Question

I think this mostly applies to web applications, since you often see things like language and database vendor in regards to web applications, but not so much on desktop applications.

If a web application is created using language X, would that have any noticeable impact on who deploys the application? For example, would a company that uses .NET products ever consider using a Python application that meets their needs or would they tend to find a .NET product that they could use?

EDIT 1: Refined the question to refer to apps meant to be deployed, not just used.

Answer 1

I assume that you are talking about companies purchasing and deploying web applications within their organizations. If you are talking about just using external applications, I don’t think they notice or care.

I think this is very subjective, but from my past experience, companies tend to go with the technologies they already have installed and running. They tend to do this for several reasons.

• The new application will require fewer changes to existing infrastructure (for example, getting PHP running on IIS)
• Interop with existing applications is probably going to be easier
• They probably already have expertise in-house to support whatever language/server/db, etc that they are currently running.
• Their IT people may have already formed prejudices towards the other languages/OS/db

Every time I have gone out to evaluate web applications in the past, I have limited my search to the technologies we were already using.
