AWS cares about your bill... in a good way!
Let me tell you a story about my recent findings. While building an IoT solution for one of my customers, I realized that the Lambda service was not accessible in the customer’s AWS Account. Since I know how to manage permissions, I decided to add the required privileges to my AWS user. To my surprise, the AWS console still presented the Access denied with UnknownError.
That was a bit strange, so I granted myself Administrator privileges to investigate the issue.
