CME sends its first Globex cloud migration directly to Aurora in late 2027

CME has changed the route for the first production migration of its livestock markets to the cloud. The contracts are now intended to move directly to the new Aurora Cloud Region in late 2027, eliminating the interim Dallas production move. The exchange announced the revised route on 12 October after initial CME Globex performance testing.[1]

The new sequence moves the final Aurora destination forward while delaying the first livestock cloud production date. June’s plan had Dallas production in Q4 2026 and the Chicago-area environment in the second half of 2028. The October route replaces those two production steps with a direct Aurora move in late 2027.[2][1]

Testing continues across the revised sequence

The Dallas sandbox opened on 15 June with selected CME and CBOT equity-futures markets, excluding E-mini S&P contracts. Those were test instruments; livestock was the planned first production migration. Dallas remains available for disaster-recovery testing, and CME targets customer testing at Aurora in mid-2027.[2][1]

For intermediaries, removing the temporary production stop can reduce repeated installation and cutover work while extending support for the current production environment. It also changes the timing of expenditure and certification. These are operational implications of the revised sequence; CME has not quantified an average customer saving.

Deployment choice is part of the commercial design

CME’s June technical guidance describes customers using familiar co-location arrangements, specialised cloud services or a combination of the two. It identifies bare-metal and virtual-machine options rather than requiring every participant to adopt the same application architecture. The May notices likewise directed developers towards changing technical requirements and preparation programmes.[3][4]

The relevant architecture is the complete route from the participant’s order-entry application to the matching engine and back, together with market-data delivery and failover. Colocation, cloud services and hybrid arrangements can use different network and recovery paths, so each deployment needs testing against the participant’s own requirements.

Performance testing now feeds customer acceptance

CME reports faster round-trip times in initial testing. It has not published numerical latency results, load profiles or tail-latency distributions in the announcement. The next useful evidence for customers is performance under their workload, alongside recovery and operational testing.[1]

An acceptance programme can assess typical response time, the distribution of slower responses under load and recovery after a disruption. That gives a participant a basis for choosing among the available deployment options and preparing its own cutover.

Aurora construction, mid-2027 customer testing and the market-specific production transition remain the delivery milestones. The revised plan gives livestock participants a single cloud destination and a clearer sequence for preparing access to it.[1]
