WEBVTT 00:00.860 --> 00:03.670 I want you to pretend for a minute that I'm a programmer. 00:03.830 --> 00:06.500 No I'm not just a programmer I'm a developer. 00:06.500 --> 00:12.740 I've got an idea for a new kind of web application that everybody's going to go crazy over the next 00:12.770 --> 00:13.510 Dropbox. 00:13.520 --> 00:18.060 It's it's it's the next G-mail I don't know but I love this thing. 00:18.170 --> 00:19.990 Now keep in mind that I'm a programmer. 00:20.030 --> 00:20.550 OK. 00:20.690 --> 00:22.260 And that's what I do. 00:22.310 --> 00:24.700 I write programs and I've got this dream. 00:24.770 --> 00:30.980 But for me as a programmer to go through the process of setting this up I have to be setting up servers 00:30.980 --> 00:36.950 and I'd have to have lots of administrators to protect all my systems and people running backups and 00:37.220 --> 00:41.500 then I would need people grabbing stuff for me help and my development didn't need this. 00:41.540 --> 00:46.790 It's a big deal for somebody like me to get my dream out there. 00:46.790 --> 00:52.920 Wouldn't it be cool if we could create a magic little world where me as a programmer. 00:52.940 --> 01:00.890 All I see is a a platform a basically a screen that allows me to write my code and not only write my 01:00.890 --> 01:07.880 code but have access to big software libraries that I need to help write my code that will help keep 01:07.880 --> 01:10.070 track of my development for me. 01:10.190 --> 01:15.260 And then when I got it and I want to see how it works all I can do is press a button and say deploy 01:15.260 --> 01:20.450 and it magically appears on a server that's completely configured and ready to go at all I have to do 01:20.450 --> 01:22.110 is type in w w w that. 01:22.130 --> 01:25.350 Check out my cool site dotcom and see how it's do it. 01:25.610 --> 01:26.660 Sounds fun. 01:26.900 --> 01:34.520 Well that my friends is platform as a service platform as a service will usually be some infrastructure 01:34.520 --> 01:37.880 as a service aspect to it but that doesn't mean anything to me as a programmer. 01:38.030 --> 01:44.660 I don't care about what the internal LAN IP addresses for a server I don't even care if I have the servers 01:44.660 --> 01:49.880 or how many or what kind of RAM they have I don't care what kind of operating systems running on my 01:49.880 --> 01:50.680 machines. 01:50.810 --> 01:55.820 I don't really care what's on the firewall that that's all another world and I don't want to deal with 01:55.820 --> 01:56.830 all that. 01:56.900 --> 02:02.960 And that's what platform as a service is all about a cozy little cuddly world where developers can create 02:03.020 --> 02:04.860 amazing web applications. 02:05.090 --> 02:05.390 OK. 02:05.390 --> 02:06.620 More than web applications. 02:06.620 --> 02:08.820 But that's the best way to think about this stuff. 02:08.960 --> 02:13.130 And they can make these Web applications and press a button that all goes and everything's taken care 02:13.130 --> 02:19.100 of for them and they all live happily ever after to appreciate the platform as a service. 02:19.130 --> 02:20.120 I need to show you it. 02:20.240 --> 02:22.490 Let's take a look at one of the more popular ones. 02:22.550 --> 02:24.770 Heroku All right. 02:24.770 --> 02:27.170 Now this is the Heroku dashboard. 02:27.170 --> 02:29.380 It's a little bit boring to look at right now. 02:29.600 --> 02:32.870 Right now I have one application that's up there I don't want to mess with it. 02:32.870 --> 02:34.620 That one's actually working for a living. 02:34.700 --> 02:39.580 But what I do have is here on my computer here I've got this application. 02:39.580 --> 02:45.160 Now this is a little teeny tiny javascript application and the only thing it does is puts the word hello 02:45.160 --> 02:46.690 world up on the screen. 02:46.840 --> 02:51.310 But this could be a complete application this could be read it for example. 02:51.310 --> 02:58.990 So if you're familiar with the Reddit website so I can do any kind of code that I want and what I'm 02:58.990 --> 03:01.630 going to do in one shot is using Heroku. 03:01.810 --> 03:06.390 I'm going to take my code I'm going to upload it to Heroku. 03:06.460 --> 03:10.690 It's going to get everything configured is going to bring along libraries is going to check my code 03:10.690 --> 03:13.500 it's going to start anything that needs to be started. 03:13.750 --> 03:19.090 And it's actually going to give it a real U R L so it can post up and we can check it out and we can 03:19.090 --> 03:22.290 deploy this thing pretty much in the press of one button. 03:22.480 --> 03:24.170 So let's go ahead and get started. 03:24.700 --> 03:29.230 OK so here's my code then there's nothing too terribly exciting about my code all it's going to do is 03:29.230 --> 03:30.320 say hello world. 