The 2022 Cloud Report by Charlie Custer provides insights into the performance of AWS, GCP, and Azure for OLTP applications, revealing several key findings. The report suggests that latency differences among the three major cloud providers are negligible, making it a non-critical factor in choosing a provider. It also indicates that high-performance storage options typically do not justify their cost except in specific high-demand scenarios, as their price can significantly increase overall operating expenses. Smaller instance types, particularly those with 8 vCPUs, are found to offer better price-for-performance compared to larger instances, with AMD Milan processors showing notable efficiency. Additionally, some GCP and Azure instances occasionally deliver more throughput than advertised, although these are not consistent enough to be relied upon for high-performance needs. The full report, available for free, provides a comprehensive analysis of over 50 instance types across the three cloud platforms.
