The evolution of atypical data centerinvolves several key phases, each addressing specific technological and operational advancements:
Virtualization:The first major phase, where physical resources are abstracted into virtual machines (VMs) to improve resource utilization and flexibility.
Centralized:Early data centers were centralized, with all resources located in a single facility for easier management.
Multi-site and multi-cloud:Modern data centers extend across multiple locations and integrate with public
/private clouds for scalability and redundancy.
Distributed:Distributed architectures enable edge computing and decentralized processing, reducing latency and improving performance for geographically dispersed users.
These phases reflect the progression from traditional, hardware-centric designs to modern, software-defined, and cloud-integrated infrastructures.
