Refer to the Dress4Win case study. Dress4Win is a web-based company that helps users organize and manage their personal wardrobe using a web app and mobile application. They also have an active social network connecting users with designers and retailers. The company hosts its infrastructure in a single colocated data center but is now committing to a full migration to a public cloud due to rapid growth. Their infrastructure includes several hundred servers and appliances running Ubuntu LTS v16.04. The setup consists of MySQL servers for data storage, a Redis cluster for caching, compute servers running applications on Tomcat and Nginx, Hadoop/Spark servers for data analysis, RabbitMQ servers for messaging, and miscellaneous servers for Jenkins, monitoring, bastion hosts, and security scanners. Their storage appliances include iSCSI and Fiber Channel SANs, totaling 1 PB of storage. They face challenges in building a reliable, scalable, and secure environment while improving business agility and optimizing for performance in the cloud. They need to make changes to their on-premises architecture to meet business requirements before fully migrating the solution. What change in the on-premises architecture should you make?
