In December 2019, we published the 2020 Cloud Report and an accompanying blog post, which summarized original research we conducted benchmarking the performance of Amazon Web Services (AWS), Microsoft Azure (Azure), and the Google Cloud Platform (GCP).

Since 2017, Cockroach Labs has run thousands of benchmark tests across dozens of machine types with the goal of better understanding performance across cloud providers. If there’s one thing we’ve learned in our experiments, it’s this: benchmarking the clouds is a continuous process. Since results fluctuate as the clouds adopt new hardware, it’s important to regularly re-evaluate your configuration (and cloud vendor).
