOU NEED TO GET GOING by & Laurence Putra Ruiwen Chua
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. PREFLIGHT Laptops? Linux? Azure?
5. AZURE Go to Free 3 month trial on a small instance 1 dedicated core 1.75 GB RAM Free phone support In Singapore: 1800 622 1283 Go on, sign up, and spin up a server Let's use Ubuntu 12.04 bit.ly/azureSG
6. THE CLOUD 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., a sweet spot
7. WHY AZURE Because they have some really good features Bunch of *easily usable* stuff like georeplication high availability free phone support a really clean interface
8. INTRODUCING LAMP Linux Apache MySQL Php A stack, that's moderately easy to set up, for you to start working on something right away
9. LINUX INITIAL SETUP After you ssh into your server Copy your public key into the a u t h o r i z e d _ k e y s file Allows you to login to your server with better security than a simple password But recommended that you password protect your private key m k d i r ~ / . s s h v i m ~ / . s s h / a u t h o r i z e d _ k e y s c h m o d g o - w ~ / . s s h c h m o d 6 0 0 ~ / . s s h / a u t h o r i z e d _ k e y s
