eWeek has an article on how Python is being used in enterprise systems:

ITA Software is using the Python language to empower its airline reservation system.

Many computer language purists say that languages such as Java, C++ or C should be used for enterprise applications. However, ITA, a Cambridge, Mass., provider of airline IT software and services, is proving that dynamic languages such as Python can be rock-solid for enterprise work.

[...] Much of the code ITA employs is written in Python, despite skepticism by some that dynamic languages are not ready for prime time. However, people such as Guido van Rossum, the creator of Python, point to the successful use of the language at places such as Google and YouTube, which endure enterprise-scale traffic on a daily basis.

[...] Each server requires a unique set of data feeds, and all the data feeds must be monitored to ensure the data arrives when expected and gets loaded as required, all while ensuring that system performance is not impacted by these data management tasks. ITA uses Python to automate all these tasks to make its systems reliable, easy to maintain and easy to update as its customers' needs change, Kelley said.

Moreover, ITA uses a Python application to monitor its heterogeneous production environment that contains hundreds of servers.

[...] Moreover, when ITA hires new people, the company likes to hire those with Python experience "because we've had a lot of luck with Python people having a lot of core problem-solving and system-building ability," Kelley said.

He said it is pretty easy to find Java or C programmers who are good at line coding but not generally good at problem solving. "It's much more unusual for us to find people who can analyze a problem domain and then implement a solution where they cross a bunch of problem domains," Kelley said.
