HCL used MuleSoft's Anypoint Platform to build a digital foundation for a large $28 billion enterprise customer with over 1.9 million employees serving 68 million people daily across 119 countries. The solution involved standardizing business capabilities, implementing them as layers, and creating shared services for common functionalities. Microservices were developed using MuleSoft components like API Manager, Runtime Manager, and connectors to create a flexible, scalable, and secure architecture deployed across multiple countries. The outcome was over 471 million successful transactions on the platform with average and peak response times under 120ms and 500 transactions per second respectively, serving over 150 APIs.
