To address the challenge of running Redis with persistence storage on AWS, a recent study was conducted to assess the impact of persistent storage on performance. The study found that, despite concerns about slow EBS and AOF being more demanding than snapshotting, running Redis with persistence storage using AOF with "fsync every second" policy does not significantly affect Redis' performance under normal conditions. In fact, the average response time was only 1-8% higher with data-persistence on most platforms, and the difference was negligible when using a non-raided EBS configuration. The study also found that the optimal EBS configuration of the Redis Cloud platform results in better performance, especially for smaller instances where shared servers can lead to significant latency gaps. Overall, the study suggests that AOF with "fsync every second" policy should be considered as the default Redis configuration for users running on AWS, and the Redis Cloud's architecture provides a unique advantage in terms of performance and cost-effectiveness.
