Dealing with Dark Debt: Lessons Learnt at Goldman Sachs

Thursday, 30 August, 2018 - 09:0009:55

Vanessa Yiu, Goldman Sachs International


Dark debt is a form of technical debt that is invisible until it causes failures. In enterprise systems, technical engineering liabilities often develop over time due to system complexities, and changes down the line might have unintended consequences due to unforeseen inter-dependencies or hidden problems.

In this talk, we will cover strategies to prevent and mitigate dark debt, as well as tools we have developed or adopted at Goldman Sachs to help manage complexity across our environment.

Attendees of this session can expect to learn:

  • Challenges of managing distributed systems
  • Practical tips on how to manage technical debt in your environment
  • How SRE can help with tackling this form of risk
