Amazon Web Services (AWS) previewed a new service at the recent AWS re:Invent 2019 conference that uses machine learning (ML) to automate Java code review. Unveiled during the keynote by AWS CEO Andy Jassy, the new CodeGuru service uses models and algorithms built on millions of code reviews Amazon has done in-house over the last 20 years.

"The question that dominates our conversations as we're thinking about what to work on and spend resources on next," Jassy told his audience, "is what else can we build that can give value to you in places where we’ve done this over a long period of time at Amazon? One of the areas ... that we thought we might be able to help further ... is code review."
