For de-centralized organizations, multiple cloud instances and databases can drive up costs, limit scalability and maintainability, and prevent growth. In this session, you’ll learn how to enable and accelerate multi-tenancy for optimal performance and efficiency. You’ll hear lessons and best practices from Capgemini’s work implementing multi-tenancy at the infrastructure, platform, and application levels while ensuring seamless operation across any cloud environment thanks to Red Hat OpenShift. There will also be a discussion of how accelerators like Capgemini’s Digital Cloud Platform can cut time to market by up to 50%.
