Summary

Amazon's introduction of the Arm-based Graviton processors in their EC2 service has presented a competitive alternative to the traditional x86 architecture for data-intensive applications, like those using Redpanda. Launched in 2018, the initial Graviton chips offered a promising price-to-performance ratio, but it was the release of Graviton 2 in 2020 that marked a significant leap in performance with up to 64 cores and 512 GiB of RAM. These Arm-based instances demonstrated a 20% edge in price/performance compared to Intel instances for high-throughput tasks, such as message ingestion in Redpanda, while also offering smoother regulation of SSD throughput. Benchmarks showed that Graviton 2 instances maintain consistent performance without the throughput oscillation observed in some Intel instances, making them a viable option for storage-intensive workloads. Furthermore, the process of porting applications to Arm, while potentially challenging for compiled languages, proved manageable for Redpanda, which benefited from thorough build process adjustments. Overall, Amazon's Graviton 2 instances provide a strong consideration for organizations seeking cost-effective and efficient cloud computing solutions.
