The 2021 Cloud Report runs over 1,000 microbenchmark tests to evaluate CPU, network, storage, and TPC-C performance.
We want to help others understand the performance and cost tradeoffs of each cloud and its machines.
What's inside the 2021 Cloud Report?
For three years running, AWS has provided the lowest network latencies of any of the major clouds.
New to the report were machines running Amazon's ARM-based Graviton2 processors, which excelled on multi-core CPU benchmarks.
Microsoft Azure surpassed both clouds in storage I/O performance
Azure's ultra disk machines were high performers overall and proved themselves worth the higher cost for many workloads.
GCP outperformed the other clouds on every throughput benchmark.
GCP nearly tripled the performance of AWS and Azure clouds on network throughput.
This project is open-source and you are welcome to run the benchmarks yourself. You may just end up saving costs, increasing performance, and learning something new. If you have any questions about the report, we encourage you to get in touch with us via our public Slack channel or learn more via our YouTube channel.
