GCP Outpaces Azure, AWS in the 2021 Cloud Report

The 2021 Cloud Report by Cockroach Labs has found that Google Cloud Platform (GCP) outperforms Amazon Web Services (AWS) and Microsoft Azure in terms of throughput, CPU performance, network latency, and storage I/O. GCP delivered the most throughput on all four benchmarks: network throughput, storage I/O read throughput, storage I/O write throughput, and maximum tpm throughput. In terms of CPU performance, AWS's custom-built Graviton2 Processor outperformed Intel and AMD processors in the 16-core benchmark. AWS also had unbeatable network latencies for three years running. Azure's ultra disks were found to be worth the expense, while GCP's general purpose disk matched performance of advanced disk offerings from AWS and Azure. The report suggests that more nodes, memory, and better CPUs are better investments than advanced disks for improving OLTP performance.
