This network diagram comprehensively outlines the various components of a corporate IT infrastructure and their interconnection methods. The server cluster, serving as the core of data processing and storage, is linked to the core switch via high-speed Ethernet connections. The core switch, in turn, connects the server cluster to the external internet through multi-tier routing and switching devices while providing seamless network access services to internal employees. To further enhance business continuity and data protection capabilities, load balancers and redundant power supply systems have been introduced. The entire architecture aims to support the company's digital operations and cloud service strategies.
