Data within a datacenter often spreads across numerous disks within a storage array. Effective storage management ensures proper backups, removal of obsolete backups, and efficient data indexing for retrieval, even in the event of component failure. Virtualization abstracts storage from hardware, converting it into cloud storage that permits flexible drive additions or removals and adapts to changes without requiring new dedicated storage servers.

Network
The network infrastructure comprises physical elements—wires, switches, routers, etc.—on which virtual networks are built. Cloud networks typically consist of multiple subnetworks with varying visibility levels, allowing the creation of virtual LANs (VLANs) and assigning dynamic or static addresses to network resources. Cloud resources are accessible remotely over networks like the Internet or intranet, enabling on-demand access to cloud services and applications.

Public, Private, and Hybrid Cloud Infrastructure

Public, Private, and Hybrid Cloud Infrastructures represent diverse models catering to distinct business needs.

Public clouds utilize third-party service providers, offering shared resources like applications and storage over the Internet.

Private clouds are exclusive to a single organization, providing dedicated infrastructure, enhanced security, and greater control over data and applications.

Hybrid clouds combine elements of both, merging public and private clouds, allowing seamless data sharing and workload portability. Additionally, the rise of multi-cloud strategies leverages multiple cloud providers, optimizing performance, mitigating risks, and enhancing flexibility across various platforms.