03:30.520 --> 03:38.540 But just so you know we look and explore here you can see it's on my desktop under a folder called node 03:38.610 --> 03:46.690 dash J J.S. dash sample so you can see there's files and there's folders We need all this to run Java 03:46.990 --> 03:50.920 JavaScript So let me go in and close that and I'll minimize this guy. 03:51.280 --> 03:53.080 And what we're going to do is bring it up. 03:53.080 --> 04:00.520 So we're going to go ahead and we're going to create a new app and we call it Fred. 04:00.520 --> 04:05.050 Now what's interesting here Samadi are you ready used Fred. 04:05.050 --> 04:08.010 So I can go ahead and do it graphically. 04:08.020 --> 04:14.620 But what's really interesting about Heroku is that most of this stuff is actually done from a command 04:14.620 --> 04:15.430 prompt. 04:15.490 --> 04:21.130 So if you want to use Heroku Well you could bring it in from Dropbox or anything else but all the hip 04:21.130 --> 04:27.670 kids will actually install a Heroku tool kit which will add command line utilities to let them do all 04:27.670 --> 04:28.480 the work. 04:28.480 --> 04:36.760 So in order for me to make this happen I need to open up a command prompt and run a few commands. 04:36.830 --> 04:37.750 Right so here I am. 04:37.770 --> 04:40.920 And if you remember this is desktop and that's the folder name. 04:40.960 --> 04:41.550 So 04:45.410 --> 04:47.330 first thing I'm going to do is create 04:50.810 --> 04:51.550 the app 04:57.150 --> 04:57.770 OK. 04:57.880 --> 04:59.350 Now look really close. 04:59.350 --> 05:04.450 It has created the application which is really just basically made a container for it up on Heroku but 05:04.450 --> 05:08.500 it already tells me now what the hell's going to be for the site. 05:09.430 --> 05:14.740 And this other one is used for something called a get which we can use to load stuff up. 05:14.760 --> 05:16.380 And I'm actually going to use that now. 05:25.280 --> 05:26.010 No titles. 05:27.820 --> 05:29.900 So I'm going to use this get command. 05:30.010 --> 05:33.410 And this is actually going to send all my files up. 05:33.490 --> 05:34.870 It's going to send my files up. 05:34.870 --> 05:37.810 It's going to create the web site and get everything started. 05:52.290 --> 06:00.720 Okay now if I've done everything right I now have a couple of commands and actually set up a complete 06:00.760 --> 06:02.740 website that runs my code. 06:02.940 --> 06:08.760 So what I'm going to do now is of course Heroku has another command line that allow me to actually open 06:08.760 --> 06:11.220 up a browser and check out my new web app 06:20.660 --> 06:22.370 Tenna. 06:22.490 --> 06:23.080 There it is. 06:23.090 --> 06:24.100 Hello world. 06:24.170 --> 06:30.700 Notice first of all that I've got an actual u r l it's under Heroku app dot com so they can make all 06:30.710 --> 06:38.480 these that they want but I'm legitimately up on the Internet and I can test this out do whatever I need 06:38.480 --> 06:39.250 to do. 06:39.260 --> 06:44.840 There are people who use this as an ongoing basis as I bring in new versions that takes care of everything 06:44.840 --> 06:45.710 for me. 06:46.100 --> 06:49.730 And that's the power of what platform as a service does for me. 06:49.910 --> 06:53.300 I don't really care much about servers or anything like that. 06:53.310 --> 06:55.440 Now let's say the Web sites were a little slow. 06:55.460 --> 06:57.240 Oracle lets me take care of that too. 07:07.310 --> 07:07.790 OK. 07:07.990 --> 07:09.980 So here's the app that I created. 07:09.980 --> 07:11.510 Then you can click on this. 07:11.920 --> 07:18.670 So let's say I want to build up a sequel server because I need a sequel server in the old days I would 07:18.670 --> 07:23.130 have to actually get a sequel server installed get it up and running with Heroku. 07:23.130 --> 07:27.970 I can just put in these add ons and there are zillions of add ons for all kinds of stuff. 07:29.570 --> 07:37.310 And see and isn't. 07:37.420 --> 07:43.690 So I'm a big fan of post Grace so I can actually just click on this if I want to and I've load myself 07:43.750 --> 07:48.200 in a complete sequel server just by going click. 07:48.530 --> 07:52.350 But we don't need any add ons for the simple app. 07:52.650 --> 07:58.870 Now the other thing that's interesting here what they called Duyne knows C programmers don't care about. 07:58.890 --> 08:02.150 Do we have enough web servers to do whatever we're going to do. 08:02.310 --> 08:08.240 Well I'm sure they care but only so far as they make sure that their application is running well. 08:08.280 --> 08:13.050 So let's say I deploy this and I got it up and running and it seems sluggish. 08:13.200 --> 08:18.140 Well it's no big deal with Heroku all I need to do is add more Didos. 08:18.150 --> 08:23.990 Now they cost more money as you add more but I add more Dido's until my applications running well and 08:24.030 --> 08:25.610 it's pretty trivial stuff. 08:25.860 --> 08:33.210 The beauty of platform as a service is that everything is avise skated as a programmer. 08:33.270 --> 08:35.460 I don't even see the servers. 08:35.460 --> 08:41.220 I don't see anything that I don't want to see other than my beautiful code running beautifully in its 08:41.220 --> 08:42.400 own little you are el 08:48.910 --> 08:49.620 in 08:57.740 --> 08:58.590 in.
