So after another very long break, we're back with show #13. This time our guest is Krishnan Subramanian who writes for CloudAve and can be found on Twitter as @krishnan. 

In this show we discuss the topic of the LAMP Cloud, which Geva started off in a GigaOm post, Who Will Build the LAMP Cloud?, and James responded to with Does cloud computing need LAMP?. In an indirectly related post, Krish wrote about the Relevance of Open Source in a Cloud Based World, so we invited him to join us in a conversation about the LAMP cloud: Does it make sense? Who needs it? And what's the role of open source software in the world of cloud computing?

We also talk about the adoption of Platform-as-a-Service and other topics.

Some of the companies, products and technologies mentioned in this podcast include: Amazon, Zend, Google App Engine, PHPFog, Salesforce.com, Engine Yard, Heroku and Microsoft Azure.

Fitting for Tax Day in the U.S., in this podcast we interview Alex Barnett, Developer Relations Group Manager for the Intuit Partner Platform (IPP) and the Intuit Developer Network (IDN). Intuit, of course, is the maker of TurboTax among other popular financial software. Intuit is often overlooked in the context of cloud computing, but as we find out in this podcast with Alex, they have been quite busy. Among other things we discuss:

• Intuit's activity in the cloud, including Quickbase, Quickbooks Online and other popular software products that they have moved to a Software-as-a-Service model
