Open source is coming to financial services
As someone who develops software products for the financial services sector, I can assure you that the thing most stakeholders are looking for right now is simplification of operations, not sharding operations out to even more vendors (OSS or otherwise).Every single one of our customers is looking for a path back to something that looks like the mainframe in terms of vertical integration of the business stack. Most got taken for a really bad ride by legions of consultants over the last ~2 decades and now have to visit 5-10 different system interfaces to take care of a single customer -  A horrible combination of green screen, web sites and random pieces of paper that have to be scanned in just right. The list of procedures for some types of activities is bigger than the stack of disclosures the end customer receives.Many of our clients are stuck in some contorted stance with half their stack in AS400-land and the other half scattered to the various "cloud" services which are mostly just random websites/services with shitty SOAP APIs (or no APIs at all).The only financial services companies that are seeing positive uplift from these sorts of initiatives are those with enough resources to try this path, fail at it, and then decide they wanted to build 100% of their own stack in-house anyways.
