Highlights include Graviton powering up to 49% of EC2 compute, EBS peaking at 24.8 trillion I/O operations, Lambda handling 2.3 trillion invocations per day, DynamoDB processing 59 trillion requests with peaks of 192 million requests per second, ElastiCache serving 2.3 quadrillion daily requests, and GuardDuty monitoring 14.08 trillion log events per hour. The post closes with a promotion for AWS Countdown Premium, a service for managing infrastructure during business-critical traffic spikes. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How many requests per second did DynamoDB handle during a major Amazon sales event? DynamoDB peaked at 192 million requests per second during Prime Day 2026, while maintaining single-digit millisecond response times and high availability. Across the four-day event from June 23 to June 26, it processed over 59 trillion requests total, powering Amazon properties including Alexa, Amazon.com, and fulfillment centers. _Engineers benchmarking database throughput at scale can follow real-world DynamoDB numbers like these on daily.dev._ ### What percentage of Amazon's EC2 compute runs on AWS Graviton processors? AWS Graviton powered up to 49% of the Amazon EC2 compute used by Amazon.com during Prime Day 2026. This reflects a significant and growing share of Amazon's own workloads running on Arm-based Graviton instances rather than traditional x86 EC2 instances. _Teams weighing Graviton adoption for cost and performance can track real production adoption figures via daily.dev._ ### How many AWS Fault Injection Service experiments does Amazon run to prepare for Prime Day traffic? Amazon ran over 44,000 AWS Fault Injection Service experiments ahead of Prime Day 2026, more than six times the number conducted in 2025. These chaos-engineering style experiments help ensure Amazon.com remains highly available during the high-traffic event. _Developers building resilience testing practices can follow chaos engineering benchmarks like these on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@ahmetozel** · 0 upvotes > The 44,000 fault-injection experiments are more informative to me than the peak request counts, but the experiment count alone does not show which failure combinations were covered. A service can recover from an isolated fault at normal load and behave differently during a sales burst when its fallback dependencies are already busy. > > I would connect each experiment to a customer-facing outcome and include the recovery interval, not just whether the service stayed available.
