I procured my Aurora intel from a lengthy phone conversation with an exceptionally knowledgeable (and excessively talkative) AWS engineer – who had worked on Aurora – several years ago. The engineer provided detailed explanations of Aurora’s architecture, do's, and dont's as part of our engagement with AWS. The engineer was very proud of AWS’ accomplishments (and I concur that their «something serverless» products are remarkable engineering feats as well as significant cost-saving solutions for me and my clients). The engineer was willing to share many non-sensitive technical details. Generally speaking, a sound understanding of distributed architectures and networks should be sufficient to grasp Aurora Serverless. The actual secret sauce lies in the fine-tuning and optimisations.
