WarpStream S3 Express One Zone Benchmark and Total Cost of Ownership

WarpStream, a pioneering data streaming system built on object storage without local disks, offers significant cost efficiencies compared to Apache Kafka, albeit with added latency. Initially, WarpStream's support for S3 Express One Zone (S3EOZ) reduced latency but also increased costs due to S3EOZ's pricing. Recent AWS price cuts for S3EOZ have made it more competitive, prompting WarpStream to revisit its benchmarks and total cost of ownership analysis. Results show WarpStream achieving significantly lower latency than other zero-disk systems, with a P99 Produce latency of 169ms. The system is cost-effective, with infrastructure costs totaling $2,961 per month, which is substantially cheaper than equivalent Kafka setups. WarpStream offers better durability and reliability, operating across multiple availability zones at no extra cost and auto-scaling to prevent disk space issues. Users can further reduce costs by opting for S3 standard, and detailed pricing comparisons are available via WarpStream's public pricing calculator.
