What is Lloyds Banking Group's technology stack?
Lloyds Banking Group runs a multicloud estate that it has rebuilt since 2021. Its July 2026 half-year presentation says more than 60% of applications are on cloud, against a negligible share in 2021, that data centers have been cut by more than 50% and that legacy applications are down c.25%, with a c.35% gross reduction in run and change technology costs. The named building blocks are Google Cloud's Vertex AI for machine learning, used by over 300 data scientists and AI developers after 15 modelling systems were migrated from on-premise infrastructure; Oracle Database@Azure for the Oracle databases behind its banking services, under a multi-year agreement of March 2025; Envoy, an agent platform built with Google Cloud; and Microsoft 365 E7 with GitHub Copilot for over 10,000 engineers. Chief operating officer Ron van Kemenade told investors in November 2025 that Lloyds had hired over 8,000 engineers over four years. The Accelerate 2030 plan extends a new core banking engine across products; Lloyds does not name its vendor.[1][2][3][4][5][6]

Which cloud providers does Lloyds Banking Group use?
Google Cloud and Microsoft Azure are both named in primary sources. Lloyds' machine-learning platform and its Envoy agent platform are built with Google Cloud, and Oracle said in March 2025 that Lloyds is moving its Oracle databases to Oracle Database@Azure, which runs inside Microsoft Azure data centers. Lloyds has not published the split.
How much of Lloyds' technology is in the cloud?
More than 60% of applications, according to the half-year results presentation of July 30, 2026, which describes the 2021 share as negligible. The same slide reports a reduction of more than 50% in data centers and legacy applications down c.25% since 2021.
How many engineers does Lloyds Banking Group have?
Lloyds reports hires rather than a total. Its chief operating officer said in November 2025 that it had hired over 8,000 engineers over four years, and the July 2026 results presentation counts c.11k tech and data hires since 2021. GitHub Copilot has been deployed to over 10,000 of its engineers.
What is Lloyds' Envoy platform built on?
Envoy was built with Google Cloud, Lloyds said when it unveiled the platform in 2026. It gives teams templates for building AI agents, built-in safety and risk checks, monitoring with a complete audit trail and an internal Agent Marketplace, and it connects to the group's existing Large Language Model platform.
Which core banking system does Lloyds use?
Lloyds does not name one. Its Accelerate 2030 plan, presented on July 30, 2026, says it will extend a new core banking engine across products to increase speed to market and personalisation, without identifying the vendor or how many products already run on it.
