For a bank, Lambda is brand new.

You haven’t worked in conservative industries I take it? Late adopters, every one.

OP is still trying to replace Cobol. I know an insurance company that started that process 15 years ago. Fifteen years.

Do you mean figuratively that OP is replacing Cobol? Because I don't see that in the article. It mentions other technology that I would not associate with a super-conservative stack - like Databricks, JSON, Postgres and Google Analytics. So I'm a bit confused by your comment. And by all the downvotes, honestly.

I just pointed out that personally I would not consider Lambda - which has been a stable and popular technology for 10 years - to be cutting-edge. It's not old but also not cutting-edge imo. I would reserve that term to newer technology. Apparently a controversial view on HN, which is interesting.

To respond to your question, I did work for a bank in 2017 with moving certain burst-type processing to a set of Lambdas.
