I work for a systems integration consultancy at a large bank. Our team has successfully maintained a customer rewards calculation and distribution app written in Perl and SQL for several years now, deploying frequent changes ontime while maintaining high quality levels. The client's Architectural Dalek Council has now become aware of the use of Perl and is requesting a presentation providing a business case that Perl is suitable for production applications.

I strongly suspect that the only case with any traction is going to be based on actual, verifiable, contactable references citing the use of Perl in similar applications in similar large corporate environments, where 'similar' can be understood quite broadly, as long as it is something the audience will recognize as such eg not bioperl, or perl for multiplayer games.

With some internet searching it is possible to form the opinion that Perl in fact is widely used in financial services, but with no concerted effort by any party to provide verifiable evidence, it does not help cases like mine.

python at least has something. I cannot find any equivalent for Perl.

Can any monk(s) out there actually put forward a contactable reference of the use of Perl for financial services for medium to large data integration applications? Is it not high time such a list of Perl in different environments is created? The O'Reilly list was great 10 years ago, but now looks more like evidence Perl has fallen into disuse.

In reply to Perl in large corporates - verifiable success stories? by properly
