There was a time when Java and C# were all an enterprise developer really needed to know in terms of programming languages. Today, that's no longer the case.
Language proliferation and integration is becoming a key development challenge as enterprises find themselves adopting a variety of languages for mission-critical applications.
To Tim Bray, director of Web technologies at Sun and the co-author of XML (define), not only is an era of language proliferation upon us, the sole way an enterprise can cope is to be open.
Bray argued that in the last few years, Ruby on Rails, Python, PHP and other development languages are now being used for mission-critical enterprise applications. The days when the CIO could say they're a Java or .NET shop just aren't here anymore, he said.
For Sun, the need to understand language diversity isn't just a curiosity -- it's also good business strategy.
"We sell stuff at Sun and if developers want to build in Rails, then we want to be their friends -- so when it comes time to deploy, they'll deploy on Sun," Bray said.
"XML doesn't have the monopoly it used to have," Bray said. "It used to be that if you wanted to send messages back and forth across the wire, XML was the only game in town."
"Clearly, there is going to more heterogeneity for wire formats, too," he added. "Increasingly, given that the future will have more than two programming languages, there will be a lot more messages being passed around."
