It's hard to talk about infrastructure as a service and platform as a service without mentioning software

00:07.290 --> 00:11.910
as a service software as a service really doesn't have much to do with virtualization but given its

00:11.910 --> 00:15.150
name I feel kind of obligated to talk to you about it right now.

00:15.150 --> 00:18.020
In fact software as a service predates virtualization.

00:18.030 --> 00:19.990
It's been around a while.

00:20.310 --> 00:27.030
The cornerstone about software as a service is that instead of having a CD that you buy at the store

00:27.610 --> 00:33.870
or whatever online and sticking it in your computer and installing the software you instead buy a subscription

00:34.110 --> 00:39.540
and then this subscription allows you to download x number of copies and do whatever you want to do

00:39.540 --> 00:40.340
with them.

00:40.350 --> 00:45.330
So software as a service gets rid of optical media and things like that first of all which is kind of

00:45.330 --> 00:50.790
handy now probably one of the more famous versions of software as a service and something I personally

00:50.790 --> 00:54.000
use is Microsoft's Office 365.

00:54.060 --> 00:59.190
When you write books for a living use a lot of Microsoft Word and I'm always moving and changing computers

00:59.190 --> 01:00.220
and things like that.

01:00.310 --> 01:03.310
And I can never keep track of all my optical media.

01:03.330 --> 01:09.930
So for me I just get a subscription I pay I think it's $99 a year and I can install Office on up to

01:09.930 --> 01:12.150
five computers and five tablets.

01:12.150 --> 01:13.710
So for me it's really convenient.

01:13.710 --> 01:19.530
In fact I can even share one of mine with a family member or something like that so that software as

01:19.530 --> 01:20.160
a service.

01:20.160 --> 01:26.730
Now I need to be careful here because the description I just gave you is what I'm thinking that Conti

01:26.760 --> 01:31.940
is going to use this software as a service but I'm going to challenge you with something to me there's

01:31.950 --> 01:34.900
a whole other way to look at software as a service.

01:35.070 --> 01:42.120
For example applications like oh I don't know Dropbox with Dropbox I can store stuff online.

01:42.150 --> 01:43.110
It is a subscription.

01:43.110 --> 01:44.940
I have to subscribe to Dropbox.

01:44.940 --> 01:51.150
They don't just let anybody on there but it has good controls and I can access my stuff anywhere so

01:51.330 --> 01:57.480
it doesn't really download software on my computer but it provides an application a service that I can

01:57.480 --> 01:58.530
use anywhere.

01:58.530 --> 02:07.650
So to me things like Dropbox GS Google Docs Google Maps all of these tools are in my opinion also examples

02:07.680 --> 02:09.570
of software as a service.

02:09.570 --> 02:14.910
So I can't really guarantee which way the company is going to be looking at things but make sure you

02:14.910 --> 02:18.390
understand both ways I've just described software as a service.
