Case Study: Simplex Inc. achieves millisecond response, 8× performance and lower costs with A10 Networks AX Series

AX Series Selected for Financial Trading Systems Requiring Millisecond Response Time and Stability

Simplex Inc., a Japanese IT firm that provides cloud-based front‑office trading systems for financial institutions, confronted capacity limits and falling SSL throughput after moving from 1024‑bit to 2048‑bit SSL. With market spikes demanding millisecond response times and an existing SSL licensing model tied to transactions per second, Simplex needed a high‑performance, stable load‑balancing platform that kept costs and operational overhead low.

They deployed A10 Networks’ AX Series (AX 2500), achieving about eightfold better performance at half the cost, native 2048‑bit SSL handling, and virtualization via Application Delivery Partitions with aFleX scripting for an easy cutover. The result was immediate performance and stability gains, simpler Web‑GUI monitoring, reduced operational load, more flexible maintenance, and a scalable platform ready for future services.
