In capital markets, operational success is built on predictable performance and low latency, where even tiny variations in packet timing alter queue priority and trade execution. At the same time, both exchange venues and their participants face mounting constraints in traditional on-premises data centers — from power and physical rack space limits to lengthy hardware procurement cycles. Increasingly, global capital markets seek the speed and determinism of physical co-location combined with the dynamic scalability and automation of the cloud.
At Google Cloud Next ‘26, we announced the Ultra Low Latency (ULL) Solution , now generally available, providing high-frequency trading workflows that run in the cloud with an ultra-low latency network and agility. The ULL Solution includes the new U4 machine family , also generally available today.
The ULL Solution is based on three infrastructure pillars: Hardware-level networking: Scaleable, hardware-based multicast data distribution for reliable market-data feeds Advanced networking observability: Dynamic network traffic capture with hardware-level timing accuracy, facilitating consistent auditing, market replays, and absolute trade validation without impacting primary traffic performance Deterministic high-performance compute: Processing of latency-critical execution tiers in a highly predictable, consistent amount of time, every single time Taken together, the ULL Solution’s compute, storage, networking, and observability provide financial exchanges and market participants with a number of technical capabilities: Bare metal performance: Dedicated bare metal compute provides direct access to physical host resources, minimizing jitter and delivering predictable, low-latency execution for market-data feeds and order routing.
High-performance storage options: Local Titanium SSDs handle real-time transaction and tick logging on the host, complemented by scalable Google Cloud Hyperdisk for persistent market data archives and analytics. Physical traffic isolation : The ULL trading fabric’s redundant A/B multicast market feeds are accessed through two independent and dedicated Titanium adapters , while an independent third Titanium adapter offloads telemetry, management, and provides access to Google Cloud services. Hardware-accelerated multicast distribution: The ULL network architecture supports hardware-level multicas
