To address this challenge, Ulta Beauty has implemented Google Kubernetes Engine (GKE) and MongoDB Atlas, enabling the development of cloud-native applications that provide better customer experiences. The company's system overhaul has allowed them to launch new products and services faster, create dynamic and personal connections with customers, and handle increased traffic during the holiday season with ease.
