Jan 14, 2021 By Kay Plößer In Dashbird

One problem that pops up quite frequently when people try to build serverless applications with AWS API Gateway and AWS Lambda is Execution failed due to configuration error: Malformed Lambda proxy response. There is nothing worse than generic error messages that don’t tell you anything you need to fix the problem, right? And AWS isn’t particularly known for its error message design, if you can even call it that, let alone for giving you the means of fixing the problem.

Lightrun & JFrog - Achieving Complete Agility With Continuous Debugging And Continuous Observability

Nov 19, 2020 By JFrog In JFrog
CI/CD has become the de facto standard for infusing the software development process with hardcoded agility. Organizations are now integrating DevOps concepts and practices into their workflows in order to get great features out of the door faster and reduce internal friction. But your ability to understand what’s going on in a production service is pre-defined by the logs, metrics and traces (i.e. the three pillars of observability) your developers pre-defined during development. There is, however, a need for agility even after the service is live - in order to adhere to strict SLAs, decrease MTTR and save on logging costs.
