F<strong>in</strong>ally, it reduces the price po<strong>in</strong>t of cloud comput<strong>in</strong>g, <strong>and</strong> consider<strong>in</strong>g the previous<br />
two po<strong>in</strong>ts, cost is the core sell<strong>in</strong>g po<strong>in</strong>t of the clouds.<br />
<strong>Cloud</strong> providers see the value of promot<strong>in</strong>g <strong>in</strong>teroperability even though<br />
many would love to have the customer locked <strong>in</strong>. However, <strong>in</strong> these days when<br />
open source is a much better sell than proprietary features, cloud vendors<br />
could f<strong>in</strong>d that provid<strong>in</strong>g <strong>in</strong>teroperability gets many enterprises off the fence<br />
<strong>and</strong> mov<strong>in</strong>g toward the clouds.<br />
The success of <strong>in</strong>teroperability with<strong>in</strong> the cloud providers’ realms will<br />
depend on their ability to stop build<strong>in</strong>g features <strong>and</strong> start build<strong>in</strong>g for <strong>in</strong>teroperability.<br />
With the huge l<strong>and</strong> grab go<strong>in</strong>g on right now, that is easy to talk about<br />
but tougher to do. At the end of the day, cloud users will have to <strong>in</strong>sist on<br />
openness, as they did <strong>in</strong> the world of <strong>SOA</strong> <strong>and</strong> other architectural shifts <strong>in</strong><br />
th<strong>in</strong>k<strong>in</strong>g.<br />
This could very well be one of those times when everyone talks a good<br />
game <strong>and</strong> pays dues <strong>in</strong>to some organization promot<strong>in</strong>g st<strong>and</strong>ards, but the<br />
solution cont<strong>in</strong>ues to be proprietary because of the cost <strong>and</strong> latency that the<br />
cloud providers will have to suffer when coord<strong>in</strong>at<strong>in</strong>g with their competition.<br />
Aga<strong>in</strong>, end users will have to make it a core criteria for provider selection. As<br />
with anyth<strong>in</strong>g, money talks.<br />
Platform-as-a-Service<br />
Platform-as-a-service is a complete platform, <strong>in</strong>clud<strong>in</strong>g application development,<br />
<strong>in</strong>terface development, database development, storage, <strong>and</strong> test<strong>in</strong>g,<br />
delivered through a remotely hosted platform to subscribers. Based on the<br />
traditional time-shar<strong>in</strong>g model, modern platform-as-a-service providers offer<br />
the ability to create enterprise-class applications for use locally or on dem<strong>and</strong><br />
for a small subscription price or for free.<br />
You can th<strong>in</strong>k of platform-as-a-service as one-stop shopp<strong>in</strong>g for those<br />
look<strong>in</strong>g to build <strong>and</strong> deploy applications. Platform-as-a-service provides<br />
self-conta<strong>in</strong>ed platforms with everyth<strong>in</strong>g you need for application development<br />
<strong>and</strong> operational host<strong>in</strong>g. Platforms such as Google App Eng<strong>in</strong>e <strong>and</strong><br />
Force.com (part of Salesforce.com) are popular ways to approach application<br />
development on the cloud.
