14. And the enterprise?
15. BEWARE! Shameless Plug ahead!
16. CLOUD
17. Ok, so there are some others at it too...
19. Building SaaS Apps
20. Deploy to the Cloud
22. Cloud Hosting Platforms You can get a free AWS instance for a year. Heroku apps are free to start off. Windows Azure is available free to many people - as students you probably have access to free Azure accounts. Linode virtual servers can be provisioned in seconds for $20/month. Digital Ocean provide 512MB virtual servers for only $5/month.
23. What about the tech?
24. Build for the Web (and for Mobile) The Web is the main platform for SaaS applications. Of course, most SaaS apps are also mobile-ready.
25. Web Application Architecture Client Side HTML(5) CSS(3) JavaScript DOM Libraries MVC Libraries Templating JSON Server Side Database Application Server Server-side Frameworks 3rd party APIs Sockets OAuth Security
26. CoreHR Example Last Wednesday, we built a real-time video interview app in one day. Peer-to-peer video conferencing Real-time chat File sharing Candidate profile information Compare with other candidates And more.
27. CoreHR Example - Tech Used HTML5 CSS3 JavaScript WebRTC Web Sockets Node.js Oracle Database WebLogic App Server PL/SQL JSON ExtJS XTemplates
29. Node.js We’ve seen how to build client-side apps using JavaScript. Node.js brings JavaScript to the server-side. It’s great for building real-time communication applications (chat, video conferencing, file sharing)
30. A Video & Text Chat Server in Node.js var  app  =  require('express')(); var  server  =  require('http').createServer(app); var  webRTC  =  require('webrtc.io').listen(server); var  port  =  process.env.PORT  ||  8080; server.listen(port); webRTC.rtc.on('chat_msg',  function(data,  socket)  {   var  roomList  =  webRTC.rtc.rooms[data.room]  ||  [];   for  (var  i  =  0;  i  <  roomList.length;  i++)  {     var  socketId  =  roomList[i];     if  (socketId  !==  socket.id)  {       var  soc  =  webRTC.rtc.getSocket(socketId);       if  (soc)  {         soc.send(JSON.stringify({           "eventName":  "receive_chat_msg",           "data":  {             "messages":  data.messages           }         }),  function(error)  {});       }     }   } });

37. GitHub Pricing Example
38. GitHub Enterprise Pricing 20 users = $5,000/year 40 users = $10,000/year 80 users = $20,000/year 320 users = $80,000/year 500 users = $125,000/year 3,000 users = $750,000/year
