The data center hardware infrastructure usually involves servers; storage subsystems; networking devices, like switches, routers and physical cabling; and dedicated network appliances, such as network firewalls.
A data center infrastructure also requires careful consideration of IT infrastructure security.
Solid management also allows admins to optimize resources for different workloads, and to more readily understand and handle the impact of any changes on interrelated resources.
Infrastructure management is often divided into multiple categories.
Increasingly, systems management tools are extending to support remote data centers, along with private and public cloud resources.
Management tools are also making extensive use of automation and orchestration to improve efficiency, reduce errors and comply with established best practices or business objectives.
However, the way IT infrastructures are created is continually changing.
Internet infrastructures are designed, built and operated by internet service providers (ISPs), such as Verizon and AT&T.Infrastructure may be centralized within a data center, or it may be decentralized and spread across several data centers that are either controlled by the organization or by a third party, such as a colocation facility or cloud provider.Data center infrastructure often includes the power, cooling and building elements necessary to support data center hardware.This notion has advanced into single-vendor systems that offer even tighter integration and management over compute, storage, network and virtualization.This advanced approach is called hyper-converged infrastructure (HCI).
