1) DMS (Device Management System) is a web-based remote device management system that allows unified management of embedded devices through features like remote monitoring, upgrades, control, and application deployment. 2) Traditional embedded device deployment faces challenges like high costs and complex maintenance due to issues like on-site installation and prehistoric remote update methods. 3) DMS aims to reduce total cost of ownership for customers by streamlining deployment, diagnostics, software updates, and support through its centralized remote management capabilities.
