Performance and Resilience in Next‑gen Trading Tech

In Conversation with Steve Grob: Deepak Dhayatker and Paul Weiss

Join Steve Grob, founder of Vision 57, as he chats with CTO leaders Deepak Dhayatker, from Rapid Addition, and Paul Weiss, from Adaptive. The group talks about how Aeron enables microsecond latency, strong consistency, and always-on resilience. They go on to cover buy-and-build strategies, cloud readiness, and what’s next for enterprise-scale trading.

Learn how Aeron has helped Rapid Addition achieve performance and consistency:

• How has Aeron evolved and what changed post-acquisition by Adaptive?
• Where does Aeron fit in Rapid Addition’s stack?
• What new Aeron capabilities are most relevant to CTOs?
• How does Aeron address the performance vs. resilience trade-off?
• What design principles help achieve deterministic low latency?
• How does buy-and-build accelerate delivery and reduce risk?
• Where is Aeron heading next?

How has Aeron evolved—and what changed post-acquisition by Adaptive?

Aeron’s open-source foundation catalyzed a robust community and a new standard for capital markets messaging. With Real Logic’s team now part of Adaptive, Aeron’s tech sits under one roof with delivery and proprietary IP, enabling full-stack, front-to-back solutions that combine superior performance with enterprise resilience.

Where does Aeron fit in Rapid Addition’s stack—and why?

Rapid Addition uses Aeron Transport for inter-service messaging, front-to-back communication, and command-response patterns, as well as Aeron Archive for replay, recovery, and slow-consumer handling. The result: deterministic behavior, zero/low GC, and predictable performance at scale.

What new Aeron capabilities are most relevant to CTOs?

According to our panelists, high interest areas include Aeron Cluster, kernel bypass, cloud benchmarking across major cloud providers, and secure streams. These capabilities reduce code complexity, cut total cost of ownership, and harden reliability for cloud or hybrid deployments.

How does Aeron address the performance vs. resilience trade-off?

Aeron’s technology suite (Transport, Archive, Cluster) is built for capital markets’ microsecond SLAs and strong consistency. It applies replicated-state-machine principles and lock-free constructs to deliver low latency, fault tolerance, availability, and reliability in a single, coherent stack.

What design principles help achieve deterministic low latency?

Our panelists suggest to keep systems simple and deterministic: remove nondeterminism (GC, jitter), pin/isolate threads, manage busy-wait cycles, and use single-threaded/lock-free models (e.g., Disruptor). Replicate critical state via low-latency transport for fast failover, and build observability into your platform from day one.

How does buy-and-build accelerate delivery and reduce risk?

Writing low-level infrastructure is costly and brittle. Adopting best-of-breed technology (such as Aeron for transport/cluster/archive; FIX engines from the likes of Rapid Addition), lets firms focus on differentiated IP—matching, risk, pricing—while ensuring resilience is baked in, not bolted on.

Where is Aeron heading next?

Aeron is doubling down on enterprise-scale state management using replicated state machines. Moverover, them team is working on continued optimization, cloud performance benchmarks, and secure streaming.
