This document discusses data center architecture and describes the key components and benefits of a data center. It summarizes that a data center houses critical computing resources in a controlled environment to enable businesses to operate continuously according to their needs. It provides benefits like business resiliency, cost savings, rapid application deployment, and consolidation of computing resources. The data center architecture is designed based on layering with core, intranet and extranet server farms for reliability. It segments functions into front end, application and back end segments to support presentation, business and database servers respectively.

1. Pengenalan Data Center
