Insurer Marsh McLennan Selects AWS as Preferred Cloud Provider

May 16, 2025 | Posted by Abdul-Rahman Oladimeji

Insurance giant Marsh McLennan has selected AWS as its preferred cloud provider across its four global businesses - Marsh, Guy Carpenter, Mercer, and Oliver Wyman. The company will migrate the majority of its global on-premises infrastructure to AWS, significantly reducing the company's physical data center footprint. Some workloads will remain on-premises to meet the company's data management obligations.

"Our clients are facing increasingly complex challenges that require agile, data-driven responses," said Paul Beswick, Marsh McLennan's chief information and operations officer. "With AWS and its deep experience in large-scale migrations and leading cloud capabilities, we will significantly enhance our ability to provide our clients with the power of our perspective through faster insights and more innovative solutions at the speed they need and expect."


"Working with AWS, Marsh McLennan will enable deeper client insights while meeting the regulatory requirements of the financial and professional services sectors. At the same time, they will be able to scale their AI innovations and accelerate time-to-market for new services."
