Carrier Case Study

Just one year into its three-year migration and modernization plan, Carrier experienced substantial benefits. The adoption of AWS fostered innovation, enhanced resiliency, and increased agility. By setting high architectural benchmarks and designing customized, automated solutions on AWS, Carrier successfully migrated and remediated approximately 1,300 servers. The elasticity of AWS allowed for the retirement of over 400 servers' worth of workloads, resulting in millions of dollars in direct cost savings. This modernization effort also spurred product development and innovation across the team.

Carrier utilized Amazon AppStream 2.0 to replace server farms, ensuring critical workloads like payroll processes run on a fully managed, up-to-date service where AWS handles infrastructure maintenance. This allowed Carrier's team to focus on building solutions and standardizing architectural patterns. Furthermore, the implementation of Amazon Aurora and Amazon Relational Database Service (Amazon RDS) enabled a self-service development model. Engineers can now provision infrastructure in 30 minutes, a drastic reduction from the previous 35 days, significantly boosting employee morale and productivity. The company has seen a 45–50 percent reduction in infrastructure costs and a 20 percent reduction in total infrastructure.

Security benefits were also realized through this digital transformation. The economy of scale provided by AWS, with its constant monitoring against cyber threats, combined with the inherent security advantages of newer, modernized technologies, has strengthened Carrier's security posture. Looking ahead, Carrier plans to apply machine learning algorithms to data collected from its devices for real-time forecasting, pattern analysis, and proactive problem resolution, further enhancing customer satisfaction and product development. The ongoing migration and modernization efforts on AWS are positioning Carrier for continued innovation and high availability.
