I dont believe this. Maybe it's no longer used for "core banking services" but companies the size of JPMorgan have subdivisions that are as big as small/medium

I dont believe this. Maybe it's no longer used for "core banking services" but companies the size of JPMorgan have subdivisions that are as big as small/medium sized companies. There must be a lot of software written in <whatever language> that is still used inside the company.

I never worked at JPMorgan but a lot of the investment banks went towards a single platform for everything. JPMorgan had Athena, Bank of America had Quartz, and they both use Python. Goldman Sachs had something similar whose name I forget (slang?) At least in 2011 when I last worked in the industry, this sort of infrastructure was replacing the ad-hoc data-munging scripts that people used. It was even slowly eroding some of the Excel-based workflows designed by less software-engineery teams. 10 years later, I'm guessing it's only doing more than it was back then.

  That's true. Several companies I know are pursuing such endeavors. It's often even battle between Java & .NET as they are trying to focus on a single stack.

    The comment you reply to happens to hit the nail on the head. Some perl was slipped deep into some platform in the 2000s. While client software could be python, java or C# (usage has evolved quite a bit over the decades), they ultimately called and depended upon a bunch of Perl on some servers.

  I work at JPMC. Athena is a huge platform, but not everything is on it (for example the team I work on isn't). I very much doubt there aren't small perl scripts and tools still hanging around somewhere. But probably no large customer facing is running on perl anymore.
