Cloud Migration Saves Money for Health Insurer

The Challenge

A major health insurer was experiencing sharp swings in demand for its key client-facing applications, with 80 percent of the load occurring during open enrollment periods. Maintaining the applications internally also inflated the company’s operational costs. The insurer approached Cognizant to manage application performance as well as reduce IT infrastructure costs to ensure high performance at reduced cost while efficiently serving employees, customers and providers. The goal was to move client-facing applications from the company’s legacy platform to a more economical and efficient one, managing every step involved in the process.

Our Approach

To curb operational costs and efficiently manage the applications, Cognizant partnered with Pivotal, a comprehensive and open-source cloud-native platform, and educated the insurer’s staff about Pivotal’s capabilities. We also performed the analysis, design and remediation, integration, validation, release of applications to the Pivotal Cloud Foundry (PCF) platform, and program planning and management. 

Within a span of five months, Cognizant's Digital Engineering team migrated 18 critical applications from the company’s legacy infrastructure to the PCF platform, reducing application failures and helping the insurer move to a DevOps development model. This accelerated the process of moving applications into production, helped the insurer move from monthly to weekly code releases and eliminated the need for downtime due to upgrades or refreshes. Using the New Relic performance monitoring and management tool helped uncover patterns and resolve issues at a transaction level.

Cloud Migration Improves Application Performance, Reduces Cost

Adopting agile and lean development methodologies, dynamically reallocating resources among applications in the shared PCF environment and using technologies such as autoscaling not only dramatically improves application performance but also reduces infrastructure costs. Simplified infrastructure management increases the productivity of developers.
