London Stock Exchange Group has announced a collaboration with Amazon Web Services aimed at modernising the infrastructure underpinning its real-time market data services, as part of a broader cloud transformation strategy.
Under the collaboration, LSEG will leverage AWS services to support the collection, routing, and distribution of its Full Tick and Real-Time Optimized data, while continuing to operate the services within its own private cloud environment. The objective is to improve flexibility, speed, and resilience in the delivery of real-time financial data to market participants.LSEG’s real-time data services sit at the core of its Data & Analytics business. The group distributes market data from more than 575 exchanges and trading venues worldwide, covering over 100 million instruments and delivering hundreds of billions of data updates each day.
Matt Eddy, Global Head of Real Time, Quant & Economic Data Solutions, tells TradingTech Insight how this collaboration fits into LSEG’s broader cloud and data platform roadmap: “This transformation of our real-time data infrastructure is part of our multi-cloud approach and follows a robust RFP process to determine the most suitable partner to go on this journey with. There is no impact to our existing cloud partnerships as part of this programme.”
From a technology perspective, the collaboration highlights LSEG’s decision to combine hyperscaler capabilities with a controlled private-cloud architecture, rather than adopting a purely public-cloud distribution model. This approach is intended to preserve operational control and resilience while enabling elastic scaling and improved handling of peak data loads, and is differentiated from pure public-cloud distribution models used elsewhere in the market, notes Eddy.
“LSEG has long-standing engineering relationships with the major cloud vendors and operates a multi-cloud strategy,” he explains. “These relationships have yielded significant improvements for low latency high performance workloads. For this programme, we do not yet consider that public cloud is mature enough to support the rigorous needs of our LSEG Real-Time platform. This platform will run in LSEG’s private cloud, ensuring we can benefit from the flexibility and resilience of a cloud platform, with the added performance and security of this being in a private cloud environment.”
While the announcement does not introduce new client-facing products, it signals a significant investment in the underlying infrastructure that supports LSEG’s real-time data services. As market participants increasingly architect trading, risk, and analytics workflows around high-frequency, event-driven data, the scalability and reliability of market data distribution infrastructure is becoming a differentiator rather than a background concern.
The collaboration also reinforces LSEG’s positioning as a global market infrastructure provider focused on long-term platform resilience and data accessibility, as firms across the buy side and sell side continue to adapt their data strategies to cloud-native and AI-enabled operating models.
“As customer demand for data continues to grow in line with ever increasing market data volumes, a key outcome for this programme will be the increased scale, flexibility and agility that LSEG Real-Time will be able to support,” says Eddy.
Tanuja Randery, Managing Director, AWS EMEA, commented: “Our collaboration with LSEG will help financial institutions navigate the exponential growth in market data, which now peaks at up to 20 million messages per second on LSEG’s real-time network. By combining AWS’s scale, resiliency, and flexibility with LSEG’s position in real-time data distribution, we are enabling financial institutions to process billions of data points with the speed and intelligence that modern financial markets demand.”
